Structural Architecture and Permeability Patterns of Crystalline Reservoir Rocks in the Northern Upper Rhine Graben: Insights from Surface Analogues of the Odenwald

Fracture network is a crucial element to address in any model of the thermo-hydro-mechanical behaviour reservoir rock. This study aims provide quantified datasets and further understanding critical parameters fracture pattern crystalline rocks. In Northern Upper Rhine Graben, such rock units are targeted for multiple energy applications, from deep geothermal heat extraction storage. Eleven outcrops were investigated with combined LiDAR 2D profiles analysis extract faults geometrical parameters, including length distribution, orientation, connectivity, topology. These properties used decipher structural architecture estimate flow units. networks show multi-scale power-law distribution. topology orientation mainly driven by both fault lithology. apertures permeability tensors then calculated two application case studies, stress field effect on aperture. Obtained permeabilities range those observed sub-surface currently exploited reservoirs. The dataset provided this thus suitable be implemented modelling during exploration stage industrial applications involving fractured
