Tectonostratigraphic evolution and reservoir distribution of the Lower to Middle Jurassic strata of the Nordland Ridge

Project description
The Nordand Ridge is an important structural element which records the early stages of continental breakup between Norway and Greenland. In addition, the area continues to be an important area for hydrocarbon exploration with recent discoveries in Cretaceous strata (Cape Vulture and Black Vulture), and remaining untested Jurassic structures close to existing infrastructure.

Compared to the North Sea and the Barents Sea, the Norwegian Sea has received limited academic interest and studies have either focused on specific stratigraphic intervals or areas. The Lower to Middle Jurassic stratigraphic intervals are, as they are in other parts of the Norwegian Continental Shelf, the most important for hydrocarbon exploration and production, but the stratigraphic development of the succession has so far not been the subject of detailed studies.

Within this succession there are important undocumented stratigraphic breaks that reveal a complex tectonic evolution prior to continental break up between Norway and Greenland. This evolution has large impact on the distribituion of reservoir rocks and their preservation, and is consequently very important for hydrocarbon exploration in the area. Knowledge about these stratigraphic breaks can also be used to constrain the larger-scale geodynamic evolution of the basin.

Petrolia Noco is a Bergen based exploration and production company with interests on the Nordland Ridge north of the Norne field. The student will work closely with our young and dynamic team of geologists and geophysicists investigating regional datasets and 3D seismic data in order to understand the tectonostratigraphic evolution of this important reservoir interval and Norwegian-Greenland margin.

The project will be based out of the University of Bergen, but with regular visits to Petrolia Noco offices. Here, the student will be introduced to the project and relevant data. The student will work mainly with the industry-standard interpretation software such as Petrel but other relevant software tools will also be considered. Study of relevant core intervals at the Norwegian Petroleum Directorate core store in Stavanger should be performed.

Proposed course plan during the master's degree (60 ECTS):
GEOV372 / Integrert tolkning av seismikk og geofysiske data (5 ECTS)
GEOV260 / Petroleumsgeologi (10 ECTS)
GEOV272 / Seismisk tolkning (10 ECTS)
GEOV360 – Vidaregåande klastisk sedimentologi (10 ECTS)
GEOV362 – Integrert feltkurs i tektonikk og sedimentologi (5 ECTS)
GEOV352 – Reservoargeologisk feltkurs (5 ECTS)
GEOV361 / Sekvensstratigrafi (10 ECTS)
GEOV300 / Utvalgte emner i geovitenskap (5 ECTS)

Other relevant courses if the student already has taken some of the courses above:
GEOV302 / Dataanalyse i geovitskap (10 ECTS)
GEOV251 / Videregåande strukturgeologi (10 ECTS)

The student must have a basic understanding of topics relevant for sedimentology and structural geology, and preferably some proficiency in seismic interpretation and vector drawing software.
