Challenge: Coupling subsurface properties and geothermal fluid temperatures.

Change: Improved simulations and monitoring options of geothermal systems.

Impact: Better managing energy resources.     

Job description
Geothermal systems have the potential to significantly reduce CO2 emissions, but characterising and monitoring them effectively is key. Electromagnetic geophysics can be used to monitor geothermal systems as changes in subsurface temperatures are linked to differences in electrical resistivities. However, challenges like electromagnetic noise and not well-defined physical relationships between resistivity and aquifer temperature require innovative solutions to obtain precise measurements and characterise reservoir behaviour; i.e. locations and intensity of temperature contrasts and changes over time.

As a PhD candidate, you will contribute to geothermal system monitoring through:

• Demonstrating and improving electromagnetic monitoring in urban areas.
• Validating and refining the empirically derived resistivity-temperature relationship for water-bearing rocks.
• Devloping combined heat transfer and electromagnetic simulations to enhance the understanding of geothermal systems.

Your research activities will comprise running numerical simulations, contributing to existing modelling codes, participating in field works and conducting laboratory experiments. You will work closely with colleagues from the Geoscience and Engineering Department of TU Delft and engage with a divers team of international partners.

This PhD project is linked to the TU Delft High-Temperature Aquifer Thermal Energy Storage (HT-ATES) site within the framework of the PUSH-IT (Piloting Underground Seasonal Heat Storage in Geothermal Reservoirs) project. Therefore, this PhD position presents an exceptional opportunity for engagement with the international PUSH-IT community, characterised by both the availability of data and the tangible impact of actively mitigating CO2 emissions through the utilisation of the seasonal heat storage infrastructure.

At TU Delft, we offer a supportive and inclusive working environment that values international collaboration, innovation, and work-life balance. If you’re enthusiastic about combining science, innovation, and societal impact, we’d love to hear from you. Join us in shaping a more sustainable future!

Requirements
We are looking for a motivated and knowledgable PhD candidate to join our team. To thrive in this role, you

• Hold or are about to complete an MSc degree in geophysics, geoscience, reservoir engineering, applied physics, or a related field.
• Have a solid understanding of electromagnetic geophysical theory and basic geology.
• Are proficient in at least one high-level programming language.
• Are interested in conducting field and laboratory work.
• Are open to interdisciplinary approaches and collaborative research.
• Are keen to grow to become an independent researcher in the field of electromagnetic geophysics.

Experience with numerical simulations, data assimilation techniques, and familiarity with low-level programming languages and software development are welcomed, but no must-haves. If you are ready to learn, we will support you!

In addition, excellent communication and interpersonal skills are an essential component for this position. Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate can communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements.

Are you enthusiastic about electromagnetic monitoring of geothermal systems? Do you have a strong background in geophysics and feel that you are a good match for the position but cannot yet tick all the boxes or need some time to finish your MSc degree? Then please still get in touch with us as we would like to hear more about your vision for this project and are keen to learn how your skills could contribute to the planned research.

We are acutely aware that we are a diverse society and not every talented student will have had the same opportunities to advance their careers. We will not discriminate against individual circumstances (e.g. parental leave, caring duties, disabilities etc.) to ensure an inclusive and fair recruitment process. We will also consider a wide range of possible career paths, not only common research metrics.
