Two PhD positions in the field of chemical fingerprinting and reactive multiphase flow in cement

Individual research projects

The Danish Hydrocarbon Research and Technology Centre (DHRTC), Technical University of Denmark (DTU), invites applicants for two PhD positions in the field of chemical fingerprinting and reactive multiphase flow in cement. These two positions are closely linked within the same project and is part of a larger project portfolio relating to safe and sustainable abandonment of oil wells in the Danish North Sea Chalk reservoirs. DHRTC was established by the Danish Underground Consortium and DTU in 2014 as part of a national strategy for energy, the research Centre is an ambitious, targeted effort to improve recovery of hydrocarbons from the Danish North Sea sector. When the oil field approach the end of the production lifetime, the procedures of abandoning and safely closing the wells poses challenges to the materials involved. DHRTC has initiated a research program with a focus on solutions to the techniques and materials required to seal abandoned wells and the monitoring of closed wells.

Project 1 – Characterization of crude oil tracers by fingerprinting
This project will focus on the detailed chemical characterization and identification of specific compounds which can be used as tracers for hydrocarbon leaks in cement structures in wells. The chemical analysis will performed by spectroscopic techniques (IR and UV) and high resolution mass spectrometry (2D GC-TOF-MS and LC-HRMS) and other analytical techniques. The interaction between fluids and cement will be tested in conditions in flow experiments in the laboratory.

Project 2 - Reactive multiphase flow in cement
The project will utilize coupled simulations to address the fate and transport of multiphase flow from reservoir to well top side. The model will consist of a complex reaction network considering microbial activity and cement-steel-water-hydrocarbon and chemical interactions. The main purpose is to study the relevant processes that may occur during the transport of fluids from reservoir or overburden layers to the surface through annulus of the well.

Qualifications – PhD 1 Characterization of crude oil tracers by fingerprinting
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree in environmental, physical or analytical chemistry or similar fields.

• Experience with and interest in experimental chemistry;
• Experience from MSc level with chromatography,  mass spectrometry, IR spectroscopy, chemometrics and separation techniques
• Strong interest in applied research;
• Ability to work in a multi-disciplinary environment;
• Excellent writing and communication skills in English;

Qualifications – PhD 2 Reactive multiphase flow in cement

• M.Sc. degree in Chemical Engineering, Chemistry, Physics, Applied Mathematics,  Earth / Environmental Sciences or other relevant areas;
• Knowledge of the fundamentals of reactive flow and transport in porous media (e.g. cement) and wells;
• A good knowledge of geochemistry is very valuable.
• Practical experience with scientific programming languages and laboratory work are desirable
• Ability to work in a multi-disciplinary environment as an independent researcher;
• Good writing and communication skills in English;
