The optimal reservoir configuration for maximum productivity index of gas reservoirs depleted by horizontal wells under Darcy and non-Darcy flow conditions

摘要

A new approach for estimating productivity index of horizontal wells depleting finite gas reservoirs is introduced in this paper. This approach focuses on using reservoir configurations and anisotropy as well as wellbore length for calculating productivity index at pseudo-steady state conditions when production time is no longer affects reservoir performance. The paper also aims to determine the optimal reservoir configurations that could give the maximum productivity index.
