Abstract

Summary

The Upper Jurassic carbonate platform is the most utilized geothermal reservoir in Germany. To exploit its full potential, a large 3D seismic survey was conducted in the city of Munich. We used 3C MEMS sensors along several 2D lines to (1) record the shots of the regular survey and (2) to test a direct excitation of S-waves using the SHOVER technique. The Z-component of the single sensor MEMS recordings gave a comparable quality of the stack as a geophone group recording, although the noise level of single shot gathers was raised slightly. The passive recording of the 3D-survey shots gave clear converted wave signals as well from the top and from the inside of the platform. The application of the SHOVER technique was affected by practical issues in this urban environment, only single shots could be analyzed. They show reflections from the top of the carbonate platform on the radial and transversal components, however the suppression of P-waves turned out to be imperfect.
