Equinor, Vår Energi and Petoro will make investments simply over NOK 4 billion to develop the Isflak discovery— the primary discover to be tied again to the Johan Castberg discipline in Norway’s Barents Sea. The choice comes eight months after Johan Castberg got here onstream and continues the operator’s technique to construct the sector right into a long-term manufacturing hub for the area.

The brand new subsea growth, estimated to carry 46 MMbbl of recoverable oil, is predicted to start out up as early as This fall 2028. Equinor stated the fast-track schedule is feasible as a result of the Isflak reservoir sits inside the similar license (PL 532) and is just like present Johan Castberg discoveries, enabling reuse of standardized tools and nicely designs.
“Johan Castberg has been developed as a future hub within the space. Isflak is the primary of a number of discoveries now being matured for extra volumes,” stated Trond Bokn, Equinor’s SVP for undertaking growth. “This may have ripple results for Norwegian suppliers.”
Johan Castberg, which started manufacturing in March, is at the moment delivering round 220,000 bpd. Estimated recoverable volumes for the hub stand between 450–650 MMbbl, however Equinor sees important upside—doubtlessly 250–550 MMbbl from new wells and satellite tv for pc tiebacks. Six new improved oil restoration wells are already deliberate, and the partnership is evaluating how rapidly this 12 months’s Drivis Tubåen discovery might be introduced on-line.
Equinor stated the undertaking displays an evolving Norwegian continental shelf, the place most future developments might be smaller finds quickly tied again to present infrastructure to cut back prices, emissions and prolong discipline life.
The Isflak idea consists of two wells in a brand new subsea template tied again by way of pipelines and umbilicals to present Johan Castberg services. All infrastructure will stay inside the present license space. Equinor has utilized to the Ministry of Vitality for affirmation of impression evaluation obligations and an exemption from submitting a full plan for growth and operation.
