Internship | Impact of gas impurities on CO2 storage capacity in depleted gas fields and aquifers

About this position

This internship project aims to quantify the impact of gas impurities on the CO2 storage capacity of depleted gas fields and aquifer storage sites. This will be done by incorporating outcomes of experimental research on mixing gases with dynamic numerical simulations of potential CO2 storage sites.

What will be your role?

CO2 is highly compressible when injected to the depth and temperature range that is considered for CCS (Carbon Capture and Storage) projects. CO2 capture takes place at industrial sites where it is typically a waste gas that includes a small percentage of impurities. As the presence of impurities affect the phase behavior of CO2, including its density, viscosity, and phase transition points, they can significantly impact the injectivity, plume distribution and capacity of CO2 storage sites. This effect however is poorly constrained. Subsequently, mixing between CO2 and remnant hydrocarbon gasses adds another factor influencing the CO2 storage capacity in depleted gas fields.

You will use the range of gas impurities as defined for the Aramis and Porthos CO2 storage projects as the basis for dynamic subsurface modelling of the storage site using compositional simulation to define their impact at various conditions. Additionally, based on literature study of previous experiments and numerical modeling you will be able to benchmark these outcomes. Subsequently, you will use these results to analyze the potential impact of impurities on the CO2 storage capacity of the Dutch North Sea sector.

What we expect from you

We are looking for a master's student or a student who would use this topic for a master's thesis with the following profile:

  • Study: you are studying geosciences or (applied) physics. Any other field with knowledge and affinity for gaseous modelling in porous media is also welcome.
  • Language: English required, Dutch optional but desirable
  • Interests: Numerical modelling, Geoscience, Subsurface CO2 sequestration
  • Skills: Quickly grasping new concepts and identifying the most crucial aspects of a complex problem involving different expertise. Good math, and computing skills. Skilled in numerical modelling of subsurface processes or similar tools. Experience in dynamic reservoir modelling is an advantage.

The selection process

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

  • Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
  • Before the start of the internship, the educational institution will need to confirm in writing that:
    • 1) you are enrolled at the educational institution during the internship, and;
    • 2) the internship takes place as part of the programme of the study.
  • The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
  • Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
