Although a number of researches for modeling of shale gas reservoirs have been conducted, there is a definite lack of literature that concentrates on the geomechanical effects. To account for geomechanical effects with stress dependent porosity and permeability, linear elastic geomechanical model and two stress dependent correlations were applied to the reservoir model. Through coupling of flow and geomechanical models for well/reservoir/hydraulic fracture combinations, new approach has been established to predict the pressure transient behavior and to generate type curves. Geomechanical mechanisms influence production from 1 to 5 % in shale gas reservoir. This study provides insight into the characteristics of a hydraulically fractured horizontal well and the newly developed type curves yield more unique and accurate results.
