3D seismic survey explores geothermal targets for reservoir characterization at Unterhaching, Munich, Germany

A 3D seismic survey was undertaken as part of a research project to characterize the Upper Jurassic (Maim) hydrothermal reservoir at the geothermal power plant at Unterhaching, Munich, and to simulate its potential for sustainable usage. A suite of promising geothermal targets could be identified on this relatively small survey size of 27 km(2), where several geothermal projects are expected to. potentially influence each other. Among these targets are fault patterns of high complexity with en-echelon elements, circular structures, dolomitized reefs and mounds, reduced seismic velocities which indicate brittle disaggregation, and preferential orientations of joints and fissures.
