Fundamentals of Fluids & Pressure

Pressure is defined as Force per unit area exerted by fluid i.e.

Pressure

Force

Area

Basic laws of physics concerning fluids & gas •

Liquids are not compressible

•

Gases are compressible

•

Liquids & gases are both FLUIDS

•

Pressure in a fluid is transmitted equally in all directions.

Fresh Water

Fresh water weighs the same per unit volume anywhere in the world that is why it’s called “Universal Fluid”& used as STANDARD for comparison with other

fluid. Fresh Water Facts: PG

= Force (Density/ft3) ÷ Area (ins2)

•

Density of 62.4

• • • • •

Density of 8.33 lbs/gal = 62.4 lb/ft3 ÷ 144 ins2 = 0.433 psi/ft 3 Density of 7.48 US gal/ft Relationship between Density (ppg) & PG PG of 0.433 psi/ft (psi/ft) is always the same  0.052 is used as SG of 1 constant for any calculation between them. API 10º

lbs/ft3

= 7.48 gal/ft3 ÷ 144 ins2 = 0.052 psi/ft

Formula of Density (ppg) = Density (lb/ft3)  Density (US gal/ft3)  Density (ppg) = 62.4 ÷ 7.48 = 8.33 ppg Formula of fresh water PG if density in ppg is given, PG = Density (ppg) × Constant Basic Wireline Operations / M.F.Radwan

= 8.33 ppg × 0.052 (constant) = 0.433 psi/ft 8

PRESSURE BASIC & BASIS 4

Specific Gravity (SG)

The ratio of the density of a substance compared to density of another substance which is used as the standard (Fresh Water). Many fluids in petroleum industry is expressed in SG as well as in wt ppg. It’s necessary to convert SG to PG to find HP.

To find SG of fluid simply divide fluid wt by fresh water wt. E.g. Salt water wt is 10 ppg.  Salt water SG = 10 ppg ÷ 8.33 ppg =

1.2

To find PG of fluid simply multiply fresh water PG by fluid SG E.g.

Find the HP of brine at 5000 ft TVD with brine SG of 1.17. HP of brine = 1.17 × 0.433 psi/ft × 5000 ft

PRESSURE BASIC & BASIS 5

API Gravity

API gravity is another value used to express relative wt of fluids & was introduced by American Petroleum Institute to standardized the wt of fluids at base temperature of 60º F. Water as standard fluid had been assigned the value of 10º API gravity. To convert API gravity to SG, the following formula is used. SG = 141.5 ÷ (131.5 + APIº) E.g.

Find the SG of 30º API oil SG = 141.5 ÷ (131.5 + 30º) = 141.5 ÷ 161.5 = 0.875

PRESSURE BASIC & BASIS 6

Hydrostatic Pressure (HP)

HP is the pressure developed by column of fluid at given TVD. “Hydro” means fluid & “static” means stationary.  HP is pressure created by stationary column of fluid. To calculate HP in psi of any fluid simply multiply TVD in ft by PG of fluid.

E.g.

Find HP in psi of fresh water at 500 ft TVD. HP = 500 ft × 0.433 psi/ft = 216.5 psi

To calculate HP in kPa of any fluid simply multiply TVD in meter by SG by 9.81 E.g.

Find HP in kPa of brine with SG of 1.32 at 1800 m TVD. HP = 1800 m × 1.32 × 9.81 = 23 308.56 kPa Bar = 23 308.56 kPa ÷ 100 = 233 Bar

To find BHA of 2 fluid column or more simply add the HP of the fluid column of the same unit of measurement together. Basic Wireline Operations / M.F.Radwan

What is Slickline  Small diameter wire with sufficient strength to accomplish the operation without breaking – why small?  Minimize the load of its own weight  Minimizing the cross-sectional area reduces the effect of wellhead pressure  Enables the use of smaller diameter spools, reels and sheaves without overstressing the material when bending

What is Slickline When selecting Slickline, several factors should be considered  Minimum breaking stress  Resistance to corrosion

 Effects of bending  Environmental conditions, desert dust, seawater, temperature  Well Pressure  Effecting the magnitude of force on the line diameter  Influencing the effects of H2S

Types of Slickline  Most popular material I.P.S. (Improved Plow Steel)  High ultimate tensile strength, good ductility, low cost  Minimum Breaking strain 0.125” – 2840lbs  Not suitable for H2S and CO2 conditions  Must be protected when not in use – line wiper used when removing from well, protective coating when stored on drum  Use of inhibitor subs and protective inhibitors

Basic Wireline Operations / M.F.Radwan

65

Types of Slickline  For wells with high H2S and CO2  Alloy and Stainless Steel lines  Materials not as strong as IPS (alloy 0.125” – 2220lbs)  Excellent resistance to corrosion  Line wiper still used when pulling out of the well, less need form immediate protection when not in used  Cost…..IPS x 12+

Pressure Testing • •

Max CITHP + Safety Factor (500 psi) & apply in stages. PT medium; 60:40 ratio by volume of fresh water & glycol respectively. (This would prevents “Emulsion” formation in oil wells or “Hydrates” if it would be discharged into wells)

De-Pressurize • • • •

Bleed off through production process venting system. If not possible, bleed off with extreme care, no personnel & source of ignition down wind. De-pressurizing must be a Controlled Operation. PATIENCE is the virtue of this case & NO ACCELERATION is permitted. Ensure that equipment is earthed to prevent ignition by static electricity.
