We have opened a new PhD position in basin evolution, paleogeography and source to sink analysis of the upper Paleozoic succession in the Norwegian North Sea. This PhD will be funded by UiS the three first years and the last year by PaBas. The candidate is expected to start in the beginning of next year (2020).

New Msc Students
Two master students have now joined our team; Sanja Jovanovic Lazarevic and David Rodriguez. They will work with tectonostratigraphic evolution of the Southern Viking Graben and Sørvestlandet High, focusing in the upper Paleozoic.

Progress
We just finished sampling cores, cuttings and oils at Weatherford and are currently obtaining sediment samples from cores and cuttings at NPD. In early May, we also had a field trip to Aberdeen to sample oils and cuttings from wells in the J-block and the Kessog Field northwest of the Embla Field.
7 wells will be sampled for facies variation in the Upper Jurassic at NPD. 3 wells were sampled at Weatherford and 4 wells in Aberdeen.
14 wells with cores in the Rotligendes Gp will be sampled...

Evidences for Pre-Jurassic oils in the North Sea
Embla field producing oil from Permian and Devonian reservoirs:
Reservoir sand with GC trace of produced oil:
Core plugs of Embla rhyolites with GC of biodegraded oil, and re-generated waxy oil from the biodegraded oil. The latter was trapped in fluid inclusions roughly 200Ma ago, ie. Pre-Jurassic:
Typical Kimmeridge oil with low wax, concave n-alkane profile, absence of gammacerane whereas Paleozoic sourced oils are different:
