 Analogy-Based Approach Estimate the reserves in a situation where there are no solid data on well performance or reservoir characteristics. However, an analogue-based approach is also the least accurate and little reliable method of petroleum reserve estimation,

Volumetric Estimates Deterministic Methods: The principle is to "upscale" the information derived from the wells and supported by seismic survey, into the interwell space by using an interpolation technique.

Institute of Petroleum Engineering

Volumetric Estimates (Deterministic Method)  The main parameters used for a volumetric estimate:  The reservoir "gross" isopach map,  The reservoir "net" isopach map, The Net-to-Gross ratio (N/G) is an important parameter indicating the productive portion of the reservoir.

 The reservoir rock porosity  The permeability and net-thickness product (khN)  Volume-based average saturation of water, gas and oil.

Institute of Petroleum Engineering

Volumetric Estimates (Stochastic Method) is usually based on the procedure of random-number generator Assumes that the main reservoir properties all have random, possibly normal, frequency distributions, range from core to well-log data.

Volumetric Estimates (Stochastic Method)

Institute of Petroleum Engineering

Performance Analysis Material Balance Equation is based on the data obtained from previous reservoir performance and PVT analysis, but involves some assumptions for the reservoir driving mechanism.

Reservoir Simulation Models involves a numerical simulation technique, with the matching of the production and the reservoir’s previous performance (history).

Decline Curve Analysis is to predict future performance of the reservoir by matching the observed trend of the production decline with one or several standard mathematical methods of the production rate-time (hyperbolic, harmonic, exponential, ect.).
