Demonstration of soft stimulation treatments of geothermal reservoirs: Developing stimulation techniques to enhance reservoir productivity while minimising environmental risks

The Destress project’s main objective is the development of EGS stimulation technology that significantly improves the productivity of deep geothermal systems while reducing risks to the environment.

The project examines the implemention, analysis, and modelling of innovative stimulation techniques at 8 geothermal drilling sites located in Europe (Germany, France, Holland, Lithuania, Switzerland) and South Korea.

Two University of Strasbourg departments, EOST and LISEC (Laboratoire interuniversitaire des sciences de l’éducation et de la communication), participate in the Destress project. EOST studies the development and exploitation of deep geothermal reservoirs post-stimulation using a multipdisciplinary approach that merges seismology, geodesy, rock mechanics, and the study of water-rock interactions. These studies are carried out in the laboratory, in the field (at the sites of Soultz-sous-Forêts and Rittershoffen) and via numerical models. LISEC studies the social acceptability of soft-stimulation activities in Alsace.
