PhD student and Postdoc positions - Research Team for Experimental Studies of EOR/IOR Processes

jobbeskrivelse:
The Danish Hydrocarbon Research and Technology Centre (Centre for Oil and Gas – DTU), Technical University of Denmark (DTU), invites applicants for positions on investigations of recovery methods and their mechanisms in the context of advanced water flooding. Centre for Oil and Gas – DTU is established by the Danish Underground Consortium and DTU. As part of a national strategy on oil and gas, the research centre is an ambitious, targeted effort to improve recovery of oil and gas from the Danish North Sea. The first of the cross-disciplinary flagship programmes of the centre is advanced water flooding of the Dan, Halfdan, and Kraka oil fields. Responsibilities and tasks The positions will be an integrated part of the advanced water flooding programme with the focus on improving oil recovery in chalk reservoirs in the Danish part of the North Sea. In this context, the team is expected to perform innovative, fundamental, and applied research on: •Water-based recovery processes, e.g. SmartWater, surfactant, and microbial EOR methods •Studies of rock-oil-brine interaction and wettability to improve the understanding of the mechanisms contributing to increased recovery in chalk reservoirs •The flooding potential in fracture-matrix dominated reservoir systems •Contribution to increased system understanding through core flooding and wettability studies Water based enhanced oil recovery (EOR) employs different techniques to optimize the displacement of oil and to minimize the residual oil left behind by the water flooding of oil reservoirs. SmartWater processes involve changes in the ionic composition of the injection brine during water flooding of oil reservoirs, while adding surfactants lower the oil-water interfacial tension to mobilize oil. Microbial EOR can improve oil recovery by different mechanisms, e.g. reduced residual oil saturation or improved sweep efficiency due to selective plugging of fractures and high permeability zones. To better understand and to test the hypotheses for the advanced water-based recovery processes in chalk reservoirs, laboratory flooding experiments under reservoir conditions should be carried out. High-precision measurements of flooding effluent production and characterization of effluents are some of the key challenges. The understanding of rock-fluid interactions and wettability alteration will provide information to interpret the flooding experiments, improve the simulation models at both core and reservoir level. The team will be responsible for establishing the flooding facilities and assist in upscaling of models from core to field scale. Co-supervising of PhD /M.Sc. students working with flooding experiments and collaboration with other researchers and students working with oil characterization and modelling are expected. The team will participate in a growing cross-disciplinary research program, involving several researchers at DTU and other Danish universities, research institutes and industry. The team will have access to unique field and laboratory data sets to test concepts and methods developed at the centre. Application potential The line-of-sight application potential of this project is to participate in the screening processes of potential water-based recovery methods in the Kraka, Dan, and Halfdan oil fields. Qualifications •PhD students: M.Sc. degree in chemical or petroleum engineering, technical physics, or other relevant areas; •Postdocs: PhD degree in chemical or petroleum engineering, technical physics, or other relevant areas; •Excellent laboratory skills; •Knowledge of the fundamentals of flows and fluid distribution in porous media; •Interest in applied research; •Skills in mathematics and physics; •Ability to work in a multi-disciplinary environment •Good communication skills in English; For the PhD position The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree pro
