Title: A simple method for predicting recoverable reserves of reservoir
Abstract: This paper proposes a new differential equation for production declining rate,which has different form from differential equation of J.J.Alpes,and derives a method for predicting recoverable reserves of reservoir.The substance of this method is that,when oil and gas production starts declining,square root of annual oil production and accumulated oil production is a declining straight line in rectangular coordinate.Using this straight line and abandoned annual oil production can predict remained recoverable reserves of reservoir.Adding predicted value to accumulated oil production in declining period can obtain recoverable reserves of oilfield.This simple method can be used as an effective method to calibrate recoverable reserves of reservoir.This paper gives several cases to prove the reliability and feasibility of this method.
