The Department of Chemical and Biochemical Engineering, Center for Energy Resources Engineering (CERE), invites applicants for a PhD or postdoc position in Barite Scale Formation at Well Conditions. 

CERE is Denmark’s leading research center in the areas of EOR, flow assurance, CCS and petroleum geoscience. CERE is an independent, university based, research unit with more than 30 years of expertise in the field. The CERE co-workers are a mix of internationally renowned scientists and the sharpest young talents from different scientific communities around the world.

Scale formation in the production equipment of the oil and gas industry poses a general challenge. It tends to build up on the interior pipe wall both downhole and in the upper part of the well and production tubular. A significant amount of scale will eventually precipitate which can cause a failure of downhole safety valves or a complete stop of production due to loss of internal diameter of the pipe from excessive scale formation. Scales may also cause under deposit corrosion and there is a great need to understand why and where the scales are formed. The objective is to reduce the cost of well workovers by developing better methods to predict scale formation. The scales in focus during this study is BaSO

Responsibilities and tasks
The aim of this study is to measure the solubility of BaSO4 under well conditions and to fill in the gaps between the data published in the open literature. In some temperature and pressure ranges, previously published data for BaSO4 solubility from different sources are not in agreement. Existing thermodynamic models at DTU are available for supporting the design of experiments.

In this project you will:

  • Further develop existing equipment and analytical methods.
  • Construct a new equilibrium cell that can withstand temperatures up to 200 °C and pressures up to 50 MPa.
  • Measure BaSO4 solubility under varying conditions such as temperature, pressure, and brine composition.
  • Use the new data generated in this project for improving thermodynamic models so that scale formation can be better predicted in the future.
You will have the chance to visit external research institutions to gain knowledge on the topic.


PhD position:
Applicants for PhD scholarship 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. The Master’s degree should be in analytical or physical chemistry, environmental sciences or similar.

Postdoc position:
  Applicants for the Postdoc position should have a PhD degree in analytical or physical chemistry, environmental sciences or similar. In addition, we look for applicants with: 
  • Exceptional skills in experimental physical chemistry/chemical engineering/environmental science;
  • Experience with and a strong interest in setting up advanced experiments;
  • Interest in applied research;
  • Ability to work in a multi-disciplinary environment;
  • Excellent writing and communication skills in English;
Approval and Enrolment 
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.  

The assessment of the applicants will be made by Associate Professors Philip L. Fosbøl and Kaj Thomsen.
