Equinor and its partners are proceeding with plans for a fourth development phase at the Johan Sverdrup field following new oil discoveries confirmed by recent appraisal wells in the area.
The Tonjer west and east discoveries, along with Geitungen, will underpin the next stage of development for Norway’s largest oil-producing field, according to Equinor
Joint preliminary resource estimates for Tonjer and Geitungen are between 20 and 30 million barrels of oil equivalent. Recent drilling in the northern part of the Geitungen terrace included two appraisal wells and a sidetrack, providing more clarity on the resource base after earlier uncertainty. Equinor said further analysis of subsurface data will inform more precise resource estimates.
The Norwegian oil and gas company stated that phase four will involve a subsea development, with new resources tied back to the existing Johan Sverdrup infrastructure. The project aims to help maintain production and value creation from the field, while also supporting Europe’s energy security. Equinor Norway development and production executive vice-president Kjetil Hove said: “These are important and profitable volumes for Johan Sverdrup.
