Andreas Hagset started as a new PhD student at UiT The Arctic University of Norway on 1 September 2018. He will be associated with WP1/2 in ARCEx. Hagset is funded by DEA Norge AS and will be working during the next three years with his PhD project titled “Organic geochemical assessment and mapping of potential oil-prone Lower Cretaceous source rocks in the Vøring and Western Barents Sea Basins, Norway“.

I have done both my Bachelor’s and Master’s degree here at the Department of Geosciences at UiT The Arctic University of Norway, and I am very glad for the opportunity to come back to do a PhD project. I am also glad to see so many familiar faces, and I look forward to good discussions and collaboration.

I have a fundamental research interest within sequence stratigraphy and development of petroleum systems. This PhD project is therefore very exciting, as it includes the tectonostratigraphic development of Lower Cretaceous stratigraphy and source rocks in both the Barents and the mid-Norwegian continental shelf. I look forward to gain new knowledge and work with our industry partner DEA Norge throughout this project.

I wrote my Master thesis at ARCEx. The thesis combined seismic sequence stratigraphy with well data and geostatistics. The title of the thesis was «Seismic attributes, well correlation and geostatistical analysis for sequence variability prediction in the Sleipner area”. The objectives of the thesis was to identify and interpret Cenozoic seismic sequences, and classify them according to reflection configuration using high quality seismic data and attributes. In addition, utilization of well data and geostatistical methods made it possible to interpolate well logs some distance away from the well locations in each sequence. Based on the results from the geostatistical operation, I was able to study well-log parameters laterally within each sequences. These results where supplemented with a discussion of the Cenozoic depositional environment in the Southern Viking Graben, Sleipner area.

My PhD research will focus on basin development and source rock characteristics of the Lower Cretaceous intervals. The study area will include the Norwegian continental margin from the Møre Basin in the South, to the SW Barents Shelf in the North. The overall objective for this project will be to investigate the Lower Cretaceous basins with the aim to interpret the spatial and lateral variations of potential source rocks, both on a regional and sub-basin scale.

The project will take a more holistic approach to improve the understanding of possible Lower Cretaceous source rocks. This will include a regional tectonostratigraphic approach, were the objective is to identify the depositional environments and the controlling factors under accumulation of Lower Cretaceous stratigraphy. Regional well ties and geochemical databases will also help determine the lateral extent and magnitude of the stratigraphy. This will allow for improved assessment of hydrocarbon potential in the study area.
