Fluid–rock interactions and evolving thermodynamic conditions strongly influence the performance and sustainability of geothermal reservoirs, particularly through dissolution, precipitation, and scaling processes. Current reactive transport models often fail to capture long-term hydrochemical dynamics under realistic geothermal conditions. This research aims to develop robust thermo-hydro-chemical (THC models for geothermal reservoirs in the North German Basin by integrating geological, geophysical, and hydrochemical data. Using COMSOL-iCP-PHREEQC and/or FEFLOW-piChem-PHREEQC, reactive transport will be analyzed under both equilibrium and kinetic approaches to assess key hydrochemical controls on reservoir quality and energy production. Fit-for-purpose models and field validation with test wells from Baker-Hughes in Celle region will support uncertainty quantification and mitigation strategies, providing transferable insights into sustainable geothermal utilization under varying physical conditions and various operating cycles.
