The total cumulative gas production is the difference between original gas in place and gas in place at some().
Because of reservoir(), the encroaching water does not sweep some portions of the reservoir effectively.
To account for the unswept portions of the reservoir, we introduce a() into the volumetric equation.
Material balance methods provide a simple and effective methods for estimating() at any stage of reservoir depletion.
