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.
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.

The overarching purpose of The Danish Hydrocarbon Research and Technology Centre is to identify new technological and conceptual solutions that will enable increased oil and gas extraction in the Danish section of the North Sea. The research activities at the centre cover selected aspects of expertise: Reservoir characterization, Enhanced Oil & Gas Recovery Processes, Drilling & Production Technology Concepts and Production Facilities, Materials Research & Design. The centre will develop deep, new understanding within these disciplines with a line-of-sight to application. Located at The Technical University of Denmark research groups at the University of Copenhagen, Aarhus University, Aalborg University and the Geological Survey of Greenland and Denmark will be affiliated with the Centre. When fully operational, the centre will employ and engage more than 100 people.
