Aker BP ASA has announced an increase in its ownership interest in the Johan Sverdrup field following the completion of a formal redetermination process conducted under the field’s unit agreement. The revised ownership share rises to 31.7163 percent, up from 31.5733 percent, reflecting updated technical assessments and production data.
The redetermination process, initiated in January 2025, involved a comprehensive review of reservoir performance, production history and field development data. An independent expert assessment formed part of the process, resulting in adjusted ownership allocations among the field’s partners. Such reviews are a standard mechanism used in large unitized fields to ensure that participating companies hold interests that accurately reflect the value of the resources attributable to their respective license areas.
As a result of the revised ownership structure, historical investments and production volumes associated with the field will be redistributed among the partners. For Aker BP, the adjustment is expected to deliver additional production volumes equivalent to approximately 2.2 million barrels of oil equivalent over the next two years.
The company also noted that it will make a payment of around NOK 300 million before tax to account for the reallocation of historical investments linked to the field. The financial and operational effects of the redetermination will be reflected in Aker BP’s accounts beginning in the third quarter of 2026.
The ownership adjustment does not affect day-to-day operations at Johan Sverdrup, which continues to rank among the most productive and efficient oil fields on the Norwegian continental shelf. The field remains a cornerstone asset for Norway’s petroleum industry and continues to deliver strong production performance.
Operated by Equinor, Johan Sverdrup is one of the largest oil developments in Norway’s history and plays a vital role in supplying energy to international markets. The field has consistently demonstrated high recovery rates, low production costs and reduced emissions intensity compared with many global offshore developments.
Aker BP remains a significant partner in the project and views the revised ownership interest as further strengthening its position in one of the most important producing assets in its portfolio. Aker BP is a leading exploration and production company focused on oil and gas activities on the Norwegian continental shelf. Headquartered in Fornebu, Norway, the company operates several major field centres and maintains interests in some of the region’s most strategically important energy developments.
