PhD Position Hydrogeochemical Processes Affecting Efficiency during Operation

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 ITN EASYGO, funded by the European Commission, the IDEA League universities TU Delft (TUD), ETH Zurich (ETH), RWTH Aachen University (RWTH), Politec- nico 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 tomorrow’s leading geothermal energy experts.
EASYGO is seeking 13 highly qualified and enthusiastic individuals holding a relevant Master degree (or equivalent) to conduct state-of-the-art research within the projects specified below. Please find additional information on EASYGO as well as detailed project descriptions here and do not hesitate to contact the associated supervisors in case of questions. Successful applicants will conduct their research work at two universities and in close collaboration with industrial partners. They will also benefit from the various training and networking opportunities within the ITN and large-scale infrastructure by the consortium partners across Europe.

This PhD study will focus on geohydrochemical processes, that are often responsible for decreasing production or injection rates. Clogging processes can be divided into (1) physical, (2) chemical, and (3) biological processes and be studied by analysing fluid and solid samples as well as operational data. We aim to monitor and investigate hydrogeochemical processes and their interaction in real time at geothermal sites. Monitoring will take place during production and cold injection in the reservoir as well as in the surface infrastructure on-site. Modeling thermo-hydraulic-geochemical processes will be an integral part of the study. Concepts will be developed to avoid hydrogeochemical processes negatively affecting efficient long-term operation. Eventually, data from different geothermal sites will be compared in the Netherlands in cooperation with the industry partner Hydreco Geomec.

Secondment stays of several months are foreseen at ETH Zurich to further investigate hydrogeochemical processes with a focus on the influence of CO2 in the reservoir/CO2 injection and with the industry partner Hydreco Geomec to compare results with data from geothermal reservoirs across Netherlands.

As a PhD candidate, you will be enrolled in the TU Delft Graduate school. TU Delft's graduate school provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.

We seek a candidate with an MSc degree in (preferably) geoscience/(hydro)geology and with proven excellence in physical and mathematical thinking. Moreover, the candidate should be a good communicator, have broad interests and learn quickly.

Previous knowledge or experience in hydro/geochemistry, geothermal data interpretation would be advantageous.

In particular, we are looking for a candidate with the following knowledge and skills:

  • Independent, self-motivated, reliable, and eager to learn.
  • Ability to work in a project team and take leadership and responsibility for different research tasks.
  • An excellent command of English and good academic writing and presentation skills.

If your mother language is not English and you do not hold a degree from an institution in which English is the language of instruction, you must submit proof of English proficiency from either TOEFL (minimum total score of 100) or IELTS (minimum total score of 7.0). Proof of English language proficiency certificates older than two years are not accepted.
