N2 - The Bavarian Foreland Molasse Basin (BFMB) in SE German is the most prolific geothermal play in Germany and displays variable lithological, geomechanical and temperature distributions, which impact deep geothermal exploration and are likely related to the regional permeability distribution of seal rocks. The thermal water is produced from Upper Jurassic Carbonates from depths between 500-5000 m below ground level and at temperatures between 30-150°C. In addition, the BFMB provides units which are utilized for gas storage, and parts of the BFMB have also been identified as possible sites for nuclear waste storage. In order to better understand sealing capacities and in particular thermo-hydraulic processes in the BFMB, more than 500 wells have been screened and a regionally representative subset with high data quality have been analyzed to better understand vertical effective stress and sediment compaction variations on a regional scale. The results will be used to calibrate a 3D basin model of the BFMB to obtain regional insights on the permeability distribution and thermo-hydraulic dynamics in the BFMB. In this contribution we will present the overall workflow and first results from regional compaction and vertical effective stress analyses.
