The Danish Hydrocarbon Research and Technology Centre (DHRTC), Technical University of Denmark (DTU), invites applicants for a PhD position on chemical characterization and environmental impact assessment of produced water for the academic session 2021-2022.
This PhD position is part of a larger project portfolio relating to the management of produced water from Danish North Sea Chalk reservoirs.
|Scholarship Sponsor||Technical University of Denmark|
|Scholarships level||PhD Scholarship|
|Fellowship Period||Three years|
|Study area||Environmental Science|
|Opening date||February 24, 2021|
|Closing date||March 15, 2021|
The Danish Underground Consortium and DTU established the Danish Hydrocarbon Research and Technology Centre (DHRTC) in 2014 as part of a national strategy for energy. The research Centre is an ambitious, targeted effort to improve hydrocarbons’ recovery from the Danish North Sea sector. When crude oil is produced, large amounts of water is produced along with the petroleum fluid. This water is contaminated from contact with crude oil and production additives.
DHRTC has initiated a research program focusing on solutions to the ambition of zero harmful discharge through improved produced water management. The solutions developed in this program will target industrial and environmental challenges with paid water management and be more generally applicable to water treatment technology, geothermal energy and subsurface storage technologies.
The deadline for applications is March 15, 2021
Approval and Enrolment
The PhD degree scholarships are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the available planning of the PhD study programme, please see the DTU PhD Guide.

The project aims at developing an improved assessment tool for identifying environmental impact from water production in connection with offshore oil production. The project will target the ecological assessment of dissolved and dispersed petroleum constituents in produced water, which is separated from the oil stream and are discharged to the sea.
In many cases, the volume of produced water (PW) exceeds the produced oil volume. This water contains varying amounts of petroleum constituents and remnants of production chemicals, many of which fall into chemical classes that are of potential environmental concern and further treatment of produced water (e.g. surfactants, phenols, poly-aromatics, metals and oil droplets in water (OIW)).
An improved ecological impact assessment relies on monitoring the actual concentrations of pollutants in the PW to compare with current evaluation methods, threshold values. By combining detailed analysis with additional information from REACH classifications and toxicology studies of produced water from oilfields, the project will define a more detailed assessment tool to compare with current industry practice.
This PhD project will take off-set a collaborative effort on detailed characterization of specific target compounds and compound classes by analytical chemistry techniques. The goal is to understand the type of constituents present in the water phase in produced water from oil fields. The main focus is on surface-active and polar compounds, including production chemicals and additives, that are most active at interfaces and can significantly partition into the water phase.
These are particularly challenging for disposal and discharge to the marine environment. Measurements of dispersed non-polar hydrocarbon oil components will be benchmarked by the current OSPAR reference method for OIW determination. The candidate will work closely with the research team carrying out detailed chemical analysis of produced water samples, as well as with industry experts, to generate the data necessary for the environmental impact analysis.
The project will involve close collaboration with partner laboratories at DTU Environment and the produced water monitoring projects ongoing at DHRTC.
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.
Furthermore, you must have
