Det norske has a solid resource basis. The discovery of the Johan Sverdrup field in 2011, the discovery of the additional Geitungen structure and several successful appraisal wells in 2012 have trebled the company’s resources. The most important contingent resources amount to between 308 and 487 million barrels of recoverable oil equivalents. These originate from seven discoveries, of which around 80 percent originate from the Johan Sverdrup field. There is significant uncertainty attached to estimation of recoverable volumes with regard to reservoir models, ownership interests, investments and cyclical fluctuations.

The drilling of future wells on Johan Sverdrup will help to reduce this uncertainty. The net total proven reserves that can be recovered from Det norske’s portfolio with a 50 percent probability are estimated to be 65.3 million barrels of oil equivalents. Most of these, around 80 percent, come from the Ivar Aasen field.
