Equinor announced progress on the future Phase 4 of the Johan Sverdrup field after confirming new oil volumes in the Tonjer and Geitungen area, located in the Norwegian North Sea.
The discoveries will enable the development of a new subsea project connected to the existing infrastructure of Norway’s largest oil field, with the aim of maintaining production over the coming decades.
The results come from appraisal wells recently completed in the area. According to the company, the new resources will serve as the basis for a new development stage that could come on stream in 2029, once the technical studies and the corresponding investment decisions have been completed.
New resources to sustain future production
Preliminary estimates place the recoverable resources in the Tonjer and Geitungen reservoirs at between 20 and 30 million barrels of oil equivalent. Equinor indicated that additional subsurface analyses will refine these figures in the coming months.
The project envisages developing the Tonjer East, Tonjer West, and Geitungen discoveries through subsea installations connected to Johan Sverdrup. This strategy leverages the infrastructure already in operation to reduce costs, speed up execution timelines, and minimize emissions associated with the development.
Kjetil Hove, Equinor’s Executive Vice President for Development and Production Norway, noted that these new volumes are profitable and will help strengthen production and value creation for one of the most important assets on the Norwegian continental shelf.
Existing infrastructure to accelerate development
Johan Sverdrup began operations in 2019 and has become one of the main drivers of Norway’s oil production.
The field stands out for its low operating costs and emissions intensity below the industry average thanks to its onshore power supply system.
According to Equinor, developing new resources near existing facilities is part of a strategy aimed at maximizing hydrocarbon recovery and extending the service life of assets already developed.
Strategic production for Norway and Europe
The company believes that the future Phase 4 will help maintain Johan Sverdrup’s role as one of Europe’s leading oil suppliers. In addition to sustaining production, the project aims to generate additional value through faster and more efficient subsea developments.
The partners in the Johan Sverdrup field are Equinor, with a 42.62% stake; Aker BP, with 31.57%; Petoro, with 17.36%; and TotalEnergies, with 8.44%. The project is part of the portfolio of subsea developments that Equinor aims to accelerate over the coming years.
