The Norwegian CO2 Storage Atlas

The CO2 storage atlas of the Norwegian part of the North Sea and Norwegian Sea has been prepared by the Norwegian Petroleum Directorate at the request of the Ministry of Petroleum and Energy. The main objectives have been to identify the safe and effective areas for long-term storage of CO2 and to avoid possible negative interference with ongoing and future petroleum activity. 27 geological formations have been individually assessed, and grouped into saline aquifers. The assessed aquifers have been ranked according to guidelines which have been developed for this study. The evaluation of geological volumes suitable for injecting and storing CO2 can be viewed as a step-wise approximation as shown in the maturation pyramid. A modeling study will be presented to understand the timing and extent of long distance CO2 migration
