PRESSURE CONTROL EQUIPMENT Shaffer Hook-Ups can be used for pressure protection luring any type of drilling-"pressure drilling" with >ack-pressure control, normal drilling with mud control, lrilling with reverse circulation, drilling with air or gas -and for both "on-shore" and "off-shore" operations.

Shown in Fig. 1 is a typical pressure control assembly using Shaffer equipment-only one of a wide range of Shaffer assemblies used for various types of pressure control requirements.

Combination Rotating Blowout Preventers and Strippers Shaffer offers for maintaining a continuous pressure seal around the drill string-whether it is rotating, is stationary, or is being raised or lowered in the hole. Shown here is the Type 50 unit. For complete information, see pages 4808 through 4814.

One of Three Types of Blowout Preventers (two hydraulically-operated, one mechanically-operated) Shaffer offers to meet every pressure control requirement in both land-based and sub-sea drilling and production operations. In most of these basic types a further choice is offered-Single or Double designs. Shown here is Type LWS Double Blowout Preventer. Fo'I' complete 1'.nformation, see pages 4284 througf, 4807.

One of Many Types of Casing· Head Assemblies for modern casing and well-completion operations. Shown here is a Model "KD" Landing Head imitallation (double flange design on top-single flange design on bottom). For complete detnils, see pages 4818 through 4«J81.

BLOWOUT PREVENTERS Basically, Shaffer Blowout Preventers are available in "Type LWS" for both land-based and sub-sea operations ... and in "Type LWP" for production and well re-work applications. In each type, a further choice of "Single" or "Double" designs is available in most sizes. The "Double" design incorporates two separate ram compart-

Fig. 2 Type LWS Double Blowout Preventer-Sectional View

ments unitized into one compact body that saves con· siderable space in the hook-up over using two completely separate Preventers. Generally, the lower compartmen1 of "Double" units is equipped with rams for closing oft open hole-the upper with rams for closing around the drill string-thus providing pressure protection whethe1 the drill string is in or out of the well. Shaffer Preventers feature a deep-ribbed alloy stee body that combines important weight savings with higl strength factors to provide the required safety foi modern blowout protection. These Preventers featuri Pnd-opening construction so that ram changes may eas· ily be made by simply unbolting and swinging open thi encl section, as shown in Figs. 9 through 12. Note tha1 each ram and its operating mechanism is complete!} self-contained in the encl section, with all hydrauli< lines built into the hinge itself so that there is nothin~ to drain, no connections to break or re-make, wher changing rams or servicing the ram compartments. Shaffer Preventers are available in both "Single' and "Double" designs in most sizes-and with choice 01 studded, flanged or clamped connections. For full de tail.s, see page 4283 through 4307.

All Shaffer Hydraulic Blowout Preventers Incorporate the

SELF DRAINING CONSTRUCTION To prevent sand and mud accumulations from interfering with the operation of the rams, the bottoms of the ram compartments of all Shaffer Blowout Preventers are steeply sloped downward toward the bore of the well, with the rams supported on high guide ribs as shown in Fig. 3. These guide ribs are narrow so as to reduce to a minimum any chance of sand or mud gathering on the sliding surfaces. The little that might gather is quickly wiped off by the rams as they open or close. In addition to being narrow. these guide Fig. ribs ar~ also high above the steeply sloped bottoms of the Preventers, ~hus holding the rams far above any sand or mud that might accumulate. Since the steeply sloped bottom, along with the high support guide ribs, prevent detrimental sand and mud accumuiations from interfering with free ram travel, Shaffer Preventers are always reacly for use whenever pressure emergencies threaten.

TYPE 60 RAM ASSEMBLIES These incorporate all the latest Shaffer advancements in ram design and are used in Shaffer Type L 'WS Preventers (except in some 6" and 11" sizes, which use Type 61 Ram Assemblies-a similar design modified slightly to meet the small-bore limitations of these sizes). Type 60 Ram Assemblies-as a coniplef;e unit-can be installed to replace the same size Type 39H Ram .Assemblies, thus enabling operators to install the latest Type 60 ram design when overhauling Shaffer Preventers already in service. Also, Type 39H Ram Blocks and Ram Rubbers used with Type 39 Retracting Screws will fit Type 60 Ram Holders. Note, however, that the Type 60 Ram Blocks will not fit Type 39H Ram Holders-nor will Type 39 Ram Rubbers fit Type 60 Ram Blocks.

Following

Important Advantages:

Type 60 Ram Rubbers are molded with threaded trunnio1 nuts embedded in the rubber face sections. Rubber retaininf screws, inserted from the rear of the Ram Block, screw int< these nuts to firmly hold the Ran Rubbers in place on the blocks. Thi: not only provides a better anchorag-. but also assures a better face-to-fac• seal when the rams meet. Another important advancemen built into Type 60 Ram Assemblie: is the steel plates embedded top an< bottom in the leading face of th• Ram Rubbers. These plates contro extrusion of the rubber as the face: come together, forcing the rubber t• flow toward the seal (as shown ii Fig. 4 Fig. 4) for better sealing efficiency particularly at high pressures am under prolonged sealing operations. All Tvpe 60 Ram Rub be.rs a~·e symmetrical top and bottom, and can be installe1 w~th either face up. Th!s simplifies installation and also per 1mts the rubbers to be rnverted for additional service shoul1 they show more wear on one side than on the other. Rea arcs of the Type 60. Ram Rubbers are molded "L" shape1 to fit rnto grooves rn the ram blocks, thus anchoring th Ram Rubbers. The shoulders on the periphery of the Ram Blocks sup port the Ram Rubbers and control extrusion of the rubbe at these points as closing pressure is applied (See Fig. 7) Thus, more accurate control of rubber extrusion is effecte to provide optimum sealing efficiency between each ram an the upper inside face of the Preventer.

POSITIVE AND COMPLETE SEAL Whether shutting off open hole or around pipe, the seal obtained with Shaffer Preventers is positive and completely effective. The ram rubbers seal off securely, both where the rnms come together as well as where they contact the upper inside face of the Preventer body as shown in Fig. 5.

BLOWOUT PREVENTERS "FLOATING

11

RAM DESIGN

The advantages of this "floating" ram design are best illustrated by referring to Fig. 6 and Fig. 7. When Shaffer rams are in their normal retracted position as shown in Fig. 6, the portion of the ram rubber that is to seal off against the upper inside face of the Preventer body does not contact the body at all. In fact, the upper inside face has a gradual

SPACE-SAVING COMPACTNESS No other hydraulic preventer can match the compactness of Shaffer Preventers-and they also permit great savings in length and width requirements as well. Compare the dimensions of the Double and Single Preventers shown in the specification tables with any other similar hydraulic Preventer equipment, remembering that the Double Preventer is two gates in one, and you will readily see the entirely new standards of compactness these Preventers make possible.

NEGLIGIBLE MAINTENANCE

Fig. 7

slope to insure ample clearance between the ram and the body before the seal is made. This design insures frictionfree operation of the ram without any drag whatever against the body of the Preventer as the rams are closed. As the rams reach their closed position, they first seal off against each other and around the circumference of the pipe, thus closing off this portion of the Preventer tightly and securely against pressure leakage. Then as closing pressure continues to be applied, the portion of the ram rubber positioned between the ram block and ram block holder is squeezed upward by the closing pressure, thus sealing tightly against the upper inside face of the Preventer body as shown in Fig. 7. Because of this unique design, there is no drag or friction against the upper inside face of the body while the rams are being closed. It is only after a tight seal has been effected around the pipe that the ram rubbers squeeze upward to form an equally-tight seal against the upper inside face of the Preventer. When opening the Preventer, the same advantage is obtained. The ram rubber first pulls away from the upper inside face of the Preventer as opening pressure is applied, but there is no movement of the ram until after the rubber has pulled away from the upper inside face, thus eliminating frictional drag as the rams are opened. This important Shaffer feature assures easy opening and closing of the rams without excessive friction.

Aside from infrequent changes of the ram rubbers, there is virtually nothing to wear in the ram assemblies, and the operating cylinders are equally trouble-free. All working parts are fully enclosed within the cylinders. The piston rod ram shafts are of stainless steel and each is packed off with two sets of packing. The piston assembly consists of a steel core and molded replaceable lip type rubbers similar to the construction of slush pump pistons. Because the fluid is clean and non-abrasive, there is virtually no wear whatever to the pistons or piston chambers-and therefore little maintenance is required.

WIDE CHOICE OF POWER Hydraulic pressure for operating the rams can be supplied by the means available at the rig but we recommend that hydraulic oil in a closed system be used. It is the most efficient and economical method, for the hydraulic oil not only protects all of the parts of the system, but also has lubricating values that subsequentially reduce wear and maintenance and it will not freeze in cold climates. In a closed system there is no waste of oil and fluid costs are negligible.

QUICK AND EASY RAM CHANGES Still another outstanding Shaffer feature is the ease and simplicity of making ram changes, as shown in the following illustrations. CHANGING RAMS IN "TYPE LWS" PREVENTERS:

WELL PRESSURE ASSISTS SEALING To insure easy and quick closing of the rams, the pressure is equalized on the front and back faces of the ram assemblies. Note that the bottom portion of the Shaffer ram compartment is recessed and deeply sloped downwardly toward the bore, with the ram supported on guide ribs that are elevated above the bottom of the compartment. This design not only prevents mud and sand accumulation from interfering with the operation of the rams, but also permits the pressure of the well to build up behind the rams as Fig. 8 shown in Fig. 8 and this equalized pressure assists in the closing and sealing operations against the highest well pressures.

Fig. 9 End Section is unbolted

Fig. 10 End Section is swung open

CONVENIENT CENTRALIZED CONTROL Complete control of the rams can be conveniently centralized in a control panel located alongside the driller, or at any other desired location. By simply moving control levers a few inches, the rams can be opened or closed in a matter of seconds.

BLOWOUT PREVENTERS (Patented)

TYPE LWS BLOWOUT PREVENTERS

Fig. 13 Type LWS Double Blowout Preventer-Front View

Fig. 14 Type LWS Double Blowout Preventer-Rear View

Shaffer Type LWS Blowout Preventers feature a deepribbed, alloy steel body construction that combines high strength factors with important savings in weight. So popular have these Preventers become in modern drilling operations that they are now made in sizes as large as 20", pressure ratings as high as 15,000 psi W.P. and in most sizes they are available in both "Single" and "Double" designs-with choice of studded, flanged or clamped connections. Thus, there is a size and type available for virtually all normal drilling operations.

OPERATION

The "Double" design not only combines two separate ram compartments unitized into one rugged, compact body, saving vertical height-but also is shorter in length and narrower than other comparable-size Preventers. This threeway compactness saves space in the hook-up, reduces storage requirements and cuts transportation costs.

END-OPENING CONSTRUCTION The Type LWS Preventers are constructed with end opening doors which are provided with door hinge pins drilled with dual fluid passages that eliminate the need for complicated flexible fluid joints to prevent the loss of fluid when the doors are opened.

Ordinarily the Type L WS Preventers are furnished fo1 hydraulic closing and opening of the rams (with provisior for manual closing), but the opening operation can be dorn only by hydraulic pressure. For subsea installations botI the closing and opening of the rams are controlled ]1y dra ulically. Completely Automatic Ram Locks are an importan option built into these Preventers. Be sure to check page: 4296 to 4299 for complete details.

INTEGRAL HINGE PIN PRESSURE PASSAGES All Shaffer Type LWS Hydraulic Blowout Preventers are furnished with fluid hinges. The hinge pins for the door are drilled for fluid passages as shown in Fig. 16. This eliminates the need for complicated flexible fluid joints to permit the doors on the Preventer body to swing open without loss of fluid and permits full hydraulic control in moving the rams in and out of the ram compartment. The hinge pin is removed by securing the Preventer door to the body with cap screws, then removing the retainers and gently tapping the pin out of the body. After removing the hinge pin it is recommended that the hinge pin 0-rings be replaced. vVhen replacing the hinge pin, the 0-rings and pin should be lubricated with a light grease.

The Type LWS Double Blowout Preventer shown above in Fic;. 13 is also available with this Type B Automatic Ram Lock design ... and this Stngle Blowout Preventer is a!so available with the manual ram lock as shown in Fig. 13.

Type LWS Preventers are available with a wide selectio of outlet arrangements for connecting mud and presstu« relief lines. Number and arrangement depend upon the siz of the Preventer, the size outlets desired and other factor> TVrite for detciils.

RAM ASSEMBLIES

PRESSURE MANIFOLDS

The Ram Assemblies used in Type L WS Preventers are the Type 60 Ram Assemblies described, illustrated and tabulated on pages 4300 through 4302. Full details on the Ram Blocks, Ram Rubbers, Ram Holders and the complete Ram Assemblies are given on these pages, together with important information on the carefully-engineered seal they provide against high well pressures.

Type L WS Preventers are designed to operate on 1500 PSI accumulator pressure systems-the rating recommended for longest operating life and minimum maintenance. However, these Preventers can also be used on 3000 PSI svstems without modifications. · As shown in Fig. 19, the pressure manifolds for operating the Type LWS Blowout Preventers are bolted to the back of the body and align with passages built into the Preventer

Fig. 17 Type LWS Double Preventer with one door of the upoer compartment open showing the rams ready for ea<;y rep/ac~ment

CHANGING RAMS The Rams are easily and quickly installed in Type LWS Preventers by merely unbolting and swinging open the encl doors as described and illustrated on page 4285. Since the Hinge Pin used in Type L WS Preventers permits full :fluid passage whether the end doors are open or closed (Fig. 16), the ram shaft that holds the Fig. 18 rams can be easily moved in or out \vhile changing rams by simply activating the power system. This permits maximum ease in both installing the rams and then checking their operation while the end door is open. As illustrated and tabulated on pages 4300 through 4302. Ram _-\ssemblies are available for closing off open hole as well as fo1· closing off arnund drill pipe, tubing or casing.

Fig. 19 Heavy lines diagrammed above show the fluid flow through the manifold as Type LWS Preventers are opened and closed. Solid Jines indicate Jines that open each set of rams-dotted lines, those that close each set of rams. Arrows indicate the eight threaded outlets for connecting to pressure system. Only four of these outlets need be used, as explained in the text

to admit fluid under pressure into each end of the cylinders for opening and closing the rams. There are two sets of manifold piping, as diagrammed in Fig. 19, one set for the upper ram compartment and the other set for the lower ram compartment. In each set of manifold piping, the upper pipe controls the opening of the rams and lower pipe controls the closing of the rams. Threaded outlets are provided in the Preventer for connecting pressure lines to the hydraulic system, as shown in Fig. 19. Although two outlets are provided in each of the four pressure lines-one on the left and the other on the right side of the Preventer-only one of the outlets in each line needs to be connected to the pressure system, since both right and left outlets open into the same manifold pipe. Therefore, only four connections need be made between the Preventer and the pressure system-one to each manifold pipe-using whichever manifold outlet is most conveniently located.

MULTIPLE WEIGHT SAVINGS TYPICAL SIZE AND WEIGHT DATA ON TYPE LWS DOUBLE BLOWOUT PREVENTERS

The table al right shows the approximate weight savings made possible with Type LWS Double Blowout Preventers. There are many ways these weight savings cut costs in modern drilling operations • . . ii'- The 7 1/16" bore Type LWS Double Preventers weigh approximately half as much as other Preventers of comparable size-yet have a working pressure a.s high as 5,000 psi. This brings new safety lo operations such as drilling-in, diamond coring, well re-working and similar jobs where the installation of heavy equipment is frequently impractical for the short duration of the job. ilJll-. In remote locations where transportation costs are high, even the 13%" bore Type LWS Double Preventers save as much as 35% in weight. This adds up to important all-around savings-in shipping costs, in warehousing, in rig-up time and labor costs-in savings all along the line.

.,..._ ln iungle or arctic operations where roads are non-existent or impassable part of the year, Type LWS Double Preventers can be transported fully assembled (not piecemeal) by normal air cargo and helicopter equipment. Not only is important time saved in rigging up, but the risks and extra labor of dis-assembling and re-assembling critical pressure control equipment are eliminated.

BLOWOUT PREVENTERS (Patented)

AUTOMATIC RAM LOCK (Patented}

for Type LWS Preventers The most important advancement in blowout preventers since hydraulic ram operation, it is available only with Shaffer Hydraulic Blowout Preventers. It is most commonly ordered with Type LWS equipment, although Type B and Type E Preventers can also be equipped with this revolutionary advancement when so desired. The Lock is a simple, positive built-in mechanism that autornatically locks the rams in the "closed" position

without secondary systems or manual operations of a kind ... rnaintains the lock indefinitely without need f hydraulic pressure ... yet releases irnrnediately whenev desired. Major state safety commissions have recognized t reliability of the Shaffer Automatic Ram Lock by [ proving it as a dependable replacement for manual lo< ing devices!

POSITIVE OPERATION

When the rams reach their closed position (either closing off open hole or closing off around the drill string), locking elements at the end of the hydraulic piston are automatically forced into locking recesses provided in the cylinders. (see Fig. 32).

Unique flat disc springs, similar to those used

j

many years of trouble-free service in Shaffer Down-H, Tools, maintain the necessary sealing force to h< the rams firmly in place without need for hydraulic pr

(Right) Enlarged view of Automatic Ram Lock showing the simple, al/mechanical design that holds the rams in closed position regardless of fluctuations in the pressure of the hydraulic operating system.

BLOWOUT PREVENTERS (Patented)

AUTOMATIC RAM LOCK (Patented)

for Type LWS Shaffer Preventers sure, manual tightening 01· any other outside force. Even the highest well pressures cannot force the locks openor move the ram.> from their "Closed" position. However, when it is desired to open the rams, the

simple act of applying hydraulic pressure in a ramopening direction to the operating pistons automatically unlocks the mechanism and opens the rams immediately!

MULTIPLE ADVANTAGES Without question, this is the simplest, most fool-proof locking device yet perfected for blowout preventers. There's nothing to remember-or forget-in the rush of blowout emergencies ... no separate ram-locking operations. Simply close the rams and they lock automatically. Then they stay locked whether or not pressure is maintained in the operating system. To open, simply apply pressure in a ram-opening direction and the locks release aut01ncttically as the rams open. There's nothing to unscrew-no manual operations of any kind (other than simply moving the conventional ram control lever at the rig floor to the desired ram position).

Equally important, no secondary hydraulic systems or controls are required to actuate the ram lock-no added hoses to leak or break-no extra equipment to install or maintain. The Automatic Ram Lock is completely selfcontained-completely self-actuating! The Automatic Ram Lock is designed for use with 1500 PSI accumulator systems - the pressure rating recommended for longest life and minimum maintenance. However, 3000 PSI systems can also be used without modifications and without need for regulator valves. Note that, with the Automatic Ram Lock, there is no risk of costly failures in the fittings, hoses or other parts of the ram locking system-beccmse no such parts llre needed in the Shaff er design!

MANY APPLICATIONS On sub-sea operations, in particular, this new Shaffer :ievelopment is almost indispensable. It assures positive ram lock without the problems and costs of sending :livers down to manually lock the rams each time the Preventer is closed. And, since no auxiliary hoses or hydraulic systems tre needed with the Shaffer Ram Lock, there are no ;omplex hook-ups to make, no additional control lines to )l'eak or deteriorate under tidal abrasion and stresses, to extra controls to worry about. Moreover, where waters are too deep for diver access he Automatic Ram Lock permits complete blow-out proection - including ram locking - without subsurface perations and without need for duplicate hydraulic sysems to remote depths. In land-based operations, the positive and foolproof

simplicity of the Automatic Ram Lock brings new safety to blowout protection. There are no delays, no risks to personnel, while someone goes below the rig to manually lock the rams during blowout emergencies. Also, there are no problems of forgetting to lock the rams during the excitement of a threatened blowout. With the Automatic Ram Lock, you simply close the rams-and they lock llUtomlltiwlly. Simply open the rams, and they unlock automatically. Y?t, no other factors (such as high well pressure, loss of hydraulic pressure in the system, vibration, shock, high temperature fluctuations, etc.) will unlock the rams until the operator so desires! See page 4298 for exploded view of Type LWS Preventer with Automatic Ram Lock. The table on page 4299 shows the sizes of Type LWS Preventers in which the Automatic Ram Lock is most commonly supplied.

RAM BLOCK HOLDERS The alloy steel Ram Block Holders, as the name implies, surround the Ra Blocks and hold both the Ram Blocks and Ram Rubbers in place so that they c: be closed and opened by the piston rod ram shaft which fits into a slot cut in the back of each Holder. The Ram Blocks are held in the Holders by retracth screws (two screws for each Ram Block), and are so mounted that each Ra Block is permitted a slight rotary movement to assure positive alignment of t: ram faces for a perfect seal. RAM BLOCKS The alloy steel Ram Blocks fit within the Ram Block Holders and are surround• by the Ram Rubbers. They are of ample thickness to withstand more than the f1 rated pressure of the Preventers. RAM RUBBERS The Ram Rubbers (Fig. 38) surround the Ram Blocks and are made of a tow specially-compounded rubber that permits them to extrude slightly under cot pression to insure a pressure-tight seal. The Type 60 Rams are the latest Shaff advancement in ram design and provide important advantages ... 1. The Type 60 Ram Rubbers are anchored to the Ram Blocks from the back each Block by retaining screws "A" (Fig. 39) that fit into threaded trunnion nu "B" embedded in the Ram Rubbers. Thus, the entire face of the Rubber, where seals around the pipe as well as against the face of the opposite Ram, is soli tough rubber without any holes or exposed metal surfaces to reduce the effectiv ness of the seal. 2. As the Type 60 Rams close around the pipe (or against each other) steel plat "C" (Fig. 40), bonded into the face of each Type 60 Ram Rubber act as pisto: to force reserve rubber into the sealing area. Thus, the full resiliency of ti specially-compounded rubber is utilized to maintain the leak-tight seal across ti face of the Rams. This added reserve of rubber-with extrusion fully controlled l the steel plates-assures tighter sealing, even under prolonged pressure shut-oft 3. The double bands "D" (Fig. 40) of Ram Rubber around the outer periphery each Ram Block reduce sealing resistance and permit a tighter seal with less clo ing force. These double bands also assist the sealing effectiveness should the ope ating pressure be reduced. 4. By simply installing the proper size of Type 60 Ram Rubbers, most Type 1 Ram Blocks can be used for sealing around several pipe sizes (as shown on pa1 4301), thus eliminating need for purchasing separate Ram Blocks for each pipe si' For example, only four Ram Block sizes are required for handling nine popul: sizes of Ram Rubbers ... 2%" and 2'%"-4" and 4¥i"-5", 5'\1i" and 5o/ia"-a1 6" and 7". OFFSET RAMS In order to inovide complete control when making dual completions, Shaff Offset Rams can be furnished. The Shaffer Type AD Dual Tubing Hangers cl signed to support two production strings are described in the Well Head sectio Offset rams are furnished to API centerline standards. Special Offsets can also i furnished, as required. Offset Rams can also be furnished with one opening whi the second string does not need control and is to be nm later. ' SELF-CENTERING FEATURE

Fig. 39

Fig. 40

All Shaffer Ram Assemblies used for closing c around pipe are of self-centering design (see Fi 36) with angular guides protruding alternate top and bottom as shown. As the rams mo" toward their closed position, these guides engai the drill pipe and center it within the bore of tl ram. Then, as the rams continue closing,, ti guides telescope into recesses provided in the o posite mm blocks, thus permitting the faces the ram blocks to seal tightly together. This self-centering feature is important, for automatically aligns the drill string with the ra bore to insure a positive seal whether or not t: drill string normally hangs centered in the casin

TYPE LWP BLOWOUT PREVENTERS

Fig. 42

Type LWP Single Blowout Preventer-Front View

The Shaffer Type L WP Hydraulic Blowout Preventers are designed for use where a compact, light weight, hydraulically operated blowout preventer is desirable for various production operations. It is particularly adaptable for use when reworking wells and for remedial work in producing wells.

The Type L WP Preventers are furnished either in Sin~ or Double design. The Single units can be furnished wi self-centering rams to close around pipe or with rams shut-off open hole. In the Double design the upper co1 partment is equipped with self-centering rams to clc around pipe while the lower compartment is equipped wi rams for complete shut-off. The Type LWP Blowout Pi venters are smaller in width, length and height than oth Shaffer Preventers. Although the Type L WP Preventer is lighter in weig than other Shaffe1· designs, its body, cylinder block, doc and all other parts are of the same materials as in t heavier Preventers. The Type LWP Preventers have end opening doors whi are. provided with door hinge pins drilled with dual fh passages that eliminate the need for complicated flexil fluid joints to prevent the loss of fluid when the doors 2 opened. The Type L WP Preventers are furnished in two sizeE 6" and 8", both 3,000 PSI W. P. All Type LWP Preventi can be furnished with either studded flange connectic (Fig. 43) or bolted flange connections.

OPERATION Ordinarily Type L WP Preventers are furnished for be manual and hydraulic closing of the rams but the openi operation can be done only by hydraulic pressure.

MANUAL HYDRAULIC OPERATION

Fig. 43 Showing the Type LWP Double Blowout Preventer

Although usually opened and closed by a hydraulic po;1 unit, Shaffer Type LWP Preventers may be operated means of a hand pump. The pump is connected througl~ Control Panel for selecting either the upper or lower l'< compartment as well as the closing or opening operation For the operating fluid, water with a rust inhibito1· m be used; but we recommend the use of hydraulic oil in closed system because of its lower over-all cost, its savir in maintenance and its low freezing point.

TYPE 64 RAMS FOR TYPE LWP PREVENTERS

Type 64 Ram Assembly with Rams for complete shut-off

The Type 64 Rams for closing around pipe and for comlete shut-off are designed as indicated in Fig. 45 and Fig. 6. These Type 64 Rams consist of a Ram Rubber, a Ram :lock, and a Ram Block Holder fitted together as shown in ne inset view at right and in the table below. The rams or closing around pipe have the self-centering feature emloying angular guides that center the pipe into the bore of l1e rams as the preventer is closed. The rams can be fur.ished for complete shut-off and for closing around pracically any size pipe that will pass through the bore of the 1reventer as shown in the table below.

Fig. 46 Type 64 Ram Assembly with Rams for closing around pipe

Fig. 47 Fig. 44 Showing the Shaffer Type LWP Hydraulic Single Blowout Preventer with one door open and the Ram extended for easy replacement

CHANGING LWP RAMS The Rams are easily and quickly installed by removing ;he cap screws and swinging open the doors at the ends of ;he preventer body. As the doors open the rams are autonatically withdrawn from the preventer body. By applying 1ydraulic pressure to the pistons the rams are moved out to :lear the doors, allowing the rams to be lifted up and off ;he ram shafts. To replace the rams they are lowered vertically down onto the ram shafts, the hydraulic power turned Jn to return the rams into the door cavities and the doors :losed and bolted.

RAM RUBBERS The ram rubber is prevented from downward movement by the bottom of the ram block holder. Thus, when closing pressure is applied, the ram rubber seals across its front face and is then expanded upward to effect a pressure-tight seal against the upper inside face of the preventer body. This design eliminates the necessity for using ram rubber retaining screws. The rubber used is the best and toughest obtainable and of sufficient elasticity to conform itself readily to the pipe. By its design it will withstand hard usage and will give maximum rubber containment and control.

TYPE 64 RAM ASSEMBLIES Sixes and Parts Numbers 9"' Bore

1-I O.D.

RAM RUBBER FLOW DURING CLOSING As the hydraulic pressure is applied in closing the preventer, the rams move toward each other and the rubber face is the first to make contact. As increasing force is applied to the rams by the hydraulic cylinder, the ram blocks come into contact. When this occurs, the ram blocks cannot move any closer and, as further pressure is applied, the ram block holders are forced closer together. As the holders thus move toward each other, the rubber is forced to move upward to seal against the upper inside face of the preventer body and to move forward to add rubber to the already sealed faces on the front of the ram. The flow of rubber on the front face as well as on the upper inside face of the preventer body is caused by the relative motion between the ram block and the ram block holder in decreasing the volume in which the rubber is contained.

MECHANICAL CONTROL GATES Shaffer Mechanical Control Gates are ideal for blowout protection on low-budget operations. Not only will they close and hold against high well pressures, but their positive screw-thread drive will safely hold these high well pressures indefinitely after the rams are closed. Mechanical Control Gates are available in a wide range of sizes, and are available in a choice of "Single" or "Double" designs. In the "Double" design, two ram compartments are unitized into one compact body-the upper compartment equipped with rams for closing off around the drill string, the lower compartment equipped for closing off open hole. Or two separate "Single" Gates may be used, similarly equipped-and some operators use three "Singles," or a "Double" and a "Single" for stripping couplings through the rams under pressure, or for closing off around "mixed" strings.

COMBINATION ROTATING BLOWOUT PREVENTERS AND STRIPPERS (Patented}

TYPE 50

Xot only does it combine in one device every feature needed for successful and simplified drilling under pressure with the kelly and drill pipe ordinarily used, but it maintains a continuous seal around all elements in the drill string (except for such abnormally large diameters as the bit or reamer) and requires no special operations for handling the pipe. In addition, it will seal off around any shape kelly, whether round, square, hexagon or octagon and will also seal on any type of drill pipe, whether flush joint, upset or coupled.

Fig. 59 Shaffer Type 50 Combination Rotating Blowout Preventer and Stripper

The use of the Combination Rotating Blowout Preventer and Stripper with Shaffer High Pressure Drilling HookUps is illustrated on page 4283. The unit is not only ideal for normal pressure drilling operations, but it also offers distinct advantages when drilling-in with oil or very light mud and is also unequalled for drilling with air, gas or for reverse circulation.

With the Combination Rotating Blowout Preventer and Stripper, the operator may drill and strip drill pipe in or out of the well under pressure. When adding or removing pipe in the drill string, it is only necessary to raise the drill pipe through the Stripper, add or remove the pipe, reconnect the kelly and lower the string for continued drilling operations in the normal manner. When running the oil string or other pipe, the rotating assembly may be removed and a stationary stripper inserted in the body, thus increasing still further the utility of the Rotating Preventer. CONSTRUCTION

The body houses a Rotating Assembly for sealing around a kelly during rotation and for packing off drill pipe, tool joints, drill collars and couplings while the string is being run in or pulled out of the hole. Ordinarily the body is furnished with one large overflow outlet and two 2" outlets for fill-up connections. QUICK RELEASING BONNET

Fig. 60 Here is shown the method of inserting the Rotating Assemb / y and Stripper through the Quick Releasing Bonnet into the body

A spring latch on the side of the Bonnet locks it in either closed or open position. Pulling the latch and turning the Bonnet one-sixth turn to the left unlocks the rotating assembly for removal. Onesixth turn to the right and it locks itself in closed position. It is only necessary to open the Bonnet and the entire internal mechanism as a unit can be withdravvn to permit removal of the bit.

ROTATES WITH KELLY

At the upper end of the Rotating Sleeve are driving splines. A floating drive unit with a hole to conform to the shape of the kelly engages these splines s9 that the rotating assembly is driven by and rotates with the kelly. The drive unit is removed automatically with the kelly. At the lower end of the Rotating Sleeve is the Stripper Rubber which seals around the kelly or drill pipe. Since the Stripper Rubber is attached to the Rotating Sleeve and rotates witb the kelly, there is practically no wear on the Stripper Rubber while drilling.

ROTATING SLEEVE

A rotating Sleeve splits compounc loads into the two components of pun radial and pure thrust and carries eacl: of these components on separate bear· ing assemblies, preventing thrust shod and vibration from building up on thf radial bearings and vice versa. The ra· dial roller bearings are placed a consid erable distance apart so as to providf maximum resisting moment to wobble and off-center strains. All bearings an prepacked with a high temperature am high speed stabilized grease that resisti oxidation and has excellent lubricatinf properties, even at temperatures as higl as 275°F.

ROTATING SLEEVE SEALS

The seal between the rotating sleev1 and the stationary housing is provide< by a chevron Packing Seal, as describec on page 4309. Since friction and wear are present adequate lubrication must be main tained to minimize this condition. It i recommended that the seals be lubri cated at least once every three to fou hours depending upon the conditions en countered. To facilitate proper lubrication th use of a Pressure Lubricator is strong}: recommended to assure continuous lul: rication with less effort and more effec tiveness.

COMBINATION. ROTATING BLOWOUT PREVENTERS AND STRIPPERS (Patented)

CHEVRON PACKING SEAL The Packing Seal consists of chevron packing rings separated by brass spacers, with brass top and bottom adapter rings. These chevron rings pack against a hard-chrome, alloy steel liner inserted in a recess on the outer periphery of the Rotating Sleeve. This liner is removable and can be replaced when worn or scored. The entire packing assembly is inserted from the bottom, being held in place by a retainer ring which also supports the lower automatic body seal. The pacl(ing unit is of a special design. The separators and the bottom adapter ring have a rounded extension at the top which fits into a corresponding groove in the chevron packing ring. This insures a uniform distribution of pressure during sealing action, thereby locking the separators in place and thus reducing the wear on tl1e packing assembly and its housing. Since chevron packing is automatic, it does not require manual tightening. Also, the higher the pressure, the tighter the seal. Parts List for Chevron Packing Seals is given on page 4314. Fig. 61 Showing Chevron Packing Seal

SEALS VARYING DIAMETERS AND SHAPES The salient feature is the Stripper Rubber (Fig. 62) which seals automatically around varying diameters and shapes in the drill string. The higher the well pressure, the tighter the seal. And not only does the Stripper Rubber seal around the drill i1ipe, but when using a kelly of suitable size in relation to the size of the drill pipe, a perfect seal is also maintained around the kelly. The Stripper Rubber maintains a constant seal, expanding and contracting to pass the drill pipewhether flush joint, upset or coupled-as well as sealing off the varying diameters of tool joints, subs and drill collars as they pass through the unit. A patented 2xpanding Eteel barrier composed of steel latches locked to the inside top encl of the Shipper prevents extrusion of the Rubber when subjected to high pressures Jr abnormal expansion.

I

The ideal installation for modern pressure control operations is the Shaffer :::ombination Rotating Blowout Preventer and Stripper used with the Shaffer Hydraulic Double Blowout Preventer. Such an installation provides complete protection against pressure emergencies ,vhether drilling the well with mud control or under pressure. It permits the iperator to drill under pressure without substituting any special drilling equipnent and with no loss of time or complicated operating procedures.

Fig. 62 Showing Stripper Rubber Sealing Around Kelly

LUBRICATION OF SEALS

The Pressure Lubricator shown in Fig. 63 has been designed to provide adequate lubrication for the rotating sleeve seals of the Shaffer Combination Rotating Blowout Preventer and Stripper. The lubricator is operated by compressed air which is usually available at most drilling rigs. The air actuates a small piston which in turn raises and forces the lubricant through a hose connected to a grease fitting located in the stationary housing and then through a port to the seals. The use of the Pressure Lubricator assures continuous lubrication and is a selfcont.ainecl unit made to be used on a 50 lb. lubricant pail (not supplied) by simply inserting the suction pipe into the lubricant. The quantity of lubricant used can be regulated by varying the piston speed through the air supply. Fig. 63 Pressure Lu[)ricator

As the lubricator is fully automatic and requires little attention, the lubrication of the seals is clone with no effort and with complete effectiveness.

COMBINATION ROTATING BLOWOUT PREVENTERS AND STRIPPERS (Patented)

TYPE 50 FEATURES OF THE SHAFFER COMBINATION ROTATING BLOWOUT PREVENTER AND STRIPPER

The Shaffer Combination Rotating Blowout Preventer and Stripper has an improved Stripper Rubber that has been tested to pressures in excess of the rated working pressures of the Rotating Preventers. This Stripper Rubber fits the kelly snugly and rotates with it so that the only wear during rotating is caused by the sliding action of the kelly through the Stripper Rubber as hole is made. Additional drill pipe is added to the drilling string in the same manner and speed as when drilling without this safety equipment. And, since any increase in well pressure seals the rubber more securely against the kelly or drill pipe, protection is provided against pressure emergencies without manual operation of any kind.

An important feature in the use of this Preventer is the quick and easy releasing of the internal rotating assembly by the Quick Releasing Bonnet. This permits the entire assembly to be removed from the Preventer with the drill string. The seal between the Rotating Assembly and the body is made by two automatic lip-type body seals recessed in the stationary housing. DRILLING WITH AIR OR GAS

Whether cuttings are blown up around the annulus 01 circulation is reversed, the Preventer provides a sealing unit across the annulus and around the drill string. Returning air or gas is directed out of the well through a flanged outlet below the sealing point and to 2 conductor pipe which leads to a disposal area. The packing element rotates with the string and provides effective packofl during drilling operations. When casing is landed, the rotating assembly may be replaced with the prope1 size of Casing Stripper (described on op. posite page). This allows the operator tc perform all necessary operations to com plete the casing landing job without re moving the Blowout Preventer or creat ing conditions over which the crew doe: not have full control. As there is no mud column to contro pressures and formation pressures ac quickly, a double Preventer or two singl1 Preventers should be installed below th• Rotating Preventer.

TYPE 50 DRILLING WITH GAS

When gas of sufficient pressure and volume is available, as from a nearby well, gas drilling is frequently very desirable. There is, of course, the danger of fire and blowouts-therefore, the protection provided by the Shaffer Combination Rotating Blowout Preventer and Stripper is essential to keep the well under control. The gas return is carried to a safe distance from the well, where it is; flared. EFFECTIVE SEAL NECESSARY WITH REVERSE CIRCULATION

The use of reverse circulation naturally requires an effective seal between the drill string and the casing during the drilling of the well. Moreover, a means of stripping the drill string into the well when adding pipe or making round trips is recommended since this not only reduces the work of the crew but also provides additional safety. The Shaffer Combination Rotating Blowout Preventer and Stripper has been used to meet these requirements and, because of its design, may safely be used under the pressures that are encountered during the drilling of a well. Although reverse circulation was first used when drilling through producing zones, it has since been employed for penetrating other sections where formation data are desired and where the formations are adaptable

to this method of drilling. It is therefore necessary under most circumstances to provide a means of switching from normal to reverse circulation and vice versa. A common method employed for this is illustrated in Fig. 64. Two lines lead from the pump manifold, one to the rotary hose stand pipe and one to an opening into the annulus between the drill string and the casing. An additional line is run from the stand pipe to the mud pits. A Shaffer High Pressure Hook-Up is shown in Fig. 64 to provide for either reverse or normal circulation. With the connections made as shown in the drawing, reverse circulation occurs when valves 1 and 4 are closed and valves 2 and 3 are open. If it is desired to switch to normal circulation, valves 2 and 3 are closed and valves 1 and 4 are open. The Shaffer Combination Rotating Blowout Preventer and Stripper provides the only equipment necessary to seal continuously around the drill string and to make connections and round trips with maximum convenience and safety. Since reverse circulation is now being used for drilling sections of a well in addition to the producing zone after casing has been cemented above that zone, the Shaffer Combination Rotating Blowout Preventer and Stripper has the advantage of providing for the running of the oil string or other pipe. The rotating assembly is merely replaced by a stationary stripper assembly inserted in the body of the Rotating Preventer.

CASING STRIPPERS (Patented)

Fig. 65 Stationary Casing Stripper Assembly

When running in casing under pressure, the Stationary Casing Stripper Assembly as shown in Fig. 65 used with the Shaffer Combination Rotating Blowout Preventer and Stripper, will provide a perfect means for handling any type of casing with the minimum of effort and delay. With the complete shut-off rams in the lower compartment of the Double Blmvout Previ;nter first closed and with the removal of the complete Rotating Assembly, the Stationary Casing Stripper Assembly is substituted for it and locked in

place by the latched Quick Releasing Bonnet. The casing is then ready to be run through the Stripper, which is essentially the same as the Stripper described on the previous pages. It will handle standard coupled or flush joint pipe with equal facility. When the Stripping Equipment or the Rotating Assembly has been removed from the body of the Rotating Preventer, a sealing plate at the top of the Preventer body can be· furnished on special order for completely closing in the well.

COMBINATION ROTA TING BLOWOUT PREVENTERS AND STRIPPERS (Patented)

TYPE 50

The Shaffer Type 50 Combination Rotating Blowout Preventer and Stripper incorporates all the features of construction and operation that have been described and illustrated on the previous pages. This type is adaptable to all kinds of drilling operations and is especially recommended in drilling through 10%" casing and larger. When it is used with the Shaffer Blowout Preventers that provide both for closing around the pipe in the well and for complete shutoff when tile pipe is out of the hole, even wider control against pressure emergencies is obtained. It is ideal for drilling with air or gas, or for reverse circulation where an effective seal is necessary. And, because of its construction and operation, it provides maximum facility for changing back and forth between reverse and normal circulation. This facility is shown graphically on page 4310 where the procedure to be followed is clearly defined. INSTRUCTIONS FOR ORDERING

When ordering Shaffer Combination Rotating Blowout Preventers and Strippers, specify size, A.P.I. bottom flange connection, size of outlet and whether flanged or screwed, size and shape of Kelly, size of drill pipe and drill collars. RECOMMENDED SPARE PARTS

When ordering parts, give size and serial number of Rotating Preventer and if possible show purchase order number under which original equipment was obtained. For domestic use, the following parts are recommended: An ample supply of Stripper Rubbers, Chevron Packing, automatic Body Seals and automatic Bearing Seals. For export use, the parts ordered will depend upon usage and the length of time required to obtain them. Reference to the Service Manual covering installation, operation and maintenance, which is included in shipment with each Rotating Preventer, will indicate the parts generally requiring replace- A mcnt.

One (1) Stripper Rubber is included with each Preventer. When ordering, specify size and type of rubber.

The illustration at left shows, in detail, the various parts in the Seal Assembly and the Stripper A ssembly that are numbered and listed in the two tables below. To service the chevron Packing Seal , the eight Stripper Rubber Cap Screws (Part No. 60) and the twelve Str ipper Rubber Holder Cap Screws (Part No. 65) are removed. The R etainer Plate (Part No. 49) is then removed by unscrewing the twelve Retainer Plate Cap Screws (Part No. 54), thus exposing the entire chevron Packing Seal for easy replacement.

•

Before re-assembling the unit, it is recommended that the Stripper Rubber be carefully inspected for wear or damage, and that the Stripper Rubber Holder Lip Seal (Part No. 59) be checked and replaced if it shows any wear. All of the Cap Screws (Part Nos. 54, 60 and 65) should be tightened carefully around the circumference of the units to insure un iform a lignment of the parts. This iE particularly important with respect to the Stripper Rubber Cap Screws (Part No. 60) because uneven tighten ing of these screw~ can throw the entire Stripper Rubber out of alignment, thus causing leakage and undue wear. To prevent uneven tightening of the Stripper Rubber Cai: Screws, it is recommended that the Cap Screws on opposite side! of the unit first be tighten ed-then those at right angles to the firsi two be tightened-then the remaining in-between Cap Screws bE tightened. This procedure will help to insure the Stripper Rubbei being seated uniformly against the Stripper Rubber Holder foi proper alignment.

Suggested Extra Parts: 1 each: Spider w/Guide Spring Dart Rubber

Records show that inside-the-pipe blowouts are the most common of all blowouts because there is less mud to displace inside the pipe and the mud column inside the string can become more easily unbalanced when pulling or running pipe. Then, when the outside Preventer is closed around the drill string, additional pressure is exerted on the column inside the pipe, increasing the risk of a blowout. The Shaffer Inside Blowout Preventer (Fig. 69) stands in a ho~r on the rig floor, ready for quick insertion into a tool-joint whenever needed. It features a spring-loaded valve (held open by a releasing pin while the tool is made up on the~joint) that seals against upward pressure in the pipe, but readily opens to downward pressure for circulating fluids into the well. It can be left in the string as long as necessary until pressure control is re-established; for it has the'same O.D. as a tool joint and readily passes through Preventets and similar equipment.

LOWER KELLY COCK For Blow Out Protection The Lower Kelly Cock is installed between the kelly and drill string as a permanent part of the drilling hook-up. If a blow out threatens, the Lower Kelly Cock is closed and an Inside Blowout Preventer is installed above the Lower Kelly Cock. The Lower Kelly Cock is reopened and stripped into the well (with additional joints of drill pipe if necessary) to kill the blow out. The OD is approximately tool joint size, permitting it to pass through preventers, gates, strippers, etc. Mud is saved and the rig floor is kept clean by closing the Lower Kelly Cock when the kelly is broken out to add drill pipe. A quarter turn operates the hex '\vrench handle from full open to full closed. The Lower Kelly Cock should not be used partially closed for flow control or throttling. High pressure shut off and free turning are assured by the ball valve design. Positive shut off (even at low pressure) is provided by the unique seats which are rubber molded to brass. The rugged design readily handles the high torque and impact loads of high speed drilling. SPECIFICATIONS AND PARTS

The Shaffer Type 55 Upper Kelly Cock is an advanced design that gives maximum protection to the rotary hose by providing a high-pressure, quick-acting, shut-off valve above the kelly and thus insuring control should the well flow in through the drill pipe. It is completely streamlined with no protruding parts. The plug of the Type 55 Upper Kelly Cock is made of forged steel and is resistant to corrosion and cementing action by the mud. It is equipped with two rubber "O" rings seals placed as shown in Figs. 72 and 73 which seal effectively as the plug rotates in the body. At the top and bottom of the plug are manganese bronze insert seals, each with rubber seals and compression rings. The insert seals are carefully molded to conform to the surface of the plug as indicated in Fig. 74. When the Kelly Cock is open there is direct flow through the plug. There is no pressure on the body when it is open or closed, the pressure being always on the seals and the plug. With the insert seals both above and below the plug, pressure is not Fig. 73 Tvpe 55 Upper Kelly only sealed off from Cock showing plug and insert seals for sizes below but in case 2%" to 4!1", inclusive circulation should be started down through the Kelly Cock when it is in closed position there is no danger of cutting out the insert seals and the body.

FULL OPENING LANDING HEADS (Patented}

MODEL KS AND MODEL KD HEADS casing string and internal bore of the head. The spring :steel snap ring retains the packing unit in the bore of the head so that any head above may be removed without lo:sing the pressure-tight seal. In both models, the slips are of ample length to insure uniform weight distribution, and the slips are adequately backed-up by the taper in the bore of the head to provide full slip support. The slip and bore tapers are properly desgined to prevent the slips from sticking and to prevent collapse of the casing string.

Model KS and Model KD Heads are an improved design with no threads in the internal bore to hold the packing unit in place, or to effect the seal between casing rings. In both models, the slips and packing units are the same and are interchangeable, size for size. The packing unit consists of a lower steel ring, a solid rubber packing ring, an uppe1· steel ring, a spring steel snap ring, and cap screws. The rubber packing ring fits between the steel rings, and is compressed by tightening the cap screws, thus packing off between the

MODEL KS HEADS Model KS Heads (Fig. 76 and Fig. 77) are designed for installations where maximum working pressures do not exceed 2000 PSI. The packing unit seats directly upon the slips as shown in Fig. 76. Although the load induced by the well pressure is transferred to the slips, this is a minor factor in low pressure ranges and is not detrimental.

MODEL KD HEADS Fig. 76 Full Opening Model KS Single Flange Landing Heod

The Model KD Heads (Fig. 78 and Fig. 79) should be used on those installations where the working pressures exceed 2,000 pounds per square inch. To relieve the load induced by the well pressure from being transferred to the slips the packing unit seats on a beveled steel snap ring supported in a recess in the bore of the head as shown in Fig. 78. This construction greatly reduces the collapsing load on the casing.

SINGLE FLANGE AND DOUBLE FLANGE DESIGNS

Fig. 77 Exploded View of Model KS Pocking Unit

Both the KS and KD Heads are available in two typesthe Single Flange (as shown in the KS Head of Fig. 76), and the Double Flange (as shown in the KD Head of Fig. 79). The Single Flange Heads (whether KS or KD) have a bottom connection for either slip-over and weld, or with male or female threads. Both types have two 2" outlets in the body-overall height is approximately 17" for both KS and KD. The Double Flange Heads (whether KS or KD) are similar, but with flanges both top and bottom as shown for the KD Head in Fig. 79. They have 2" outlets and an overall height of approximately 17"-but may vary slightly, depending upon the thickness of the flanges used in the various API ratings.

FULL OPENING LANDING HEADS MODEL KU HEADS The Model KU Heads are designed so that there are no threads or snap rings to hold the packing unit in place. The weight of the casing holds the slips and packing unit down and cap screws hold and compress the packing rubber to effect a seal. The slips are of ample length to insure uniform distribution of the gripping pressure and wickers on the outside prevent

their downward movement and collapse of the casing. Model KU Heads are furnished with either of two types of slips and packing units-Unitized Slips and Packing Units or Automatic Slips and Packing Units. They are interchangeable with each other and both can be run through blowout prevention equipment or set in the conventional manner.

UNITIZED SLIPS AND PACKING UNITS

The Unitized Slips and Packing Unit shown in Fig. 81 provides in one assembly a complete means for supporting and packing off a casing string as indicated in Fig. 80. The wrap around construction enables the unit to be run through blowout equipment. When run through blowout equipment, the casing is landed lowering the unit into the

bowl of the head below. This effects a partial seal. The blowout equipment is then raised and the packing in the head is expanded to effect a complete seal by tightening the cap screws. When the pack-off is completed, the blowout equipment is lowered and drilling operations resumed. Fig. 80 Full Opening Model KU Double Flange Landing Head with Unitized Slips and Packing Unit

AUTOMATIC SLIPS AND PACKING UNITS

The Automatic Slips and Packing Unit is used with the Model KU Heads in the same manner as the Unitized Units. They are particularly advantageous when running the slips and packing unit through blowout equipment since the landing of the casing with this unit is accomplished with complete control as it is not necessary to raise the blowout equipment from the body of the Model KU Head. The Automatic Slips and Packing Unit is similar to the Unitized Slips and Packing Unit except that the four slip segments are made with inner and outer shells with the cap screws attached to the inner shell as shown in Fig. 82A. With the Automatic Slips and Packing Unit the automatic sealing element is actuated entirely by casing weight and requires no additional adjustment or make up after the unit is landed in the bowl of the Model KU Head. While the casing is under tension, the Slips and Packing Unit is wrapped around the casing, latched and lowered into the casing head. With the tapered surface of the outer shell of the slips en-

gaging the bowl of the head and the inner shell of the slips engaging the casing, the tension on the casing is relieved. The inner slips engaging the casing then move downward with the casing until the mating shoulders of the outer and inner shells of the slips contact and cause the slips to support the weight of the casing and keep it from further downward movement. The slight downward movement of the inner shell of the slips pulls down the upper steel ring through the medium of the cap screws and thus compresses and expands the packing rubber to effect a tight seal. No further tightening of the cap screws is ordinarily required.

UNITIZED WELLHEAD The Unitized Wellhead is a complete wellhead in one body. Continuous blowout preventer protection is assured. Surface casing is cemented and this head is installed. Blowout preventers are then installed and remain in place until after the tubing hanger is run, sealed, and locked in place. Rig time is saved because it is not necessary to break off the blowout preventer and add a casing landing spool. Crew safety is improved by eliminating accidents which occur when the blowout preventer is removed and a casing landing spool installed. This operation requires heavy items to be handled in awkward conditions. One ring joint is eliminated in the wellhead because the surface head, the oil string head, and the tubing head are one continuous body. A shorter wellhead is the result of one continuous body. An independent landing shoulder is provided for each casing hanger and for the tubing hanger instead of having all the casing and tubing strings supported by a single shoulder as is done in a "stacked" assembly.

Fig. 84 Unitized Wellhead with Threaded Casing and Tubing Suspension Hangers

-casing hangers are available for almost any combination of casing strings. Normally casing is landed on a threaded (or mandrel type) hanger as shown in Fig. 84 and in Fig. 88 on page 4322. However, a slip suspension hanger can be used if the casing sticks before the desired landing point is reached as shown in Fig. 85 and in Fig. 89 on page 4322. Both of these hangers are run through the blowout preventers. The casing packing unit is normally run after the hanger has been landed and the seals are energized by closing the locking screws. A test port in the head connects to the space between the two seals so that the pack-off is conveniently pressure tested. Tubing hangers are available for various sizes of tubing and for multiple completions. These hangers can also be equipped to accommodate submersible electric pumps, gas lift equipment, hydraulic bottom hole pumps, etc. Tubing sealing elements are built into the tubing hanger and the weight of the tubing normally establishes an initial seal. The locking screws are run in to further insure a positive seal and to hold the tubing down while the blowout preventer is removed from the head.

A tubing seal flange is mounted on the top of the body and the Xmas tree is installed above the seal flange.

ELECTRIC FEED-THROUGH MANDREL AND TUBING HANGER (Patented)

The Shaffer "Feed-Through" System fills an important need for a safe, pressure-tight method of running high-voltage electrical conduit into a well for operating electrically-driven down-hole submersible production pumps and similar equipment. It consists, essentially, of a dual-string Hanger in which one opening is used for suspending and packing off the production string, and the other opening is used for carrying the electrical service into the well. The electrical conductors are sealed into a cylindrical "potted" lVIandrel using a specia!Iyselected dialectric material that both insulates the leads and prevents any pressure leakage internally through the lVIandrel. The outer circumference of the lVIandrel is packed off much the same as a tubing string, using high-pressure seal rings that prevent any leakage of well pressure between lVIandrel and Hanger body. RIGID SUPPORT

The "Feed-Through" lVIandrel itself is held firmly in place by a threaded section that screws into the Hanger -which, in turn, is held firmly in place in the wellhead by a conventional lock-screw design so that no internal well pressures can move the lVIandrel or cause destructive "working" of the sealed-off areas. Also, no mechanical movement to which the outside of the Hanger may be subjected can affect the pressure-tight seal. FIELD PRESSURE-TEST CONVENIENCE

A double set of seals is provided on the lVIandrel-one set packs off in the Hanger itself and the other in the top flange-so that the area sealed off by the API ring can be quickly and easily pressure-tested at any time.

NO LOSS OF BLOWOUT PREVENTER PROTECTION

Another important advantage engineered into the Shaffer "Feed-Through" System is that during landing and completion operations, the "Feed-Through" lVIandrel, Hanger and the production string can all be run through the blowout preventer and landed in place while maintaining complete control over the well.

Fig. 92

Double-Plug Mandrel (with protective rubber boot) for Feed-Through System

In both designs the connectors are polarized to insure proper alignment, and each connector is equipped with an internal seal to prevent any pressure leakage into the plug-in area of the connector. FULL ELECTRICAL COMPATIBILITY

1WO DESIGNS The Shaffer "Feed-Through" system is available with ;wo different Mandrel designs. In the "Single-Plug" deiign (Fig. 91) the electrical leads coming into the top )f the lVIandrel are integral with the Mandrel itself, vhile only the connections at the bottom of the lVIandrel tre "plug-in" type, locked in place by a threaded ring. :n the "Double-Plug" design (Fig. 92), plug-in connec-

The electrical connections and the voltage and amperage capacities in the "Feed-Through" lVIandrel are compatible with standard down-hole submersible pump design to insure meeting the necessary electrical requirements. This assembly also meets the requirements for permanent installation on urban drill sites where it is particularly important that the well be protected against all explosion and fire hazards.

TYPE 55 TUBING HEADS WIDE SELECTION OF DESIGNS

CONVENIENT METHOD OF DESIGNATION

Shaffer Type 55 Tubing Heads are available in a wide range of types and designs to meet the many and varied conditions encountered in producing oil wells. They have been developed through years of experience and with close cooperation with leading oil operators. When used with other Shaffer equipment they provide safety and flexibility of operation that insures maximum economy and simplifies well maintenance. Shaffer designs are particularly adaptable to high pressure production, and emergencies that may arise while running tubing can be readily handled. Even with the highest well pressures, tubing depth can easily be changed without killing the well, and tubing can be pulled with complete safety when the well is otherwise properly equipped.

To facilitate ordering the various types of tubing head designs which Shaffer manufactures, the complete tubing head is divided into its various component parts -(A) the type of Body, and (B) the type of Hanger. These various designations are explained in greater detail below. INSTRUCTIONS FOR ORDERING

All Shaffer Tubing Heads are furnished with A.P.I. Ring Joint Flanges unless otherwise specified. In ordering, specify type of Body ( S or L), and the type of Hanger desired. In addition, give size of casing, tubing, gas outlets and top connections, and whether flanged or screwed lower connection.

TWO TYPES OF TUBING HEAD BODIES

Bodies for Shaffer Type 55 Tubing Heads are available in two different heights. The "Short" Body (Type S) has an over-aII height of 9" and is ideal where maximum compactness is essential. The "Long" Body (Type L) has a minimum over-an height of 131/z" or more, depending upon the size and design, and provides maximum adaptability to a wide range of installation requirements.

Fig. 94 Type S Body

The Type S Bodies are available with double flange::: only as shown in Fig. 94, while the Type L Body is available in both single and double flange designs a< shown in Figs. 95 and 96. In aII types a standard tapeI of 3" per foot is used to insure proper wedging actior: without sticking the Hangers.

Fig. 95 Type I. Body-Single Flange

Fig. 96 Type I. Body-Double Flange

LOCKING ARRANGEMENT

Shaffer Type 55 Tubing Head Bodies incorporate a locking arrangement for holding tubing in place, as shown in Fig. 97. In this arrangement, the upper flange is drilled and tapped for locking screws that can be tightened and released externally without disturbing the connections above.

TYPE 55 TUBING HEADS TYPICAL TUBING HANGER DESIGNS

Type 55 Tubing Heads are made for production hook-ups of all types whether located on the derrick floor or in the cellar. They provide for easy removal of the Christmas tree without disturbing the tubing. Some types can be used as spiders and all types permit changing the packing with maximum ease and safety. Although the complete line of Type 55 Tubing Heads is too extensive to ill ustratc here, this page shows some of the more popular types. TYPE A TUBING HANGERS

The Type A Tubing Hangers provide solid Christmas tree connections that can easily be removed without disturbing the tubing. Locking screws are used for holding the tubing hanger in place against well pressure-an arrangement that has several advantages. It Fig.98 permits locking the tubing Type A Tubing Hanger hanger in place from the outside by means of the locking screws, and when the tubing is landed through a control gate it is unnecessary to remove the gate from the top of the tubing head to lock it in place. When removing the tubing either under pressure or otherwise (with adequate blowout equipment installed on the tubing head) it is only necessary to back off the locking screws to permit the tubing to be pulled from the well with safety. As illustrated in Fig. HS, the Type A Tubing Hanger is equipped with two rings of hydraulic packing, and seats and packs off against the tapered bowl of the Tubing Head Body. TYPE AJ TUBING HANGERS

The Type AJ Tubing Hanger is a threaded suspension hanger for use where known field conditions permit removal of the blowout preventer and installation of the Christmas tree before washing in or completing the well. When equipped with a back pressure valve it retains well pressure during the operation of preventer removal and tree installation. The back pressure valve seals off well pressure up to the tested rating of Fig. 99 the tubing and affords a verType AJ Tubing Hanger tical run that permits passage of A.P .I. drift mandrels. Removal under pressure is accomplished by normal lubricator operations.

TYPE C TUBING HANGERS

The Type C Tubing Hanger provides means for raising and lowering the tubing while maintaining a continuous seal. As shown in Fig. 100, the Type C Hanger incorporates two rings of hydraulic packing for sealing off against pressure leakage against the Hanger and the bowl of the Tubing Head Body, and also incorporates the packing element for sealing off Fig. 100 around the tubing string which TypeCTubingHanger is suspended through the Hanger and supported by a top flange. A packing gland with bolts provides means for tightening and loosening the packing pressure around the tubing string.

TYPE W ANNULUS TUBING HANGERS

The Type W Annulus Tubing Hanger is designed to suspend tubing in an off-center position so as to provide for a threaded opening into the annulus between the tubing and casing strings through which wire line equipment can be run into the well as shown in Fig. 101. This arrangement greatly facilitates running such equipment as pressure bombs, Fig. 101 temperature gauges, depth Type W Annulus gauges, and other similar Tubing Hanger tools into the well for measuring and recording production data. When not in use, the opening is securely closed by means of a valve or a threaded plug. The size of the tool that can be run through the annulus opening depends, of course, upon the sizes of the tubing string and the tubing head. However, for each combination of sizes the annulus opening is engineered at the proper angle to permit the maximum length of tool to be lowered into the well. Since each Type W Annulus Tubing Hanger is individually engineered to meet the particular requirements of each production installation, it is recommended that a sketch or drawing be submitted showing the general type of arrangement desired, the size of the valve to be fitted to the riser nipple, the casing and tubing sizes.

TYPE 59 TUBING HEADS The Shaffer Type 59 Tubing Head is constructed with a straight packing bowl to prevent the bowl from being damaged while running tools or tubing, and with a 45° shoulder to support the tubing hanger. The sealing element seals against the straight portion of the bowl and the tubing weight is supported by the shoulder located below the sealing area. Fig. 102 The sealing elements Type 59 Tubing Head will maintain the seal even when subjected to eccentric loads which are encountered in dual tubing strings. This makes it advantageous for dual installations and the Type 59 Tubing Head can be used with one or two strings in

addition to the production string when the prope hanger is employed. When used with other Shaffe equipment these heads provide safety and flexibilit of operation that insure maximum economy and sirr plify well maintenance. The upper flange of the Type 59 Tubing Head i drilled and tapped for locking screws that can b tightened and released externally without disturbin the connections above. The tubing head is equippe with two outlets that are studded for flange connec tions. The design is particularly adaptable to high pref sure production and emergencies that may arise whil running tubing can be readily handled. Even with th highest well pressures, tubing depth can easily b changed without killing the well, and tubing can b pulled with complete safety when the well is othei wise properly equipped. Like the Shaffer Type 55 Tubing Heads the Shaffe Type 59 Tubing Heads are furnished in two bod types: Type S and Type L.

TYPE 59 TUBING HANGERS TYPE A TUBING HANGERS

TYPE AJ TUBING HANGERS

The Shaffer Type A Tubing Hanger combines maximum strength with a continuously energized packing unit which consists of two floating packing rubber rings separated by a steel spacer ring. Beneath Fig. 703 the lower packing rubber is a Type A Tubing Hanger steel support ring held in place by a retaining ring. The weight of the tubing compresses the packing rubbers to effect a seal and locking screws actuated from the exterior of the tubing head retain the hanger in the sealing position. The Type A Tubing Hanger thus provides solid Christmas tree connections that can easily be removed without disturbing the tubing. When removing the tubing, either under pressure or otherwise (with adequate blowout equipment installed on the tubing head) it is only necessary to back off the locking screws to permit the tubing to be pulled from the well.

The Shaffer Type AJ Tul ing Hanger is a threaded sm pension hanger for use wher known field conditions perm removal of the blowout pri venter and installation of th Christmas tree before wasl ing in or completing the wel When equipped with a bac pressure valve it retains we pressure during the operatio of preventer removal and trE installation.

TYPE H TUBING HANGERS

Fig. 105 Type H Tubing Hanger

The Shaffer Type H Tubing Hanger provides a means of raising or lowering the tubing string under pressure while maintaining a continuous seal. It is made with wrap-around construction which enables the hanger to be easily placed around the tubing string. The tubing hanger consists of a lower steel ring, a split rubber packing ring, an upper steel ring and cap screws all held together as a unit. The split rubber packing ring seals against the packing bowl as well as the tubing. The hanger is held in place and is sealed by the locking screws.

TYPE KS TUBING HANGER FOR TYPE 59 HEAD

Fig. 106 Type KS Tubing Hanger

The Shaffer Type KS Tubing Hanger is provided with a threaded connection for supporting the production tubing string as well as slips and packing elements for supporting and sealing off one or two additional smaller tubing strings. The slip suspension eliminates the necessity for cutting nipples when landing the smaller tubing strings. In landing the smaller strings, the tubing is run through the tubing hanger

body with the packing gland in place. The bores of the packing gland and hanger body are sufficiently large to freely pass the coupling diameter. At the landing depth the packing gland is unbolted and lifted up to permit installation of the slips and the split packing unit. Replacing the packing gland effedively seals the tubing within the hanger. The Type KS Tubing Hanger is available in a wide variety of tubing combinations and is adaptable to meet Christmas tree requirements.

ANNULUS TOP FLANGES TYPE T TUBING HANGERS

The Type T Tubing Hanger as shown in Fig. 107 supports the tubing in either a male, female or studded flange, or a flanged spool, which rests on the top flange of the Tubing Head Body and is sealed by an A.P.I. ring. Fig. 107 The supporting flange is Type T Tubing Hanger ordinarily furnished with ,ither a :3,, or 4,, line pipe conne'ction but other ar·angements are available.

Fig. 108 Annulus Top Flange

The Annulus Top Flange for use with Type 55 and Type 59 Tubing Heads provides room for a threaded opening into the annulus between the tubing and casing strings, through which wire line equipment can be run into the well. Each Annulus Top Flange is individually engineered to the production installation. Write for complete details. ·

AUXILIARY SECONDARY SEALS

Fig. 109 Auxiliary Tubing Head Seal

showing casing guide insta/led

This Seal, for use with the Shaffer Type 55 and Type 59 Tubing Heads, is designed as an auxiliarv seal to the seal in 'the casing head. This effects a pressure cross-over due to the reduced area, thus relieving the pressure on the API ring between the cas-

ng and the tubing heads. The seal around the pipe is provided by a graphited sbestos ring that is squeezed against the pipe by lastic: packing introduced through a check valve on he periphery of the bottom flange of the tubing head. 'his construction permits repacking the seal at any ime during the life of the well. A testing port per1its testing between the casing head seal and the uxiliary seal in the tubing head.

BACK PRESSURE VALVES

The Shaffer Type A Back Pressure Valve acts as a safety precaution while installing a Christmas tree, and is also used for maintenance or removal of parts of a tree. It is furnished in sizes ll/z" 2" and 21/:z", for pressures up to 10,000 PSI.

FLO-SEAL GATE VALVES For Mud, Water, Oil and Gas Service

Line pressure seals the valve. Refer to Fig. 127. Flow line pressure drives the Piston Seat toward the vacuum space which is created by the Gate Guide. The gate end of the Piston Seat is smaller than the rear end so that the psi sealing force between the seat and gate is approximately double the line pressure. Prolonged valve life is assured because the upstream seat continues to seal if the downstream seat is cut out. Experience shows that any gate valve which is opened and closed repeatedly against high pressure, abrasive fluids will cut out the downstream seat first but leave the upstream seat relatively undamaged. Minimum wear and easy operation are obtained because the line pressure forces the Piston Seats against the gate tight enough to seal but no tighter. Positive wiping is assured by the Piston Seats bearing on the gate constantly while the valve is being opened or closed. The seats are protected because the piston action holds them tightly against the gate at all times. This prevents sand and other foreign material from getting between the seats and gate, and it also minimizes corrosion between the seats and gate. Handles mud, sand, and cement because the Piston Seats seal the flow line fluid out of the valve body when the valve is fully open or fully closed. If desired, a drain outlet can be installed in the bottom of the body. Then (with the valve fully open or fully closed) the drain can be opened and the body flushed through the grease port and out the drain. Fig. 126

"Flo-Seo/" Gate Valve

The fully skirted Gate Guide minimizes the amount of flow line material which enters the body. Precharging the body with either grease or water is a further aid to keeping flow line material out of the body while opening or closing the valve. The floating gate assures perfect alignment with the seat and minimizes chances of stem breakage. A "T" shaped gate bushing fits into the top of the gate and is threaded on to the valve stem. This allows the gate to float and align itself with the valve seats.

Repairs are simple enough that any roughneck can make a rapid, in line field repair. This valve was designed for oilfield service, to be easy to understand, and eliminate close tolerance fits. The through-conduit round-bore eliminates turbulence and collection of foreign matter because there are no pockets or cavities. A back seat on the stem allows the stuffing box to be repacked while the valve is in service. The stem is 410 stainless steel which is corrosion resistant and heat treated for high strength. The thrust bearings are prelubricated but a grease fitting is provided so that additional grease may be applied if necessary. The bearing housing is sealed to keep water and dirt out and the grease in. Holds pressure from either direction because both

seats are identical. Each valve is tested to rated working pressure with the gate closed and one encl open to atmosphere. It is then turned around and tested on the other end. These tests are performed with no grease in the body and a valve must hold in both directions to be accepted. Grease is put in the body only after these tests are completed. (The 15,000 psi model holds pressure in one direction only.) The seats and gate are permanently lubricated with a baked-on Molybdenum Disulfide lubricant. Actually no further body lubrication is required for most services but each valve body is greased as an added precaution. Also, the valve body will fill with flowlinE fluid in service and packing the body with greasE helps to hold this fluid out as it may contain abrasivE or corrosive materials. Temperature limits for Flo-Seal Valves are -20 tc 250° F.

Hf LO-SEAL u GA TE VALVES HYDRAULIC OPERATORS

Shaffer "Flo-Seal" Gate Valves can be equipped \vith Hydraulic Valve Operators with manual override. The Hydraulic Operator will operate efficiently at 1000 PSI for all Valves rated up to 10,000 PSI Working Pressure. The unit is activated by a totally-enclosed pressure system and provides ne-w efficiencies for controlled valve operation. The Hydraulic Operator may be used in any location, including under-water installations, and is particularly useful on mud line manifolds. "Flo-Seal" Valves equipped with the Hydraulic Operator may be manually closed in the event of a hydraulic system failure. They also may be locked manually in a closed position (in addition, note the automatic locking designs shown on the facing page). Shaffer "Flo-Seal" Valves with Hydraulic Operators require no special installation procedures. The Gates and Seats are the same as in the conventional "Flo-Seal" Valves shown on pages 4336 through 43:39. The Hydraulic Operating unit is similar in principle to that used for many years in Shaffer Hydraulic Blowout Preventers, and is both positive and trouble-free. Hydraulic pressure applied to the double-acting piston moves the attached valve stem up or down for opening or closing the Gate in the Valve, with ample opening and closing ratios to assure quick and positive operation.

GATE V Al VES AUTO-LOCK HYDRAULIC OPERATOR

Shaffer "Flo-Seal" Valves provide entirely new standards of efficiency and reliability when equipped with the Auto-Lock Hydraulic Operator. This device automatically locks the gate in a closed position without secondary systems or mcmual operation. It stavs locked indefinitelv without need for hYdraulic pressures, operating spri;gs or other mecha;1ical auxiliaries, yet ·it releases immediately whenever desired. To open the valve, simply apply hydraulic pressure in a gate-opening direction and the lock releases automati-

cally. This simple, positive, self-actuating device is completely self-contained. When the gate reaches its closed position, locking elements are automatically forced into a locking recess. A special coil-type spring then maintains the necessary sealing force to hold the locking elements and gate in a locked position without need for hydrnnlic pressure or other mechanical forces. The highest line pressures cannot force the lock open. Whenever it is desired to open the gate, simply apply hydraulic pressure in a gate-opening direction to the operating piston and the hydraulic pressure automatically unlocks the mechanism.

Fig. 131 "Flo-Seal" Gate Valve with Auto-Lock Hydraulic Operater

The Auto-Lock Hydraulic Operator is designed for use with 1500 PSI accumulator systems-the pressure rating recommended for longest life and minimum maintenance. However, 3000 PSI systems can also be used without modifications and without need for regulator valves. Shaffer "Flo-Seal" Valves, equipped with the Auto-Lock Hydraulic Operator, are especially adaptable to remote locations such as underwater installations, mud line manifolds and gathering stations.

AUTO-LOCK HYDRAULIC OPERATOR WITH MANUAL OVERRIDE

The Manual Override is an auxiliary feature to the Auto-Lock Hydraulic Operator. In the event of a failure in the hydraulic system, the manual override provides mechanical closing. The mechanism forces the locking elements into the locking recess. Hydraulic pressure must be applied to release the locking device, after first releasing the manual override.

ADJUSTABLE CHOKES (Patented}

The adjustable flow bean was pioneered by the Shaffer organization. Adjustable Flow Beans incorporate unique and far-reaching advancements that make them ideal not only for controlling the flo\v of fluid passing through a line, but also for regulating the pressure and the rate of flow with extreme accuracy. This highly-accurate control and regulation is secured by an orifice through which is moved a tapered of fluted tip. The tip is moved in and out of the orifice by means of a hand-wheel and the annular opening between the tip and the orifice at any setting is indicated on a gauge. The orifice is designed on the principle of a Venturi tube which incorporates a taper at both the entrance and discharge sides as indicated in Fig 136. This important feature permits the fluid to flow through the orifice with minimum turbulence and emulsification. Where the orifice is tapered only on the entrance side and is a straight tube on the discharge side (as shown in Fig. 137), the fluid emerging from this straight bore is not controlled as it flows into the discharge line. This uncontrolled flow causes eddy currents, increases flow turbulence and tends to emulsify the fluid. In the Adjustable Flow Bean the fluid is guided into the orifice by the tapered inlet, and on the discharge side is guided out again by the tapered outlet. This tapered outlet controls the fluid flow, bringing it gradually to the full diameter of the discharge pipe without the turbulence and emulsification that is caused by a straight orifice tube. For this reason, a greater volume of fluid will pass through an orifice of given area in the Adjustable Flow Bean than through the same area in other designs.

IMPORTANT ADVANTAGES The double-tapered orifice design described above makes a number of important savings. Less emulsification of the fluid means less treating costs for separating water from the oil and greater handling efficiency in production and refining operations. In addition, another exclusive advantage is that Adjustable Flow Beans may be connected in the hook-up so that the flow is either toward or against the tip-an advantage that is not practical with the straight discharge type of orifice. This feature. simplifies installation and permits a wider versa ti 1it y in installing Flow Beans. They can be placed at any convenient location, and in Christmas tree hook-ups they are usuallv located to function as ells on· each lead line.

the adjustable feature provides a correct size of opening without breaking the flow of oil or gas, Adjustable Flow Beans permit the accurate control of back pressure that is necessary to secure the lowest oil-gas ratio and the most efficient production. Also, proration of production is secured most accurately by using the Shaffer Flow Bean. With this unit the amount of oil being produced can be kept to the allowable with the least amount of variation. In drilling as well as in production operations the Adjustable Flow Bean makes possible higher efficiency and greater accuracy of control. This Flow Bean is used extensively for holding a back-pressure on the circulating fluid ·while drilling and this application is especially important in pressuredrilling where such a device is essential to control the overflow. The Adjustable Flow Bean is particularly adaptable to use on choke line drilling manifolds.

IMPORTANT CONSTRUCTION FEATURES Adjustable Flow Beans are built throughout for heavycluty service. The important advantages of their unique double-tapered orifice design has already been explained. This orifice is screwed into the body as indicated in Fig. 135 and is readily replaceable in all types of Adjustable Flow Beans. As shown in Fig. 135 the packing unit, on the stern that carries the adjustable tip, is held in place by a gland which is tightened by means of hvo hinged eye bolts. These hinged eye bolts permit maximum speed and convenience in serviceing the packing unit. Where the stem passes through the body a bronze bushing is inserted to prevent steel-to-steel contact and to prolong the life of the stem. Whenever necessary, this bronze bushing can be quickly replaced, thus safeguarding the body against wear. Being of bronze, the bushing will not corrode and assures maximum ease and friction-free operation in adjusting the orifice opening. A similar bronze bushing, which is threaded to fit the stem, is inserted in the yoke to minimize friction and resist corrosion. The. tip is attached to the stem so that it can be readily replaced whenever desired, yet will not loosen in service. A self-locking ring nut automatically grips the tip as it is tightened against the stem, thus holding it firmly against vibration and movement on the stem. As can be seen in Fig. 135 all Adjustable Flow Beans are equipped with a locking handle which firmly holds the tip in whatever position it is set. When the desired tip position has been obtained, a quick cinch on the locking handle holds the hand wheel against rotation and assures the exact setting being maintained. Another convenience is that all Adjustable Flow Beans have a tapped opening in the body to which a pressure gauge can be readily attached for checking flow pressures. In addition to the Flow Beans shown, they can also be furnished in a Cross Type and a Side Outlet Type to meet varying requirements.

ADJUSTABLE TO ANY REQUIREMENTS Since pressure varies during life of a well and from well to well, the Adjustable Flow Bean permits meeting changing conditions ~with the greatest of ease and efficiency. The flow can Fig. 735 only be kept at its most proAdjustable Flow ductive point by constantly Bean with A.P.I. Ring Joint Flangeschanging the opening through Type 65 which the fluid passes. This applies to wells on gas-lift as well as those flowing by formation pressure. It has also been found that in many pumping wells the application and control of back-pressure frequently arrests decline and increases recovery from the well. Since

Micro Tip

Fig. 140 Fluted Tip

All valve tips are regularly made from selected tool steel properly hardened for maximum resistance to abrasion. Tips are also available from specially selected materials such as Tungsten Carbide, Stellite and 17-4 PH Stainless Steel, on special order.

WIDE SELECTION OF TIPS FOR VARYING APPLICATIONS In addition to the standard conical tip there are also micro tip and fluted tip-all of which are interchangeLble in the same flow bean body. All tips are made of .pecial alloy steel and are heat treated to obtain the rreatest resistance to wear and to give maximum ervice. • Conical Tip: Unless otherwise ordered, all Shaffer ;hokes are furnished with a conical tip as illustrated 1 Fig. 138. This tip gives very accurate control of

t

flow through the orifice and is machined to very close tolerances with a uniform taper from the point to the maximum diameter of the tip . o Micro Tip: On special order, all Shaffer Chokes may be equipped with the Shaffer Micro Tip as illustrated in Fig. 139, which provides an equal increase in opening diameter for each turn, or fraction of turn, of the wheel throughout the entire travel of the tip. This permits great accuracy in controlling small openings and also gives a flow more nearly that of a perfect venturi tube than is secured by the conical tip. These tips are widely used for all kinds of close control of volume and pressure.

• Fluted Tip: This tip (Fig. 140) is designed especially for high pressure water flooding operations and similar flow control where close adjustment within maximum diameter orfice results in excessive line cavitation, vibration and chatter. The straight portion of the tip fits closely within the bore of the venturi insert and thus adds support to the extended valve stem, effectively reducing or eliminating exce:;;sive chatter. The fluted ports are calibrated so that one port is larger than the other two ports and thus the greater flow and pressure through the larger port assures constant bearing of the tip within venturi orifice. All of the flutes end below the sealing area so very close regulation can be obtained from the Fluted Tip. ORIFICE DIAMETERS FOR CHOKES

Shaffer Adjustable Chokes are normally equipped with the largest size orifice available for a given size Choke, as indicated in the table below ..•

POSITIVE CHOKE

TYPE 34 Many operators install Shaffer Type 34 Adjustable Chokes and use the adjustable feature to determine the correct orifice diameter for a fixed orifice choke. The Type 34 Positive Choke features a bolted blanking-off cap which is substituted for the yoke assembly of the Type 34 Adjustable Choke. The venturi insert is bored to the corresponding insert of the fixed orifice choke. Available in sizes 2" through 6", \Vith :flanged or screwed connections, and in working pressure ratings of 1000 PSI through 10,000 PSI. Fig. 145

Positive Choke--Type 34

POSITIVE CHOKE

TYPE 65 The Type 65 Positive Choke is similar to the Type 34 Positive Choke above, but features a clamp yoke connection to permit quick choke changes. This design can also be readily converted to the adjustable type by using a clamp yoke assembly. The tapered chokes fit within the tapered bore of the venturi insert and are easily removed for replacement. The Type 65 is available in sizes 2" through 6", with flanged end connections only. It can be furnished in rated working pressures ranging through 10,000 PSI with either ASA or API flanges.

DAMPING SUB

'----0

THE SHAFFER DAMPING SUB is especially engineered to prolong bit life, reduce drill collar fatigue and smooth out vibration and impact loads. It is made up on the string immediately above the bit, and drilling weight is applied to the bit through the shock absorbing element in the tool. ABSORBS BIT VIBRATIONS: In rough drilling areas bit cones left in the hole and cracked drill collars are common experiences. In these areas, bit vibration is usually severe enough to vibrate the whole drill string and frequently, the complete rig. Installation of a Damping Sub reduces these problems by absorbing the intense vibrations. Downhole studies without a Damping Sub measured weight variations in normal drilling at about 1.25 to 1.50 times the weight on the bit with maximum variations in excess of 3.5 times the weight on the bit. Bit bearings must withstand these tremendous weight variations, and it is well known that heavy vibrations shorten bit life drastically. Na tu rally, the bits will fail almost immediately after the bearings collapse.

Fig. 149 Damping Sub

LESSENS FATIGUE FAILURES: Cracked drill collars are the result of fatigue. Fatigue failures occur under the action of repeated stresses and are the result of slip occurring along certain crystallographic directions. This slip is accompanied by local crystal fragmentation which ruptures the atomic bonds and leads to the formation of minute cracks which soon become visible cracks. Installation of a Dampening Sub rP-

(Patented)

duces the weight variations and thereby gives a more constant loading on the bit bearings and the drill collars. RELEASE HEAT IN SHOCK ABSORBER ACTION: Heat is the only possible result of the Damping Sub shock absorber action. Any device which is to successfully perform this task must convert the mechanical vibration energy to heat and then dissipate the heat to the mud. Therefore, the Damping Sub must be capable of functioning at a temperature higher than that of the bottom-hole mud. The shock absorbing element is made from stainless steel wire which has been woven into a cloth-like mesh. This mesh is then compressed to the required shape in a special hydraulic press. As a load is applied to the element, the length decreases and the radial thickness increases, which gives the element its spring action. As the wires rub against each other, they convert the vibrational energy into heat and dissipate this heat through thei"body of the Damping Sub to the mud stream. TRANSFERS DRILLING TORQUE: Drilling torque is transmitted through heavy splines which permit the upand-down movement in the tool. Both the elements and the splines are enclosed in an oil bath and a floater compensates for thermal expansion of the oil. EXTENDS BIT LIFE: Since longer bit life means fewer round trips, the main advantage to using the Damping Sub is faster and less expensive drilling.

SHAFFER-WAGGENER BUMPER SAFETY JOINT

(Patented)

Here in a single tool-made only by Shaffer-are combined the two best methods of protection against pipe stuck in the holea Bumper Sub that jars clown automatically, and a quickreleasing Safety Joint. The Shaffer-Waggener Bumper Safety Joint is specifically designed to be run directly in the drill string and is built to take all the vibration and torque of modern high speed, deep drilling operations. For both of its applications the tool has unique advantages over single-purpose units available. Torque loads are transmitted in either direction through 3 drive keys, not threads. Construction of the tool thus prevents wobble and rotational backlash. Large through bore provides for full circulation and permits passage of wire line tools. Unique disc type spring permits high tonnage loads without tripping, and the tripping mechanism holds solidly until the pre-set tripping weight is placed on the tool.

JARS AUTOMATICALLY To use for jarring, it is only necessary to slack off weight of approximately 2000 feet of drill pipe onto the tool, thus releasing the tripping mechanism and striking a sharp downward blow. Raising the string automatically re-sets the tool for another blow, and blows can be struck as fast as the pipe can be raised and lowered. The tool provides an instant means for jarring through bridges, tight spots or key seats . . . jarring loose when drill pipe freezes . . . and pulling off bottom with a balled up bit. RELEASES QUICKLY As a safety joint, the Shaffer-Waggener Bumper Safety Joint is quickly released by tripping the tool and applying reverse torque as the string is slowly raised. Just one sixth turn of the drive keys rotates them into an unlocking slot so that complete release is obtained as the string is raised. Release and reengagement can be effected as often as desired.

To release the ShafferWaggener Bumper Safety Joint from stuck drill collars, it is only necessary to first trip the tool by applying the required weight of drill pipe. This positions the drive keys as shown above so that -by a pp/ y i ng reverse torque and slowly raising the drill string-the keys are rotated into an unlocking slot similar to that of a "J" tool

After the drive keys have entered the unlocking slot

as shown above, complete release is effected by simply continuing to raise the drill string. The upper part of the tool disengages from the lower part, thereby releasing the drill pipe from the stuck drill collars and bit to permit full recovery of the drill pipe. Only the above

actions,

performed in proper sequence, will disengage the Bumper Safety Joint

SHAFFER-WAGGENER BUMPER SAFETY JOINTS

(Patented)

PRECISE CONCENTRICITY ELIMINATES WOBBLE AND MISALIGNMENT

The Shaffer-Waggener Bumper Safety Joint is so designed that the two sections of the tool-the mandrel and the barrel-triple-lock in true alignment at three widely spaced points to provide maximum stabilization of the complete tool. As shown in Fig. 157 the upper point of stabilization is at "A" where (1) the taper of the mandrel and barrel centralizes the mandrel within the barrel-and (2) the helically-cut angle on the face of the taper causes the mandrel to rotate slightly with respect to the barrel, wedging the locking keys at "B" into tight engagement to prevent any rotational movement between barrel and mandrel. The close hardened-and-ground fit at "C" between the stabilizing shoulder on the mandrel and the sleeve of the barrel provides a third point of stabilization near the bottom of the tool to prevent any "rocking" action between barrel and mandrel. Since these three stabilizing points are spaced well apart, ample leverage is provided for holding the tool in precise alignment and rotational concentricity during high speed or rough drilling operations. To further assure close concentricity tolerance, each individual Shaffer-Waggener Bumper Safety Joint is carefully tested for concentricity before shipment. Tests are nade on specially designed equipment which parallels the conditions encountered in high speed, deep well drilling operations, and concentricity tolerance is held to closer .imits than those of other elements in the drill string.

OIL-SEALED JAR SAFETY JOINTS

(Patented)

This Jar Safety Joint combines a straight pull rotary jar with a safety joint ir one single tool. It replaces the two single-purpose tools-the jar and the safety joint-generally employed in fishing, testing and diamond coring, and reduces rig timE required to make up the string. It provides a powerful upward blow by mere!;; pulling on the string witlio1lt any rotation and a series of blows can be clelivere( as rapidly as the string can be raised and lowered. All operating mechanism is completely oil-sealed. No abrasive mud, sand or corro· sive chemicals can contact the operating mechanism-which gives uniform dependa· bility, minimum maintenance and maximum operating efficiency. In fighing operations, using the Oil-Sealed Jar Safety Joint, both jarring anc releasing actions are provided in one tool with consequent increased economy anc efficiency. Since this tool does not require the use of rotation or torque for jarring there is no clanger of interference with the operation of other equipment in the strin~ which might be affected by torque. In formation and casing testing, the Oil-Sealed Jar Safety Joint is run directl) above the packer and will deliver a powerful upward blow at the lJoint where i will be most effective. If the jarring should fail to dislodge the packer, the safet) joint feature may be utilized to bring the test sample out of the well without losint the results obtained by the testing operation. In diamond coring, the diamond bit and the core barrel substantially fill the hol1 and there is a strong tendency to stick the core barrel or bit when coming out. Th• cuttings, flowing through the small clearance, become especially dangerous whe1 circulation is stopped as the pipe starts out of the well. It is best to install th• Jar Safety Joint between the drill collars and the core barrel so that jarring actio1 of the tool will have the maximum effect.

In addition to replacing separate jars and safety joints, this combined tool i shorter than either one of these single-purpose tools usually employed. Unlike man~ types of jars, no special care is necessary when making it up in the string and clue to its ease of handling, it can be made up on the derrick floor or on the pip, rack with a saving in time up to one-half hour. High tensile strength alloy steels are used throughout and all parts are hea treated to assure maximum strength. Circulation can be maintained through th entire length of the Jar Safety Joint and two-direction chevron packing provide an effective seal against leakage from pressures encountered in either normal o reverse circulation. The Jar Safety Joint drives on three keys (C) and not thro1lgh threads. Th strength of the three keys is greater than the strength of the drill pipe on whic: the tool is run and thus allows full torque of any amount that may be exerte, in either direction. Wobble and misalignment which cause "working" and subsequent failure ar prevented by the stabilization features which can be seen in Fig. 159. The Spli Knocker Head on the Mandrel (A) maintains a close concentricity tolerance wit the Barrel and forms the upper point of stabilization. The close hardened-an( ground fit between the Mandrel and Barrel (below the Drive Keys) where the "0 Rings are located provides the lower point of stabilization. These two widely space points provide maximum stabilization at all times . WITH HYDRAULIC TRIP

Can also be furnished with a Hydraulic Trip Mechanism.

OPERATION AS A JAR Referring to Fig. 159, a straight pull on the string expands the Trip Spring ( 4 and releases it from the Trip Mandrel ( 5). The string of pipe, stretched by U straight pull, lifts the Barrel (2) upward with a sudden movement and causes U Split Knocker Head (B) on the inside of the Barrel to strike the Split Knoch Head (A) on the :Mandrel with a powerful blow, as indicated in Fig. 158. The amount of pull required to expand the Trip Spring is governed by the tensio in the Disc Spring ( G) which tends to keep the Trip Spring closed. This trippin action is particularly reliable because it does not depend on friction in any wa: When the string is lowered after the blow is struck, the Disc Spring will force tl Trip Spring clown until its top reaches the beveled shoulders in the Trip Mancln The Trip Spring then contracts and locks the tool ready for the next blow, whic can be delivered immediately. The jarring action is thus automatic with the raisir and lowering of the string on which it is run and any number of blows of equ, intensity can be struck. If blows of greater or less intensity are desired, the J; can be pulled out of the well and an adjustment made.

The force of the hlow is controlled by the tension in the Disc: Spring (6) and any blow frorn to 60 tons can be delivered by using the vroper Spa.cer (11) in the .Tal» The Shaffer Oil-Seal1 Safety Joint is pre-set before it is run into the well for the Llow desired. Tei adjust the force intensity of tl1e blow, it is only necessary to unscrew the Top Sub (1), withclra'v the Spacer (] abOYe the Disc Spring (6), and insert the Spacer that will exert the tension on the Disc SpriI that will giYe the blO\\,- desired. A set of Spacers which \Vill deliYer blows fron1 10 to 60 Lons 5-ton steps is proYided with the tool. After inserting the proper Spacer aboYe the Trip 81win the •rop Sub is screwed on again and the Jar Safety Joint will then trip at the new load.

OIL-SEALED JAR SAFETY JOINTS

(Patented)

OPERATION AS A SAFETY JOINT The Jar Safety Joint is released by first tripping the tool and thus placing the Barrel at the top of its stroke, as indicated in Fig. 160. Sufficient rotation to the left is then applied to the string at the surface to insure a torque on the tool. \Vhile this torque is being maintained, the string is slowly lowered. As the Barrel slides downward, the torque will cause the Drive Keys on the Barrel to move through unlocking slots or "escape windows" and into releasing passageways on the Mandrel as shown in Fig. 161. This action is similar to that of a "J" tool and requires a rotational movement of one-sixth turn at the tool. The string is then raised until the Safety Shear Pins in the Barrel contact the Split Knocker Head on the Mandrel. A strain is taken to shear these Pins and the upper part of the Jar Safety Joint is pulled out of the well.

EASILY RECONNECTED The Jar Safety Joint can easily be reconnected to the fish after releasing. Upon running back into the well with additional equipment, or after adjusting the intensity of the blow to be delivered by the Jar, the string is rotated slowly to the right while lowering the Barrel over the Mandrel. When the string starts to show resistance to rotation, it is lowered farther until the tool locks. (The engagement can be checked by the circulation of the fluid). After the Jar is locked, it is ready to perform its full functions as a Jar and as a safety joint. JAR SAFETY JOINT SPECIFICATIONS

SAFETY SHEAR PIN

Although the possibility of acciently manipulating the Shaffer >il-Sealed Jar Safety Joint into be releasing position is very re10te, three bronze Safety Shear 'ins (Part 10 in Fig. 159 and 1dicatecl by the arrovvhead in 'ig. 161) provide an added safety ieasure. These bronze Safety hear Pins also make it unnecesary to reset the tool after jarring Jose a stuck fish or a packer and 1e Jar Safety Joint can be withrawn from the well in the tripped osition with complete safety. The 'ins shear at approximately 20 ms in the sizes of Shaffer Oilealed Jar Safety Joints generlly used (for drill pipe of 3 1;!," nd 4 ~;,, ") and will thus carry up ) 20 tons out of the well. vVhen the tool is to be released, 1e Safety Shear Pins must, of mrse, be sheared and this will 3quire an upward strain of 20 ms on the string. The Barrel ncl tripping mechanism can then e pulled out, leaving only the [andrel in tbe well.

BUMPER SUB A Bumper Sub is a splined, telescoping slip joint which is capable of transmitting torque at every position of its stroke. It is run in a drilling string, usually at the top of the drill collars. A jarring blow, either up or down, can be delivered by a Bumper Sub. An upward blow is struck by: 1. Take a stretch in the pipe.

2. Measure the amount of stretch. 3. Release the brake and allow the block to fall a distance equal to the stretch pre.viously taken in the pipe. 4. Set the brake quickly. 5. The downward traveling string partly closes the Bumper Sub and spring action of the drill string snaps back to deliver an upward blow. A downward blow is struck by: 1. Elevate the string to make sure the Bumper Sub

is stroking and locates the top and bottom o the stroke. 8. The string is picked up to the middle of th< stroke and drilling is started. A longer stroke can be provided by running tw1 Bumper Subs together and treating the combinatio1 as though it were one Bumper Sub with twice th1 stroke length. A pump-open force exists in all unbalanced Bumpe Subs due to the pressure drop across the bit. A Bumpe Sub, unfortunately, is a simple piston and the pressur drop across the bit tries to pump it into the full. open position. Sufficient drill collars should be ru; above an unbalanced Bumper Sub to overcome thi pump-open effect. When stroking an unbalanced Bumper Sub (withou drill collars above it), the mud pumps must be shu down to eliminate the pump-open effect and obtai proper action of the Bumper Sub.

is fully open. 2. Release the brake and allow the block to fall a distance equal to the stroke of the Bumper Sub. 3. The downward traveling pipe closes the Bumper Sub quickly and delivers a downward blow. By using the above techniques, a Bumper Sub can be made to deliver a solid blow either upward or downward and repeated blows can be made in one direction or alternately in up and down directions. This allows the operator to instantly jar upward or downward to release drill collars, reamers or bits that may have become stuck or key seated in the hole. Floating drilling vessels use Bumper Subs to keep a constant weight on the bit regardless of the wave action on the drilling ship. 1. The drill string is run in the hole until it touches bottom. 2. Weight is slacked off until the Kelly moves downward a distance equal to the stroke of the Bumper Sub with no decrease on the weight indicator. This indicates that the Bumper Sub

A pressure balanced Bumper Sub, such as the Typ "D", will eliminate the pump-open effect because th built-in pressure chamber develops a closing fore which exactly balances the pump-open force. An oil-sealed spline section gives a much greater rm ning life. The oil seal prevents abrasive mud and san or corrosive chemicals from coming in contact wit the splines. The oil seal also provides optimum lubr cation to the splines which are transmitting a larg amount of horsepower. A complete line of Bumper Subs is offered to fill eve1 need as shown in the following table:

THE TYPE nB 11 REGULAR BUMPER SUB The Type B. Regular Bumper Sub (Fig. 163) is the simplest, most compact Bumper Sub available. It has one seal which retains the mud inside the drill string and a set of splines which are exposed to the return mud. A downward blow is delivered when the drive sleeve (Item 3) moves downward and strikes the shoulder of the mandrel (Item 2.). An upward blow is delivered when the drive sleeve (Item 3) moves upward and strikes the lock ring (Item 4) which is attached to the mandrel.

THE TYPE nBS0 11 OIL-SEALED PUMPER SUB ':H-©'; \.-!: '

The Type BSO Oil-Sealed Bumper Sub (Fig. 164) has an oil-sealed splined section which gives it an increased life. The oil is retained in the spline area by seals (Item 12) which are attached to the mandrel. The drive sleeve (Item 3) has a long skirt which rides over these seals. Since the OD of the bottom seal (Item 12) and the top seals (Item 6) is the same, the volume of the spline area does not change as the tool strokes. Therefore, oil can be inserted without the bumper sub becoming hydraulically locked. A downward blow is delivered when the drive sleeve skirt (Item 3) moves downward and strikes the shoulder of the mandrel (Item 2). An upward blow is delivered when the drive sleeve (Item 3) moves upward and strikes the lock ring (Item 4) which is attached to the mandrel.

BUMPER SUBS-TYPE nou PRESSURE BALANCED LONG STROKE The Type "D" Bumper Sub is a telescoping tool capable of transmitting torque at every position of its stroke. The design incorporates a pressure balancing feature that defeats elongation of the tool due to internal pressure. A built-in pressure chamber uses the circulation fluid itself to develop a closing force that exactly balances the "pump open" forces genernted in conventional bumper subs by circulation. The pressure balance feature makes this Type "D" Bumper Sub particularly useful in ope1·ations such as squeeze cementing, testing, and drilling with high circulation pressure or drilling top hole where the weight of the drilling string would not be heavy enough to offset a "pump-open" effect. Basically the Type "D" Bumper Sub is a slip-joint that is capable of transmitting torque at every position in its stroke, thereby enabling the operator to isolate the weight of the drill string from the drill collarR above the bit. ·

Other tool sizes and strokes are aYailable. Example: Type "D" Bumper Sub 6:xl, 0.D. x 2~ I.D.-60" stroke with 4llz A.PI Full Hole Toe Joint Connections pt. no. 671653.

section. Since the OD of the bottom and top seals is the same, the volume of the spline area does not change as the tool strokes. Therefore, oil can be inserted through the oil fill plug (item 14) and the tool will stroke without becoming hydraulically locked. The mud slots are the elongated slots in the upper barrel (item 13) as shown in figure 167 just below item 2. These slots are necessai-y to allow the return mud to flow in and out as the Yolume of the cavity above the mandrel changes when the tool strokes. The streamlined throug·h-bore facilitates passage of instruments and circulation of fluids through the tool.

DISC-LOK SAFETY JOINT

BEAUMONT, TEXAS Subsidiary of The Rucker Company

(Patented)

The Disc-Lok Safety Joint is a twosection releasing tool which provides a means of parting the drill string should the need arise. It features a unique belleville type disc spring lock which places a predetermined compression on the broad helical matching surfaces of the threads of the mating pin and box sections. It is impossible to back off the safety joint until sufficient weight has been applied to overcome the spring load. The Safety Joint is made up in the tension area of the drill string and is not affected by rotational torque, tensile loads or vibration. Specially designed helical matching threads of the pin and box sections assure quick and easy engagement. When the threads and reversely pitched shoulder surfaces are in full engagement, the two sections form a solid and integral unit. A secure pack-off is assured by the dual sealing elements.

FAST RELEASE

To release in the hole, the weight of the drill string is set down to overcome the locking friction and the string is rotated slowly to the left. Proper disengagement of the safety joint is indicated at the surface by the elevation of the drill string as the fast helical lead unscrews. The fast helical thread will result in quick release of the safety joint. Re-engagement is also very simple and very fast. Simply lower the string until the two sections make contact. Apply very little weight and rotate slightly to the left. Combined lowering and rotation to the right until torque increases assures full joint engagement. The Disc-Lok Safety Joint is available in all tool joint sizes for drilling, testing or fishing. It is also available as a Tubing Safety Joint or Wash over Safety Joint.

THREADLESS QUICK DISCONNECT TOOL JOINT This Tool Joint is released by use of a simple lever which engages the releasing mechanism through a small vertical slot in the joint housing. There are just two basic parts-the mandrel and the barrel assembly. Three keys machined into the inner surface of the barrel mate with three helically cut slots in the body of the mandrel. These keys foll ow the slots until the barrel is as far down over the mandrel as it can go. At this point locking lugs on the key sleeve within the body of the barrel become aligned with a set of vertical grooves in the mandrel, allowing the key sleeve to drop into locking position where it holds the barrel keys in place. The spring force keeps the key sleeve pressed into the locking position and prevents the barrel keys from rotating out of the helical slots in the mandrel. QUICK CONNECTION

Making a connection is a simple stabbing operation. As soon as the barrel is lowered over the mandrel, it makes a quick onethird turn and the connection is made! It is not necessary to rotate the barrel as it

(Patented)

Fig. 168 Disc-Lok Safety Joint

is lowered over the mandrel because the steep slope of the helix is sufficient to cause the barrel to move into proper position. The two parts cannot be over-tightened or jammed and will not separate by either right or left hand torque, compression or tension. Complete pack-off is assured by the dual seals on the end of the mandrel. Although the mandrel and barrel lock together as an integral unit, the two parts can be separated easily by a special disconnect tool. A vertical slot in the barrel provides access to the key sleeve so the locking lugs may be lifted out of the spring. The disconnect tool is inserted into the vertical slot of the barrel where it engages the locking sleeve. Lifting the disconnect tool (manually in small sizes and with the assistance of a tugger line in the large sizes) will relase the joint. The release is fast and requires little or no experience. Threadless Quick Disconnect Tool Joints are made in all sizes and for many applications. They can be furnished with flash weld connections or they can be furnished in the form of a sub to screw onto existing drill pipe.
