THE EMPIRICAL METHOD FOR PREDICTING DEVELOPMENT INDEX OF OILFIELD

Abstract

Abstract: The combination of production decline curve with water displacement curve gave a complete set of empirical method for predicting development index of oilfield, which avoided the neglect of watercut in production decline curve prediction and the neglect of time in water displacement curve prediction. It can also be used to predict the remaining development life of oilfield and oil recovery rate when it is abandoned.Case study showed that high watercut stage is an important period of oilfield development. It is suggested that we should take quite more care of the estimation of recoverable reserves with production decline curve because it is always overestimated.

Key words: Oil and gas field, Production, Decline, Water drive, Development index, Prediction, Ultimate recoverable reserve, Ultimate recovery
