Reservoir Characterization of the Coal-Bearing Upper Carboniferous Clastic Succession, Ruhr area, Germany

Greve, Jonas; Busch, Benjamin; Quandt, Dennis; Hilgers, Christoph

Abstract (englisch):
With the successive closure of coal mining in the northwestern German coalfields including associated cessation of active mine water drainage, heterogeneous ground movements are related to the rising mine water table. The Ruhr district is one of the world’s best documented subsurface 3D rocks volume. It thus offers to better understand the change of reservoir properties at varying effective stresses in a reservoir-scale. In the scope of the interdisciplinary FloodRisk project, reservoir properties of Upper Carboniferous (Westphalian A and B) drill cores are investigated for selected German mining areas in the eastern Ruhr area as their characterization is crucial to process understanding. The cyclic succession of the clastic Westphalian units was deposited under fluvio-deltaic (paralic) conditions in the late Carboniferous Ruhr Basin. In the Westphalian, the interplay of rapid basin subsidence, sedimentation rate, and glacio-eustatic sea-level changes controlled the sedimentation pattern and promoted paralic coal-forming environments. Drilled cores from three exploration wells in the study area stratigraphically cover the Witten, Bochum, and Essen Formation of the Westphalian A and B. ... mehr
