This paper presents a new technique for predicting performance of an abnormally pressured gas reservoir. The method maintains the straight line relationship for conventional P/Z's (p-reservoir pressure, psia; z- compressibility factor) in normally pressured reservoirs and allows direct extrapolation of original gas in place in abnormally pressured reservoirs by accounting for rock and water compressibility in the adjustment factor term. This method has been successfully applied to three abnormally pressured reservoirs. They are the North Ossun Field in Louisiana, the Anderson 'L' gas reservoir in South Texas, and a Louisiana offshore gas reservoir. The results of the application of the new method and a comparison of predicted performance in abnormally pressured reservoirs using this technique and the conventional P/Z method are presented. 7 refs.
