• Multidisciplinary syntheses on geoscientific data for charaterizing a geothermal resource in a given region;
• Geological monitoring of the cuttings, cores, logs from exploration and geothermal production wells;
• Geochemical monitoring of well fluids (water, gas), chemical and isotopic analyses of thermal waters and soil gases;
• Characterization, analysis, interpretation and modelling of fracturing in crystalline rocks for EGS and high-energy volcanic systems;
• Geophysical exploration of the high-energy resources using various methods (magnetotellurics, gravimetry, ground/airborne magnetism, coastal seismics, broadband seismics) to obtain 3D imagery of the geothermal fields;
• Surveillance of geothermal sites exploiting a high-enthalpy resource by geophysical methods (seismic, gravity, geodesic and electric).

• Development of computational tools and methods for the digital modelling of flows and underground transfers;
• Characterization, behaviour and impacts of systems exploiting the resources of deep aquifers;
• Thermo-hydrodynamic modelling (THM) of hydraulic stimulations for EGS using specific calculation codes;
• Design, development and follow-up of THM percolation experiments on fractured samples in the laboratory;
• Geochemical laboratory experiments (batch tests, column tests, etc.) for characterizing and understanding the water-rock-gas interaction processes that take place in geothermal reservoirs;
• Tracing tests with chemical tracers to assess the status of hydraulic connections between wells and also for estimating the capacity of the studied reservoirs and the circulation velocity of the fluids.
