Task 9 - Structural de-risking aims to reduce risk related to injecting and storing CO2 and develop techniques to address fault sealing and integrity. The research group at the Department of Geosciences, University in Oslo, are currently involved in mapping and modelling of faults and migration pathways on the Horda Platform and Stord Basin in the North Sea: the future Northern Light storage site and a potential future storage cluster region.
- Systematic mapping of aquifer and seal pairs to highlight additional storage volumes related to future satellite storage sites in the region.
- Refining of aquifer models for the area and improving understanding of along fault flow and fault reactivation. This work has aided CO2 plume modelling uncertainty and impacted on location selection for the initial Smeaheia well at the Northern Lights site.
- Improving geological models for the topseal /caprock succession for storage de-risking and provision of basis for further geomechanical work.
- Addressing challenges related to pressure depletion prior to injection by adding understanding of cross-fault pressure communication from the Troll oil and gas field.
