PhD position for Experimental investigations of barite scale formation kinetics at well conditions

The Danish Hydrocarbon Research and Technology Centre (Centre for Oil and Gas - DTU), Technical University of Denmark (DTU), invites applicants for a PhD position for experimental studies of the kinetics of formation of the type heavily soluble scales that are observed in Danish North Sea production wells. 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 advertised project focuses on scale deposition studies of barite scale and other insoluble scales.
- Setting up a reaction cell to study scale build up
- Investigation of scale build-up and the dependence on flow, concentrations and temperature.
- Investigation of the effect of crude oil chemistry on scale

The position will be an integrated part of the scale and corrosion programme at the DHRTC which is focused on characterization, prediction and mitigation strategies for insoluble scales and corrosion in Danish North Sea oil wells In this context, the candidate is expected work with the team to perform innovative, fundamental, and applied research on:

When well integrity is at risk, the recovery Deposits of scale and corrosion are contributing factors for potential loss of well integrity and further, scale build-up causes decrease of well efficiency. EOR schemes may affect the rate of scale precipitation and corrosion, potentially to the point of negating the targeted improvement in recovery factor. Therefore, improved understanding of observed mechanisms and development of testing methods as well as improved modelling tools for predicting and potentially mitigating scale deposit and corrosion is essential for optimal recovery of the remaining reserves. The DHRTC research programme on scale aims to improve the understanding of the complex and coupled chemical mechanisms that govern the deposition of scales (e.g. CaCO3, BaSO4, FeCO3, FeS). The plan for this project is experimental studies of the kinetics of formation of BaSO4 and other insoluble scales with focus on nucleation and flow regimes. The project will focus on setting up a flow cell to simulate realistic pipe flow wherein the factors influencing scale build-up can be controlled.

The project will involve work with partner laboratories at DTU and with the team in the fluid characterization and group at DHRTC.

Application potential

The line-of-sight application potential of this project is to assist in reaching a better understanding of the conditions that lead to scale build up in North Sea Oil Well conditions

The overarching purpose of The Danish Hydrocarbon Research and Technology Centre is to identify new technological and conceptual solutions that will enable increased oil and gas extraction in the Danish section of the North Sea. The research activities at the centre cover selected aspects of expertise: Reservoir characterization, Enhanced Oil & Gas Recovery Processes, Drilling & Production Technology Concepts and Production Facilities, Materials Research & Design. The centre will develop deep, new understanding within these disciplines with a line--of--sight to application. Located at The Technical University of Denmark research groups at the University of Copenhagen, Aarhus University, Aalborg University and the Geological Survey of Greenland and Denmark will be affiliated with the Centre. When fully operational, the centre will employ and engage more than 100 people.
