Relations between seismic signals and reservoir properties of deep gas reservoirs in Northwest-Germany - Wustrow member, Rotliegend Dissertation Zur Erlangung des akademischen Grades doctor rerum naturalium (Dr. rer. nat.) Vorgelegt dem Rat der Chemisch-Geowissenschaftlichen Fakultät der Friedrich-Schiller-Universität Jena Von Dipl.-Ing. Peter Abram Geboren am 28.

April 2007 Abstract This study tries to find the petrophysical basis for correlations between reservoir properties and seismic signals calibrated with geological information for Wustrow-sediments of the Rotliegend in NW-Germany. A secondary objective consists in explaining the large scatter of permeability for Wustrow reservoir rocks of comparable properties. The correlations were ascertained in the DGMK-project 593-8, for instance to authigenic clay mineral types and permeability. The investigations demonstrate that the differences in seismic signals (amplitude, shape and lateral coherency of seismic traces) are a product of distinct compressional field velocities (from wireline logs) and attenuation processes as in-situ bulk densities are barely varying within the investigated horizon.
