GEOTHERMAL ENERGY: ENHANCED GEOTHERMAL SYSTEMS
The Enhanced Geothermal Systems (EGS) concept is to extract heat by creating a subsurface fracture system to which water can be added through injection wells. Injected water is heated by contact with the hot rock and returns to the surface through production wells. EGS are reservoirs created to improve the economics of resources without adequate water and/or permeability. EGS may be feasible anywhere in the world, depending on the economic limits of drill depth.
