Institute for Applied Geophysics and Geothermal Energy
Given the challenges in geothermal operations and the ambitious expansion plans for geothermal energy in many countries, there is an urgent need for experts with a broad understanding of geothermal systems. How can such systems be operated in the most efficient and safe manner? Within the Marie Curie Innovative Training Network EASYGO - Efficiency and Safety in Geothermal Operations, funded by the European Commission, the IDEA League universities TU Delft (TUD), ETH Zurich (ETH), RWTH Aachen University (RWTH), Politecnico di Milano (PoliMi) and 10 industry partners are addressing this question from different perspectives, integrating geology, geophysics, geochemistry, advanced modeling and process engineering. In this framework, EASYGO is looking forward to train tomorrows leading geothermal energy experts. Please find additional information on EASYGO as well as detailed project descriptions of all 13 PhD positions on www.idealeague.org/geothermal-energy. In case you want to apply for multiple EASYGO positions, limit the number of applications to 3, and indicate other positions you have applied for together with a clear order of preference in your motivation letter.
In this project, the successful applicant will conduct cutting-edge research work at the interface of model- and data-driven geophysical inversion in the context of geothermal reservoir characterization. Imaging of geological structures with sharp parameter changes across layer boundaries is challenging using conventional smoothness-constrained inversion of geophysical data sets. Advanced regularization approaches consider constant geostatistical properties throughout the parameter domain and therefore fail to capture the complexity of 3D geological models including fault networks, fault-surface interactions, unconformities and dome structures. In light of these challenges, the candidate will evaluate geometry-based inversion using an implicit potential-field interpolation approach for an optimized representation of complex 3D reservoir models with low parametrizations. Geophysical observations and geological prior knowledge will be used in a hybrid approach between model- and data-driven inversion quantifying the overall uncertainty of the system. The work will leverage on existing open-source software packages in geological modeling (e.g., GemPy, www.gempy.org) and geophysical inversion (e.g., pyGIMLi, www.pygimli.org).
The research will mainly be conducted at the Institue for Applied Geophysics and Geothermal Energy at RWTH Aachen University (with research visits at ETH Zurich and industry partners). Our main research foci are numerical reservoir simulation, petrophysics, and applied geophysical imaging of the shallow subsurface with electromagnetic methods. We combine high-performance numerical process simulations with petrophysical data measured in the laboratory and in boreholes. Applications are manifold and include geological reservoir engineering for geothermal energy, geological CO2 storage, and hydrological applications. The team consists of about 20 people, from which scientists (Postdoctoral researchers, PhD students) represent three quarters and administrative and technical staff represent one quarter.
You can expect a very diverse and challenging job in an international and multidisciplinary work environment. RWTH Aachen University is part of the ABC/J Geoverbund and therefore well connected with Colonge and Bonn Universities and the Forschungszentrum Jülich. RWTH is an equal opportunity employer. Therefore, we specifically encourage applications of qualified women and minorities.
