Norwegian CO2 Storage Atlas

To get a good overview of where and how much CO2 that can be stored in the Norwegian North Sea, a team in the Norwegian Petroleum Directorate has evaluated all relevant data in this area in order to identify potential storage sites. The Norwegian Minister of Petroleum and Energy launched the CO2Storage Atlas for the Norwegian North Sea, December 13th 2011. The experience and results from the on-going CO2 storage projects at the Sleipner Vest and Snřhvit Fields offshore Norway have been valuable in our work, together with data from more then 40 years of petroleum activity. NPD has access to all data collected in the petroleum activity. The work presented in this Atlas includes evaluation of 21 geological formations (saline aquifers) and 12 abandoned hydrocarbon fields. 62 producing oil and gas fields have been evaluated for storage potential and for enhanced recovery. Through a systematic evaluation process, detailed characterization forms were established. The criteria evaluated are covering critical factors for both reservoir properties and for sealing qualities that has to be met before it can be defined as a CO2 storage site. A differentiation related to the maturity of storage sites has been established
