Statistical analysis of the CASP Barents Shelf provenance dataset indicates that sediment maturity prior to burial diagenesis exerts by far the most significant control on resultant sandstone reservoir quality. This project tests this conclusion and helps improve models for reservoir presence and quality by investigating the relative importance of various source to sink factors on sediment maturity in the Late Triassic - Middle Jurassic Realgrunnen Subgroup and Late Palaeozoic successions of the Barents Shelf. This will be achieved through a combined field and analytical programme of research.
- An investigation of the provenance of the Realgrunnen Subgroup to help define the number and scale of systems delivering sand onto the Shelf.
- A study of the relative importance of the effects of source to sink factors and recurrent Late Palaeozoic unconformity development on sandstone reservoir properties.
- A review of the crystalline basement to improve terrane models and the framework for the interpretation of sandstone provenance studies.
- A source rock study of the Hopen and Edgeøya well materials so that the petroleum potential of the northern Barents Shelf may be assessed.
- A refinement of Triassic sand dispersal patterns by further field and sedimentary provenance investigations.
Project length: 24 months from December 2017
