Quantitative Comparison of Three Shale Gas Extraction Schemes via Coupled Hydromechanical Simulation
This study employs COMSOL Multiphysics to build a hydromechanical (HM) coupling model for shale gas production based on classic poroelasticity and Darcy’s law. Considering effective stress variation during depletion, a stress-dependent permeability model is incorporated into the dual-porosity framework. Numerical simul...
