Assessment of the Triassic and Jurassic hydrocarbon reservoir intervals in the SW Barents Sea
Main content
The project aims to add to the current understanding of the Early to Middle Mesozoic reservoir intervals in the Norwegian Barents Sea, primarily in the southwest. Because of the large difference in appearance of the different intervals, different methodologies and research topics are employed.
The Kobbe and Snadd formations consist of prograding shelf-edge and shoreline systems. By studying in detail the shapes of seismically defined clinoforms a quantitative assessment of their variability and lithology will be performed. Careful investigations might also reveal depositional trends that can be linked back to rates of delta progradation and delta lobe switching. Differential subsidence across the basin will also be recorded in the accumulated heights of the clinoform successions and they can thus potentially reveal information about areas of accommodation and the basin configuration at the inception of discrete clinoforms.
The shallow marine Stø Formation is the most important reservoir interval in the Barents Sea. New discoveries in the formation in the area of Johan Castberg and the Hoop Fault Complex have extended the interest in the reservoir quality and architecture of this formation northwards from the Hammerfest Basin. The project aims to improve the facies, sequence stratigraphic and paleogeographic models for the formation in the Hoop Fault Complex area through analysis of core material, potentially also integrated with seismic data.
This project is funded by Tullow Oil Plc Norway.
