ARCEx partner UiT The Arctic University of Norway in Tromsø is hiring a PhD fellow in Petroleum Geology; trap and seal analysis of the northern Barents Shelf. The 3-year fellowship will be affiliated to work package 1/2 in ARCEx, and the candidate will be part of an interdisciplinary research group (that includes structural geologists, sedimentologists, geophysicists, and modellers) from both national collaborators and industry partners.
The position’s field of research:
Although the majority of exploration wells in the Barents Sea has encountered hydrocarbons, only two fields, the Snøhvit (gas) and the Goliat (oil) fields, are currently in production. The geological evolution of the area, including previous deep burial and subsequent exhumation, has contributed to the leakage of hydrocarbons from many traps. Understanding the timing of hydrocarbon generation and migration, trap formation and regional cap rock properties, as well as the exhumation history of the area is crucial to succeed in reducing the exploration risk in the Barents Sea. This PhD project focuses on top-seal characterization and cap rock integrity with an overarching goal of understanding geological risk factors that have influenced seal integrity in a spatial-temporal framework. Important tasks in the project are to systematically investigate (geophysically,sedimentologically, and/or petrophysically) and compare selected case studies from the Barents Sea (e.g., the greater Hoop area) in order to understand seal properties and the regional distribution of stratigraphic units with seal capacity. Fault systems, and other possible cap-rock bypass systems, should also be investigated.
In order to achieve these objectives, the candidate will perform seismic facies analysis, analyse pressure and fracture data, as well as analyse core and geophysical log data. Seismic data will aid in establishing the structural framework in the selected cases, but also aid in the development of local- and regional-scale cap-rock distribution maps, as well as sequencestratigraphic models. If feasible, fieldwork and investigation of onshore analogues and drill cores on Svalbard will be considered.
The candidate will be provided with relevant seismic and well data. The candidate will be supervised by a committee consisting of Sten-Andreas Grundvåg (UiT), Kim Senger (UNIS) and Jan Inge Faleide (UiO), as well as an industry co-supervisor (yet to be identified).
Application deadline: 22 April 2018.
