This dataset contains a high-fidelity three-dimensional (3D) reservoir model developed for numerical simulation using the CMG STARS reservoir simulator. The model is based on the geological framework of the Groß Schönebeck geothermal research platform and discretized into a Cartesian grid, which provides the numerical basis for thermo-hydraulic reservoir simulations. Key physical parameters, including rock petrophysical and fluid properties, have been incorporated into the model based on the interpretation of subsurface data acquired at the Groß Schönebeck site.
The dataset comprises simulator input files developed to model a closed-loop geothermal system using the existing wells E GrSk 3/90 and Gt GrSk 4/05. Two completion depths, 3,600 m and 3,800 m measured depth (MD), were evaluated to investigate the performance of a coaxial deep borehole heat exchanger (DBHE) system. The numerical simulations assess the effects of completion depth, circulation flow rate, and injection temperature on the thermal performance of the closed-loop system.
