oa 3D Seismic Survey in Crystalline Rocks of Saxony, Germany

3D seismic measurements have been performed in 2012 to explore a petrothermal reservoir in a crystalline environment (granite intrusion, metamorphic cover) within the Erzgebirge in Saxony. The intention and challenge is to image and characterize a steeply dipping fault zone with potentially permeable fracture zones at target depths of 5-6 km and temperatures well above 150 °C. The vibroseis technique was used in the experiment. A suite of imaging methods has been applied, from conventional CMP-stacking, CRS processing to pre-stack migrations.
