A dry gas material balance with an infinite aquifer influence: A comparative study between the unsteady state model of van Everdingen-Hurst and analytical model
Aquifer water influx is an important natural mechanism for primary recovery. It affects the performance of all types of reservoirs, also natural gas reservoirs. Water influx provides pressure support during reservoir depletion, resulting in slower pressure decline. Consequently, gas reservoirs associated with large aquifers show a flattening, cubic behavior of the p/z vs. Gp curve, which allowed the development of the...
