Stress-Induced Symmetry Breaking and Well-Specific Hydraulic-Fracturing Design in Deep Shale Gas Reservoirs: Field-Calibrated Numerical Analysis and Engineering Evaluation
Deep shale gas reservoirs are subjected to anisotropic in situ stresses that break the directional symmetry of hydraulic-fracture growth, promote propagation along the maximum horizontal principal stress, and suppress transverse spreading. This study investigates geomechanical and injection controls on fracture-network...
