Comparative Analysis of Power Plant Options for Enhanced Geothermal Systems (EGS) [PDF]
Energies, 2014 Enhanced geothermal systems (EGS) extract heat from underground hot dry rock (HDR) by first fracturing the HDR and then circulating a geofluid (typically water) into it and bringing the heated geofluid to a power plant to generate electricity. This study

Fracture Transmissivity in Prospective Host Rocks for Enhanced Geothermal Systems (EGS) [PDF]
Geosciences, 2022 We experimentally determined the hydraulic properties of fractures within various rock types, focusing on a variety of Variscan rocks. Flow-through experiments were performed on slate, graywacke, quartzite, granite, natural fault gouge, and claystone ...

Hydraulic stimulation strategies in enhanced geothermal systems (EGS): a review
Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2022 AbstractIn enhanced geothermal systems (EGS), the natural permeability of deep rocks is normally not high enough and needs to be increased. Permeability increase can be achieved through various stimulation methods, such as hydraulic, chemical, and thermal stimulation.
