Excavation based enhanced geothermal system (EGS-E): introduction to a new concept
Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2019 The current technology for enhanced geothermal system (EGS) typically involves drilling of deep injection and production wells to inject cold water into the injection well to the EGS reservoir depth, to extract heat by permeating through the fractured hot rock masses, collected by the production well and return to the surface as heated water.
