Hydraulic fracture modeling of an enhanced geothermal system (EGS) experiment
Enhanced geothermal systems (EGS) are analogous to the unconventional reservoirs of the oil and gas industry in size and extent. EGS reservoirs lack the presence of a reservoir fluid and a naturally permeable rock. The total energy reserves that can be classified as EGS are larger and more numerous compared to conventional geothermal systems. Unfortunately, they cannot be produced by conventional means. In order to capitalize on EGS, one must artificially induce a permeable network within these mostly igneous/crystalline rocks. The fractures allow the fluid, while being circulated from an injection ...
