Contact metamorphism around thin intrusions in Central Isfjorden: implications for reservoir quality and fluid migration, RiS ID 10408

The proposed target unit for CO2 storage in Central Isfjorden comprises a naturally fractured heterolithic sandstone-siltstone sequence interbedded with shale layers. Igneous intrusions have been identified in the target aquifer and are mapped. These igneous intrusions and their contact aureole is something that alter the reservoir properties. The aim of the study is to investigate the petrography of the contact aureole and to do fracture mapping in order to contribute to the understanding of the reservoir quality.
