During the Vendenheim deep geothermal project (Strasbourg Eurometropole, France), large induced seismic events led to the arrest of the project. Two important features of the induced seismicity were unexpected: the large distance to the wells of a cluster of seismic events (4–5 km) and the occurrence of the largest event Mlv3. 9 at the bottom of the wells, six months after shut-in. To better understand the natural hydro-thermal conditions at the Vendenheim site, we develop within the framework of the DT-GEO project (Horizon Europe) a simplified large-scale model (8 km × 8 km × 6 km) of the area. We aim at performing in-silico experimentation to reproduce the natural hydrothermal state of the geothermal reservoir related to the heat flow (conductive/convective) within the model. We first test our methods by solving 2D and 3D benchmarks related to the convective regime in saturated porous media. Our model is based on the MOOSE/GOLEM framework (finite element approach) and integrate the public regional geological model GEORG that includes major lithologies. We present the coarse-grained simulations of the natural fluid circulation.
