Risk mitigation for geothermal projects using 3D-seismics
The commercial use of hydrogeothermal energy largely depends on the exploration risk. Deep drillings require financial investments of several million €, without ensuring the necessary flow rates and temperatures. A risk mitigation can be achieved by the use of seismic methods, which have been developed by the oil and gas industry. Methods like 3D seismics and analysis of seismic attributes are by now standard methods used by the industry. Within the framework of this project we want to investigate the adoption of these techniques to data acquisition, processing and interpretation with respect to geothermal projects. Existing 3D datasets from the oil and gas industry will be analysed and compared with corresponding results of 2D seismic data. The datasets cover three regions in Germany that are relevant for hydrogeothermal use (Molasse Basin in southern Germany, Upper Rhine Graben and North German Basin). Supplementary high resolution near surface seismics will be used to image fault systems.
