3D Stress Field Modeling for the German North Sea Subsurface

3D stress field modeling of the subsurface of the German North Sea and adjacent areas: Creation of numerical 3D simulations (poro-visco-elasto-plastic models as dynamic THM simulations) to assess the mechanical, thermal, and hydraulic state of the deeper subsurface. The goal is to derive the stress state, estimate the reactivation potential of faults or their new formation due to CO₂ injection, predict the pressure state, and define CO₂ injection strategies. The modeling covers the entire lithosphere (possibly upper asthenosphere) with high accuracy for the uppermost kilometers of the upper crust and consistent assumptions for deeper crustal and upper mantle areas. The execution and evaluation of the simulations are planned for approximately 2 years, plus a six-month lead time for coordination and preparation of the structural model by the client. Expertise in large-scale coupled thermo-hydro-mechanical issues and geodynamic modeling of the entire lithosphere is required.
