This study deals with projecting production decline curves. It examines a generalized relationship of cumulative production versus time presented in the literature by Gentry1 . A production rate versus time relationship is derived from this general equation. Four methods of determining the constants appearing in both equations is presented. The equations are used to model solution-gas drive production (simulated and actual field case studies). The goal is to determine the uti1ity of using the equations to evaluate solution-gas drive reservoirs.
