Abstract: Combined Usher model with water drive curves , this paper presents a new simultaneous solution model for predicting water cut,oil production rate, water production rate, fluid production rate and cumulative oil production variations with development time and recoverable reserves of a water drive oilfield. This model solves the problems without water cut parameter in yield prediction model and without time factor t in water drive curves. Case study shows that the prediction accuracy by this model is relatively higher than others and the model can satisfy the requirements of performance prediction of development indices in water drive oilfields
