The Materials and Surface Engineering section in the Department of Mechanical Engineering at the Technical University of Denmark is seeking candidate for 1 Postdoc or Research Assistant position for investigating corroded tubes from Oil & Gas applications for understanding the corrosion mechanisms and nature of scales. The position is initially for a period of 18 months. Proposed position is part of the work in collaboration between The Danish Hydrocarbon Research and Technology Centre (DHRTC) at DTU and Maersk Oil (MOG). Expected start date for the position is 1st of July 2017.

Responsibilities and tasks
Corrosion and scale formation is a serious issue in the oil and gas industry, which reduces the lifetime of oilfield equipment. An extensive internal corrosion in the wells often leads to costly interventions including replacement of used materials to corrosion resistant alloys. In the case of wells, workovers are performed, when the well integrity is at risk due to corrosion.

To prevent corrosion, e.g. corrosion inhibitors, H2S and O2 scavengers or biocides can be used. However, despite of using such mitigation techniques, extensive corrosion in wells is still observed. The conditions present in the wells are complex and the severity of corrosion depends on various environmental (e.g. CO2/H2S/O2, seawater fraction, temperature, pressure, liquid flow velocity, stresses etc.) and material variables (e.g. chemical composition, microstructure).   

Corrosion and scale formation leads to failure of pipe lines or reduction in the capacity for fluid flow due to reduction in internal dimensions due to scale formation. Therefore investigation of corroded tubes and scales from oil fields are important in developing remedial solutions. The intended position will focus on detailed characterization of corroded tubes and scales using characterization methods such as X-ray diffraction, high resolution electron microscopy and FIB, X-ray tomography, SKPFM, and other surface characterization and electrochemical methods. The focus will be to understand the general corrosion mechanisms, under deposition corrosion, effect of material chemistry and microstructure, and scale characteristics in comparison with well conditions.

Qualifications

Postdoc position:
Candidates should have a PhD degree in Materials engineering/Corrosion with expertise in material characterization and corrosion in Oil & Gas applications. Expertise on intended material characterization methods shown above is preferable.

Research Assistant position: Candidates should have a Master degree in Materials Engineering with experience on topics similar to postdoc position.  

Please indicate whether you are applying for Post-doc or RA position in your application.
