A straight-line DCA for a gas reservoir

In decline curve analysis (DCA), the decline exponent (b) characterizes the variation of decline rate (D) with production, and significantly affects the long-term shape of the production profile. In most currently-available DCA methods, the decline exponent is assumed to be constant during the whole...

Zusammenfassung:In decline curve analysis (DCA), the decline exponent (b) characterizes the variation of decline rate (D) with production, and significantly affects the long-term shape of the production profile. In most currently-available DCA methods, the decline exponent is assumed to be constant during the whole production period. However, production decline of a gas reservoir does not follow exponential (b = 0), hyperbolic (0 < b
