Job description

The research of the Division of Geothermal Energy and Reservoir Technology at the Institute of Applied Geosciences at KIT focuses on reservoir characterization, exploration and engineering in deep geothermal applications. The projects are conducted at a national and international level with numerous partners and application fields worldwide.

One key aspect of research in this domain is the experimental and numerical investigation of fluid flow within rough and sheared fracture geometries at high flow rates which are typical for geothermal production in the near wellbore region.

The surface roughness in interaction with high flow velocities can cause turbulent flow conditions. In such complex flow regimes, key questions regarding hydraulics, transport processes, and effects on fluid chemistry are still unsolved. To address these questions, the F4aT-laboratory (Forced Fracture Fluid Flow and Transport) was established. The hydraulic test lab comprises a 3D scanner to determine the topology of rock surfaces. Based on this data, fracture samples for hydraulic testing are fabricated using a 3D printer. This setup provides the unique opportunity to perform hydraulic tests with a large number of statistically identical samples in order to derive robust results. THMC models will be developed to numerically validate the results and bridge the scale to geothermal reservoirs.
