Simple Calculation of OGIP and Water Influx in Gas Pool by Water Drive Process

Abstract

Abstract: Original gas in-place (OGIP) and water influx in gas pool by water drive process are the key parameters for determination of a gas pool development scale and production plan. Using apparent geologic reserves method, only production performance data are needed without water influx, the OGIP can be estimated from mapping apparent geologic reserve curves, and then the water influx can be backward calculated by putting the OGIP data into the equation for apparent geologic reserves. The case study and correlation indicate that the results given by this method are accurate and reliable.

Key words: water drive, gas pool, gas reserve, water influx, calculation, estimation
