Pressure-dependent Production Efficiency of an Enhanced Geothermal System (EGS): Stimulation Resultf Germany. The intended purpose of these experiments was to develop concepts for a productivity increase of the geothermal well to create an Enhanced Geothermal System (EGS). Two different kinds of stimulation types were performed. Hydraulic gel-proppant stimulations were conducted in sandstone sect
