Postdoc position in thermodynamic modelling of SmartWater

jobbeskrivelse:
The Danish Hydrocarbon Research and Technology Centre (Centre for Oil and Gas – DTU), Technical University of Denmark (DTU), invites applicants for a Postdoc position in thermodynamic modelling. 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 research programmes of the centre is advanced water flooding of the Dan, Halfdan, and Kraka oil fields. This project is a collaboration with DTU Chemical Engineering which will be the main place of work. Responsibilities and tasks The positions will be an integrated part of the advanced water flooding programme with the focus on EOR methods for improving oil recovery in chalk reservoirs in the Danish part of the North Sea. The project will provide valuable input for rock surface chemistry studies, corrosion studies, core flooding experiments, and reservoir simulation. The Postdoc is expected to perform innovative, fundamental, and applied research on: - 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 - Study salt solubilities at reservoir conditions Enhanced Oil Recovery (EOR) techniques can be used to produce an additional 10-15% of the initially available hydrocarbons after primary and secondary recovery. One method is SmartWater flooding where concentrations of selected ions in the injection water are varied. There is some experimental evidence that salinity altered injection water is an effective EOR method in sandstone, however the effect in carbonates and the exact mechanism is not clear. The increased oil recovery is often attributed to wettability alterations of the rock, which can be caused by exchange of positive ions with the CaCO3 or by adsorption of negatively charged ion on the rock surface. When changing the ionic composition of the water the exact conditions for precipitation of salts and fines formation have to be investigated. Speciation calculations will be conducted for different proposed SmartWater compositions to assist with core flooding experiments with the aim to find an effective SmartWater for carbonate reservoirs. 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 - Ph.D. degree in physical chemistry, chemical engineering or similar - Experience with computational chemistry and programming desirable - Interest in applied research - Ability to work in a multi-disciplinary environment - Good writing and communication skills in English We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and terms of employment The appointment will be based on the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union. The period of employment is 2 years with the possibility of a 1 year extension.
