GFZ is Germany's national centre for solid Earth research. We advance the understanding of dynamic processes to address global challenges, from mitigating the impacts of natural hazards and sustaining our habitat amid global change to responsibly managing georesources. We are part of the Helmholtz Association, the largest German scientific organisation. With around 1,200 employees as well as ca. 500 guest researchers, we contribute to the Helmholtz Research Field Earth and Environment, aligning cutting-edge research with societal relevance and international collaboration. Our work integrates multidisciplinary studies across Earth's system components, leveraging advanced technologies and infrastructure to research solutions and to transfer our knowledge to society. We are doing this according to our vision: "Taking the pulse of our Earth to safeguard a habitable planet”.
PhD student (f_m_x) – Coupled process simulations for a geothermal field in the Upper Rhine Graben
Reference Number 10639
– The position is dependent on the approval of the project. –
Join our collaborative project "ConvEx” and become an active contributor to the renewable energy transition! Failed geothermal projects due to "drilling dry” or induced seismicity in the Upper Rhine Graben – a region of high temperature gradients on the border between Germany and France – point to an insufficient knowledge about the hydraulic and mechanical conditions in the subsurface. Despite the abundance of seismically imaged faults and fractures, identifying those that are highly permeable but mechanically subcritical to guarantee economic viability and sustainability of hydrothermal geoenergy projects is a significant challenge. The advertised position involves conducting numerical simulations of coupled thermo-hydraulic-mechanical (THM) processes based on various observational datasets (e.g., hydrogeological structure, borehole pressure and temperature). The major goal of the project is to develop Digital Twins for a geothermal exploration field in the central Upper Rhine Graben, which will help us answer "what-if?” questions for multiple exploration scenarios.
Your responsibilities:
- Data and model preparation: Gather and revise existing 3D models, petrophysical data, borehole measurements, operational and monitoring data to build a DT (Digital Twin) of the exploration field "Lionheart”
- Conduct THM simulations and perform history matching and further testing of production scenarios for geothermal doublets
- AI-interpretable assisted surrogate modelling for sensitivity and uncertainty analyses
- Presentation of the results at conferences and publication in peer-reviewed journals
Your qualifications:
- A Master's degree (or equivalent) in geosciences, geophysics, computational sciences or related subjects
- Experience in the fields of geophysical data analysis, rock physical properties and numerical process simulations
- Provable programming skills in Python/C++
- Capacity for interdisciplinary and international teamwork and excellent communication skills
- Very good English language skills
What we offer:
- Ambitious and varied tasks in a dynamic and international research environment
- State-of-the-art equipment
- Public service benefits
- Extensive training opportunities
- Professional career advice offered by our in-house Career-Centre
- Flexible working hours and conditions
- Support with finding a good work-life balance offered by benefit@work
- Institute day-care centre on site
- Working at the Albert Einstein science park on the Telegrafenberg in Potsdam
- Work place within walking distance of Potsdam main train station, or just a short ride on the shuttle bus
Fixed-term: 36 months
Salary: The position is classed as salary group 13 according to "TVöD Bund (Tarifgebiet Ost)”. The salary group is determined on the basis of the Collective Wage Agreement and the respective personal qualifications.
Working hours: Part-time 75% (currently 29.25 h/week)
Place of work: Potsdam
