The objective is to address the impacts of scale-dependent heterogeneities on gas production. The heterogeneities are characterized at three levels: (1) heterogeneous structure of the matrix; (2) discrete structure of the NFNs (Natural Fracture Networks); and (3) discrete structure of the HFs (Hydraulic Fractures). This has led to a series of multiphysics models for gas extraction from unconventional gas reservoirs. All models are verified against either analytical or field data. All results confirm that heterogeneities at all scales are important, but their respective roles evolve separately during the histories of unconventional gas production.
