stillingsbetegnelse: PhD positions in advanced oil recovery processes

jobbeskrivelse:
The Danish Hydrocarbon Research and Technology Centre (Centre for Oil and Gas – DTU), Technical University of Denmark (DTU), invites applicants for experimental PhD positions related to the investigation of oil recovery methods and their mechanisms in the context of advanced water flooding. Centre for Oil and Gas – DTU has been established by the Danish Underground Consortium and DTU. As part of a national strategy on oil and gas, the research centre has an ambitious, targeted effort to improve the recovery of oil and gas from the Danish North Sea. The first programme in the centre will investigate 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 tight chalk reservoirs in the Danish part of the North Sea. In this context, the candidates are expected to perform innovative, fundamental, and applied research on: •Water-based recovery processes, e.g. SmartWater, surfactant, solvent, and microbial EOR methods. The processes should be studied by utilising core flooding experiments under reservoir conditions. •The flooding potential in fracture-matrix dominated reservoir systems by spontaneous and forced imbibition experiments. •Contribution to increased system understanding through integration of core flooding, core scale models, fluid characterization 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, reducing residual oil saturation. 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 effluent analysis are some of the key challenges. In the interpretation of the experiments, you will use your knowledge with chemistry and transport processes and link it closely to the wettability studies and the oil-water characterization studies that are carried out in our centre. The results from core flooding experiments will be used to improve the models both at core and reservoir scale. You will be a part of the team working with recovery processes at core scale, working closely together with other PhD students and Postdocs. 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 •M.Sc. degree in chemistry, chemical or petroleum engineering, 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 Approval and Enrolme
