Pseudo-steady state (PSS) flow is an important time-dependent flow regime that<br/><br/>quickly follows the initial transient flow regime in the constant-rate production of<br/><br/>a closed boundary hydrocarbon reservoir. The characterization of the PSS flow<br/><br/>regime is of importance in describing the reservoir pressure distribution as well as the<br/><br/>productivity index (PI) of the flow regime. The PI describes the production potential<br/><br/>of the well and is often used in fracture optimization and production-rate decline<br/><br/>analysis. In 2016, Chen determined the exact analytical solution for PSS flow of a<br/><br/>fully penetrated vertically fractured well with finite fracture conductivity for reservoirs<br/><br/>of elliptical shape. The present work aimed to expand Chen’s exact analytical solution<br/><br/>to commonly encountered reservoirs geometries including rectangular, rhomboid,<br/><br/>and triangular by introducing respective shape factors generated from extensive<br/><br/>computational modeling studies based on an identical drainage area assumption. The<br/><br/>aforementioned shape factors were generated and characterized as functions for use<br/><br/>in spreadsheet calculations as well as graphical format for simplistic in-field look-up<br/><br/>use. Demonstrative use of the shape factors for over 20 additional simulations showed<br/><br/>high fidelity of the shape factor to accurately predict (mean average percentage error<br/><br/>remained under 1.5 %) the true PSS constant by modulating Chen’s solution for<br/><br/>elliptical reservoirs. The methodology of the shape factor generation lays the ground<br/><br/>work for more extensive and specific shape factors to be generated for cases such as<br/><br/>non-concentric wells and other geometries not studied.
