Because of the low-permeability nature, stimulated reservoir zone (SRZ) must be created in order to effectively extract gas from shale gas reservoirs. When the gas is extracted, a multiple of physical processes is triggered in SRZ, non-SRZ and hydraulic fractures, and all of them are stress-sensitive. Although these stress-dependencies were investigated in previous studies, the complexity of interactions between different domains (SRZ, non-SRZ and hydraulic fractures) and among multiple physics in each domain has not been understood well. In this study, a fully coupled, multi-domain and multi-physics model is developed to thoroughly capture this complexity. Shale reservoir is characterized as an assembly of three distinctive components: kerogen (in both SRZ and non-SRZ), inorganic matrix (in both SRZ and non-SRZ) and hydraulic fractures. Furthermore, kerogen and inorganic matrix are defined as …
