Summary:
The German Molasse Basin is part of the greater Northern Alpine Foreland basin and has been extensively explored and exploited by the hydrocarbon industry in the 1950s-1970s. Today, the Molasse Basin area is a main target for deep hydrothermal energy exploration and production in Germany. Although the sediments of the Molasse Basin are increasingly overpressured towards the Alps and despite continuous drilling events in the overpressured parts of the Molasse Basin, an analytical, predictive model that can be used for predrill pore pressure prediction based on offset well data and local geology is not existent, yet. Instead, the current understanding is mainly based on the regional distribution of maximum drilling mud weights and offset drilling events and postulates a combination of high sedimentation rates and Alpine tectonic stress. In this study, we aim to systematically investigate the compaction behavior of the overpressured shales throughout the basin as well as the contribution of tectonic stress, local lateral pressure transfer and other effects on overpressure generation. The ultimate goal is to develop a reliable pore pressure prediction model for future well planning in the German Molasse Basin. We would like to introduce the project and show examples and first results.
