The effect of aquifer size on the performance of partial water-drive gas reservoirs
Predicting the advance of a gas-water contact in a water drive-gas reservoir plays an important role in the evaluation, forecasting, and analyzing the reservoir performance. This study was conducted to predict the behavior and the rise of the gas-water contact assuming it remains horizontal, and to determine its effect on ultimate gas recovery. Several factors are recognized to control the rise of the gas-water contact. Some of the more important factors are the size of the aquifer, gas production rate, initial reservoir pressure, and formation permeability. Interaction of these factors account for the abandonment of a number of gas reservoirs at extraordinarily high reservoir pressures. Several methods have been developed for predicting the volume of water influx into a reservoir, the Van-Everdingen-Hurst method is used in this study.
