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 oil recovery 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:
•Setting up an analytical laboratory for reservoir brine and petroleum fluid characterization
•Studies of rock-fluid interactions to understand the effect of different petroleum fluids and brines on wettability
•Selection of injection fluids for core flooding experiments on chalk samples from the relevant reservoirs
•Thermodynamic modelling of multicomponent ionic systems in relation to oil recovery

Water based enhanced oil recovery (EOR) employs different techniques to optimize the flow of oil and to minimize the residual oil left behind by the water flooding of oil reservoirs. A thorough analysis and characterization of the reservoir fluids is required for optimizing these techniques. A molecular characterization of the reservoir fluids provides the link between well-established models for mixtures of simple molecules and improved models for reservoir fluids that consist of many complex components and ill-defined fractions. The characterization will be based on modern analytical methods including NMR, FTIR, HPLC, GC-MS to identify individual molecular components in reservoir fluids which consist of many hundreds of distinct compounds.

Advanced molecular analysis will also provide information on polarity and functionality of fluid constituents which is not provided by standard oil characterization methods. This data will support mathematical characterization methods such as modelling of PVT properties and various lumping/delumping methods. In addition, the project will provide valuable input for rock surface chemistry studies, corrosion studies, core flooding experiments, and reservoir simulation. The team will be responsible for setting up the laboratory and assisting with the installation of instrumentation for analysis of oil samples from the Danish North Sea. Close collaboration with colleagues across the centre’s scientific themes as well as external partner institutions is an integral part of the work at the centre.

Application potential
The line-of-sight application potential of this project is to assist the screening processes of potential water based recovery methods in the Kraka, Dan, and Halfdan oil fields.

Qualifications

•PhD students: M.Sc. degree in analytical or physical chemistry, chemical engineering or similar;
•Postdocs: PhD degree in analytical or physical chemistry, chemical engineering or similar;
•Exceptional skills in experimental chemistry;
•Interest in applied research;
