A New Model for a Fractured Well in a Radial, Composite Reservoir

Abstract

Summary A flow problem was identified by using a pressure-derivative technique to analyze several hundred pressure-falloff tests from the Big Hom basin. To handle the problem, a new analytic model was developed to allow direct analysis of fractured wells with either finite conductivity or uniform flux in a radial, composite reservoir. In this paper, we demonstrate that this simple model further explains the buildup-pressure behavior of a fractured well producing below dewpoint pressure in a gas-condensate reservoir.
