LIAG seminar: Investigation of the hydrochemical effect on the sustainability of a geothermal plant in a critically stressed fault

LIAG welcomes all interested parties to its biweekly LIAG seminar, featuring exciting presentations on research and technology, held on Tuesdays at 11:00 a.m. at the Geozentrum Hannover or online via Webex. The presentations, with a duration of roughly 30 minutes, are followed by a discussion and are held in either German or English, depending on the announcement. The entire programme is published by LIAG.

On Tuesday, 28 October 2025, Mohamed Thoronka will give a presentation in English on the topic: 

Investigation of the hydrochemical effect on the sustainability of a geothermal plant in a critically stressed fault and fracturecontrolled carbonate reservoir: A case study of Poing

Abstract: This study explores thermo-hydro-mechanical-chemical (THMC) processes in the Upper Jurassic aquifer, using the Poing geothermal field near Munich as a case study. A simplified 3D reservoir model is developed and converted into a volumetric representation for finite-element simulations to analyze water–rock interactions and their impact on reservoir stability. Coupled simulations with PHREEQC, COMSOL Multiphysics®, and iCP are employed, alongside sensitivity and uncertainty analyses, to evaluate the potential for induced seismicity.
