COUPLED THERMAL-HYDROLOGICAL-MECHANICAL-CHEMICAL PROCESSES IN GEOTHERMAL AND SHALE ENERGY DEVELOPMENT
The growing world population necessitates development of a wide range of energy resources. Enhanced Geothermal Systems (EGS), a type of deep geothermal energy, is a clean and renewable source of energy. Despite its significant potential, EGS development has not gained enough attention in part due to existing practical limitations and knowledge gaps. In addition, despite the desire to fully transition away from fossil fuels toward renewable energy resources, the existing gaps can be filled with cleaner sources of fossil fuel such as natural gas. Shale gas, one of the unconventional resources of natural gas, can be used to fill the existing gap as we move toward renewable energy-based infrastructure. In general, coupled Thermal-Hydrological-Mechanical-Chemical (THMC) processes that exist in both shale gas and EGS reservoirs development affect the fracture response (i.e. aperture and permeability), which in turn influences the reservoir production. Therefore, it is critical to investigate the effects of THMC processes on the response of fractured reservoirs to better: (i) design stimulation (i.e. hydraulic fracturing or hydro-shearing) program, (ii) understand the response of the fractured reservoirs, and (iii) optimize the reservoir production.
