Abstract: The generalized Weng's model, dual logarithm production decline curve model and water drive curve model are popular to use in reservoir engineering study. However, they have their own limitations. Integrated with these methods, this paper presented a combination prediction method to correct predictive results as well as providing explanation in, detail of their solutions. This method is not only. applied. to predict production, water production, the, top annual yield and related time in a hydrocarbon field by waterdrive process, but also to predict recoverable reserves, water cut and volumetric sweep efficiency. The result shows that it has much higher predictive power and precision compared with other models.
