This study investigates the stress-strain effects on gas production from shale formations, a crucial component in understanding the efficiency of gas extraction in unconventional reservoirs. Shale gas production relies heavily on hydraulic fracturing, which alters the stress-strain relationship within the formation. This paper presents a comprehensive analysis of how mechanical stress influences gas permeability, production rates, and the overall sustainability of shale gas operations. By examining field data, laboratory results, and numerical simulations, we evaluate the impact of stress changes on fracture propagation and gas flow in shale formations. The results indicate that the stress-strain behavior significantly affects gas recovery, with implications for optimizing drilling and fracturing processes. This research provides insights into the critical factors that control the performance of shale gas reservoirs and offers practical recommendations for improving production efficiency.
