The Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association we are part of the largest German scientific organization. With around 1,300 employees (including our guests) we develop a sound understanding of the systems and processes of the solid Earth as well as strategies and options for action to face global change and its regional impacts, to understand natural hazards and reduce associated risks, and to assess the influence of humans on the Earth's system.
As a partner in Geo.X, the GFZ has access to an excellent network of other geoscience institutions in Potsdam and Berlin. This largest regional concentration of geoscientific competence in Europe offers first-class cooperation and development opportunities.
For the recently established Helmholtz Young Investigator Group "Advanced reservoir engineering concepts for a controlled utilization of deep geothermal energy in urban areas (ARES)" in Section 4.8 "Geoenergy" we invite applications for a:
The research group develops concepts and workflows for enhancing the hydraulic performance of deep geothermal reservoirs while minimizing environmental impacts such as induced seismicity ("soft stimulation treatments"). Research methods include experiments at laboratory, mine, and field scale as well as numerical modelling studies. We pursue our research in tight interdisciplinary collaboration across scales and across disciplines together with national and international partners.
The PhD student will improve numerical modelling codes and workflows and perform numerical proof-of-concept studies of hydraulic soft stimulation treatments. This involves quantification of the hydraulic, mechanical, and seismic response of specific geological settings to different fluid injection schemes and other operational constraints. Emphasis will be put on the differentiation between the effects of individual engineering parameters and geological boundary conditions as well as the upscaling of the results from laboratory scale to field scale. The results will improve the physical understanding of hydraulic stimulation treatments and associated fracture development, permeability increase and injection-induced seismicity. This will support the improvement of reservoir stimulation concepts to develop Enhanced Geothermal Systems (EGS) in a safe and economic manner.
