Hydrocarbon column height controls in Jurassic reservoirs on the Nordland Ridge
This Master's project was designed for Natalie Juliussen who started her Master's program in Earth Sciences, UiB, in the fall semester 2023. The Master's project is given by the research group Geodynamics and basin studies.

Project description
A previous MSC thesis at the UiB (Osen, 2018) concluded that a relationship between clay in fault zones and their sealing capacities in Jurassic traps along the Nordland Ridge. Later investigations at other parts of the NCS has shown that such relationships are not present everywhere. This thesis will look into the across-fault sealing properties of faults in the area and evaluate the causes for fault sealing and to what extent they are unique for the Nordland ridge. Possible explanations include continuous clay smears and thickness of smeared clay layers, stratigraphic inhomogeneities, fault strike and throw relative to the stress field.
The thesis work will include seismic interpretation and model building in Petrel, well log analyses, inspection of pore pressure data for fluid contact identification and basic statistical evaluation of the observations. General knowledge of sedimentology will be used to evaluate the consequences of lithology changes within the individual reservoir zones.
