PhD Reservoir Simulation of Underground Hydrogen Storage (UHS) in Depleted Hydrocarbon Fields

PhD Reservoir Simulation of Underground Hydrogen Storage (UHS) in Depleted Hydrocarbon Fields

Challenge: Describe and model the reservoir for underground hydrogen storage.
Change: Protocols for safe and reliable UHS. Impact: Reliable and society-accepted energy transition.

Job description

The Dutch government has funded the HyTROS consortium to investigate and enable Hydrogen Transport, Offshore and Storage in the Netherlands. The consortium consists of 11 universities, 2 research institutes, 2 universities of applied sciences, and 19 industrial partners. As part of the Task “Large-scale hydrogen storage” of HyTROS consortium, the Department of Geoscience and Engineering at TU Delft is seeking to recruit a fully funded PhD position for 4 years. The PhD candidates will work on underground hydrogen storage (UHS) in depleted hydrocarbon fields, specifically on field-scale characterization, performance analyses and monitoring of UHS to enable its efficient and secure operation in a potential pilot site. The successful applicants will work in close cooperation with each other under the supervision of researchers from the sections and Reservoir Engineering and Applied Geology. The PhD project will concentrate on utilization of reservoir simulations for the quantification of the dynamic behaviour of cyclic storage of hydrogen in field-relevant scenarios with the aim to assess the purity and recoverability of hydrogen as well as reservoir containment.

Objectives:

• Design ensembles of reservoir models for UHS that capture the different scales of heterogeneity and their associated geological and conceptual uncertainties.
• Designing reliable dynamic simulation systems, by including appropriate UHS-relevant parameters, functions, and constitutive laws.
• Perform dynamic reservoir simulations (incl. geomechanics and chemical reactions) to provide probabilistic assessments of cyclic UHS and identify the key geological uncertainties as well as the multi-scale geological characteristics that are first-order controls on the reservoir behaviour during cyclic UHS.
• Perform a value-of-information analysis to investigate how improved geophysical monitoring could help constrain uncertainties in reservoir characterisation and the associated dynamic behaviour, and ultimately optimise the operation of UHS.
• Develop operational protocols for safe and optimal cyclic storage and withdrawal which are based on the improved understanding of the impact of reservoir uncertainties and geological heterogeneities on reservoir (in cooperation with other project team members).
• Provide pathways to develop a computational framework for real-time data integration in simulation models to guide decision-making for storage safety and performance optimization (in cooperation with other project team members).

To achieve the objectives stated above we foresee the following activities:

• Review and identify the relevant geological, petrophysical, geomechanical, and chemical data for UHS projects in depleted hydrocarbon reservoirs offshore and onshore Netherlands.
• Familiarization with advanced, multi-scale reservoir model design to build meaningful ensembles of reservoir models for UHS.
• Further development and utilisation of in-house open-source codes to simulate the dynamic behaviour of cyclic UHS considering geomechanical and chemical effects.
• Application and advancement of robust uncertainty and value-of-information analysis to investigate how better seismic monitoring reduces uncertainties and improves the safe and efficient operation of UHS.
• Development of data integration approaches that link static and dynamic reservoir simulators.

Job requirements

• The successful applicant will hold a relevant MSc degree in applied geoscience and engineering, with background on geology and reservoir simulation.
• Applications from MSc holders of related engineering domains will be certainly welcomed too.
• Having strong numerical and programming skills for forward and/or inverse problems are advantageous.
• Communication and interpersonal skills are essential to conduct the project successfully.
