Numerical Model of a Geothermal Project in the Northern Upper Rhine Valley

The subsurface of the northern upper Rhine valley is a potential geothermal reservoir. Interpretation of 2D and 3D seismic data, supplemented by well data is the base for a static 3D model. Further integration of lithologic information from outcrop studies and well cores leads to a facies distibution of the study area. Transfer of stratigraphic and structural data to a finite element program allows the simulation of hydraulic and thermal developement while 25 years of production. Especially the production in a fault zone with a high throw and good permeability predicts very good usability of the geothermal reservoir units.
