Geothermal reservoirs in the Upper Rhine Graben (URG), faults and fractured rock masses

Hecht, Christian A.

Abstract

Fractured rock masses have the highest potential to provide the essentials of geothermal reservoirs for power production like high permeability, high flow rate, large heat exanger rapid heat transfer and others. They playa key role in the development of geothermal power projects in the Upper Rhine Graben (URG) and elsewhere. Compared to hydrocarbon reservoirs fairly little is known about geothermal reservoirs in this area. The following paper gives an overview about the status qou of geothermal development in the URG with special emphasis on faulted and fracturedreservoirs.
