The geothermal research well GtGrSk4/05 at Groß Schönebeck, Germany, was hydraulically stimulated to develop an Enhanced Geothermal System in the Upper Rotliegend sandstones. Gel-proppant stimulation was selected to enhance reservoir productivity and to maintain it over the long-term. Before the field tests, laboratory experiments were carried out to study embedding effects and long-term hydraulic conductivity changes in intermediate-and highstrength proppant types. Based on the laboratory results it was decided to place in the stimulated fractures large concentrations of a high-strength proppant. The success of the stimulation of GtGrSk4/05 was confirmed by production test and flowmeter log data.
