Abstract

Abstract: A new type cquation of decline curve is derived in this paper, based on the application of Arps's hyperbolic decline. Also, the modified Kopatov' s empirical formula, which has been widely used in at home, is derived and suggest that it is a specific case of Arps's hyperbolic decline when the decline exponent n is 1/2. The new type equationis a straight line equation and its solution can be easily given without using the trial and error method and curve shifting method.

Key words: Oil—gas field, Production decline, Recoverable reserve
