dc.description.abstract Productivity index (PI ) is an important indicator of a well ?s production capacity . For conventional reservoirs , well productivity is usually calculated using the pressure response of the reservoir in its pseudosteady -state period . There are numerous studies for different well completion schemes which developed correlations for pseudosteady -state productivity index for specific cases , such as horizontal wells and fractured wells . Most of the developed models for complex well completion schemes use some approximations for productivity index calculation and they have some limitations in use . Furthermore , as the petroleum industry goes toward producing lower quality reservoirs like low - and ultra low -permeability reservoirs , the period of transient flow covers a larger part of the well lifetime and these pseudosteady -state productivity calculations become less applicable in prediction of the reservoir ?s production behavior . The Distributed Volumetric Sources (DVS ) method seems able to fill this gap . Our method is able to predict the productivity index of a general well completion scheme for transient as well as pseudosteady -state flow periods . In this study , we focus on a typical well completion scheme ? vertical well intersected by a vertical fracture of finite conductivity . Parametric study is performed by varying the proppant pack permeability with a linear distribution , varying fracture width with an elliptical distribution and varying fracture height with an elliptical distribution . The details of hydraulic fracture are integrated into the calculation of well productivity . By combining the well productivity with gas material balance , production forecasting of the hydraulically fractured wells could be easily obtained . The result of production forecasting could be used to aid in decision making of choosing the best stimulation treatment . Field examples are presented to illustrate the application of this technology for production modeling the complicated reservoir cases involving fracture stimulation . en_US
