We deployed 3C receivers along several 2D lines during a 3D survey that covered the southern part of the city of Munich in the Bavarian Molasse Basin, targeting the carbonate platform at depths of 2 – 3 km. Although restricted to a limited number of receivers, we succeeded in deriving shear-wave velocities for both the Molasse sediments as well as the carbonate reservoir. We used interval travel times to determine the vp/vs relation, which is, complementary to the velocities themselves, a valuable lithological indicator that we use to discriminate limestone and dolomite facies. Although the proof of this prognosis by drilling is still to be carried out, it is strongly supported by the comparison with an independently-derived seismic facies classification.
