Postdoctoral Research Position in Integration of Scale, Corrosion and Reservoir Souring Mitigations

Technical University of Denmark - Danish Hydrocarbon Research and Technology Centre

Location: Lyngby - Denmark
Salary: Not Specified
Hours: Full Time
Contract Type: Fixed-Term/Contract
Placed On: 7th February 2019
Closes: 7th March 2019

The Danish Hydrocarbon Research and Technology Centre, Technical University of Denmark (DTU), invites applicants for a multidiscipline postdoctoral position in the area of numerical modelling of biological proccesses in the subsurface.

Responsibilities and tasks

Biological hydrogen sulphide production in subsurface reservoirs and pipelines is an unfavourable phenomenon as leads to higher operational costs. The produced hydrogen sulphide is a toxic gas leading to health and safety issues; it also enhances infrastructure corrosion among other negative effects. The presence of scales (e.g. CaCO3, BaSO4, FeCO3, FeS) might lead to enhanced corrosion rates due to galvanic effects and fouling of equipment’s, which ultimately lower the production rates. Corrosion is a common problem in the oil and gas industry, which reduces the lifetime of oilfield equipment. 

The candidate will develope numerical models for coupled proccesses in chalk formations and the injection and production wells. He/She will investigate the interaction among different hydraulic, chemical and biological processes controlling the flow dynamic in the wells and the reservoir. A thorough sensitivity analysis on the effect of different mitigation plans on well and reservoir performance will be conducted. This will be then tested for data measured for the targeted field. The position will be an integrated part of the Scale & Corrosion programme with the focus on improving well integrity.  Co-supervising of Ph.D./MSc students working with reservoir simulation and collaboration with other researchers and students working with advanced water flooding experiments are required. The team will have access to unique field and laboratory data sets to test concepts and methods developed at the centre.  The candidate is expected to work with the team to perform innovative, fundamental, and applied research on:

  • Field scale analysis of altered injection water composition and physical conditions on the microbial souring and scale in the wells
  • Upscaling CFD and thermodynamic analyses for well models
  • Impacts of biocide and nitrate injection on the well flow
  • Combined effects of temperature, pressure and water compositions fluctuations on the well and reservoir performance

The project will involve work with DHRTC partners' research teams and with the team in the fluid characterization and recovery processes groups at DHRTC. 

Qualifications

  • PhD degree in mechanical engineering or other relevant areas;
  • Excellent Knowledge of the fundamentals of multiphase flow and transport in porous media and pipes;
  • A good knowledge of geomicrobiology, applied mathematic and CFD is very valuable.
  • Previous experience with devloping numerical codes for reactive transport models is highly advantageous.
  • Ability to work in a multi-disciplinary environment as an independent researcher;
  • Good writing and communication skills in English;

Application procedure:
Please submit your online application no later than 7 March 2019.
