PhD Position High-Resolution Modelling and Simulations of Low-carbon Geoenergy Applications

Updated: 2 months ago
Deadline: 29 Mar 2024

Would you like to join an interdisciplinary team that combines geoscience, reservoir engineering, and social science to enable the sustainable development of low-carbon geoenergy applications?

Geological reservoirs used for producing or storing energy are heterogeneous. Characterising and quantifying geological heterogeneities is challenging because sampling scales (e.g., plugs, cores) are different from the scales where petrophysical properties need to be defined (i.e., the grid block in a reservoir model). This gives rise to major uncertainties, especially in heterogeneous formations such as the Rotliegend of the Netherlands, because reservoir models are used to investigate how geological heterogeneities impact production rates and production risks. A fundamental challenge is that current reservoir modelling workflows almost always underestimate geological heterogeneity and hence provide unrealistic uncertainty bounds. The unique database of the Groningen Rotliegend reservoir in the Netherlands provides a once-in-a-generation opportunity to develop an efficient and scientifically-based methodology that allows us to represent the key geological heterogeneities in reservoir models through geologically-informed upscaling and better constrain uncertainties in model predictions. Such advanced geoscience research will enable us to execute future geoenergy projects safely and sustainably, and is needed to earn trust among different stakeholders and societal actors. The CrossScale project, which is part of the DeepNL programme funded by the Dutch Research Council, hence aims to bridge across scales and disciplines to develop a new upscaling methodology for better reservoir models and provide a new deliberation approach that improves the communication between scientists and societal stakeholders.

In this PhD project you will build advanced reservoir models needed for developing new upscaling methods and validating REV scales for geomechanical and fluid flow properties. This will result in an ensemble of high-resolution models (i.e., with millions of grid cells) that preserve the sedimentological and diagenetic heterogeneities identified for the Dutch Rotliegend. These models will be built in the Rapid Reservoir Modelling software, a unique reservoir modelling environment that allows us to construct realistic and high-resolution 3D reservoir models in a matter of minutes. The models will be built at the inter-well scale and will be subjected to coupled flow and geomechanical simulations using the state-of-the-art and open source reservoir simulators DARTS and the Matlab Reservoir Simulation Toobox. You will simulate coupled single-phase flow with geomechanics and two-phase flow processes relevant to CO2 and/or H2 storage. Based on these flow simulations and the result from the REV scale analysis, upscaling methods for coupled flow and geomechanical properties will be proposed. You will hence be able to answer the following research questions:

  • How can the REV scales be integrated into an upscaling methodology to improve the prediction of flow and geomechanical behaviours of the Rotliegend?
  • What are the key geological heterogeneities that need to be characterised to define REV scales and execute upscaling methods reliably for other geoenergy applications in the Rotliegend?
  • How will uncertainty bounds estimated from reservoir models of the Rotliegend change if reservoir modelling utilises new upscaling methods and REV scales?
  • Please check also the other PhD position in this project at University of Groningen and read more about DeepNL .

    The successful applicant project will hold a relevant MSc degree in applied geology, hydrogeology, or reservoir engineering. Ideally, this candidate will already be able to contribute some experience in integrating geoscience with fluid flow modelling or have a basic knowledge in simulating fluid flow and geomechanical processes in geological formations. Experience in upscaling or uncertainty quantification is also welcomed.

    Due to the interdisciplinary and collaborative nature of the CrossScale project that bridges across geoscience, reservoir engineering, and social sciences, excellent communication and interpersonal skills, as well as the desire to work in a diverse and interdisciplinary environment, are an essential requirement. The candidate should also have sound quantitative approach to subsurface geoscience challenges and bring some programming experience (e.g., Python).

    Are you enthusiastic about utilising the subsurface to accelerate the energy transition? Do you have a strong background in geology, hydrogeology, or reservoir engineering and feel that you are a good match for the position but cannot yet tick all the boxes? Then please still get in touch as we would like to hear from you and explore how you can learn and grow in this position.

    Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis.
