BAKU, Azerbaijan, June 15. New oil volumes
confirmed in the Johan Sverdrup area are paving the way for the
next development stage of Norway’s largest producing oil field, as
Equinor and its partners move forward with plans for Johan Sverdrup
Phase 4.


Equinor said in a message on its website that recent appraisal
drilling in the area has identified additional recoverable
resources, strengthening the long-term production outlook for the
field and reinforcing its role in supporting Europe’s energy
supply.


The newly confirmed volumes originate from the Tonjer West,
Tonjer East and Geitungen discoveries and are expected to be
developed through a subsea tie-back solution linked to existing
Johan Sverdrup infrastructure. According to Equinor, the approach
is designed to maximize value creation while utilizing established
facilities.


“New volumes in the Johan Sverdrup area provide the basis for
Johan Sverdrup phase 4,” the company said, adding that the project
is intended to help sustain production levels and extend the value
generated by the field.


Located in the northern section of the Geitungen terrace within
the Johan Sverdrup area, Tonjer had previously yielded oil
discoveries, although uncertainty remained regarding the scale of
recoverable resources. Following the completion of two appraisal
wells and an additional sidetrack, the partnership now says it has
obtained a significantly clearer understanding of the resource
base.


Preliminary estimates indicate that combined recoverable
resources from Tonjer and Geitungen range between 20 million and 30
million barrels of oil equivalent. Additional subsurface analysis
is expected to refine these estimates further.


The project is currently progressing toward an investment
decision, with a potential production start-up targeted for 2029.
The development aligns with Equinor’s broader strategy to
accelerate execution across its extensive subsea project
portfolio.


According to the company, the objective is to strengthen value
creation from mature producing assets by shortening development
timelines and increasing the number of subsea projects connected to
existing offshore infrastructure.







The initiative also reflects the joint strategy of the Johan
Sverdrup partnership, which includes Equinor (42.62%), Aker BP
(31.57%), Petoro (17.36%), and TotalEnergies (8.44%).


Located on the Norwegian continental shelf, Johan Sverdrup
remains one of Europe’s key energy assets and currently accounts
for around one-third of Norway’s total oil production.


The field, which contains estimated reserves of 2.7 billion
barrels of oil equivalent, reached a major milestone with Phase One
beginning production in October 2019 and Phase Two coming on stream
in December 2022.


At plateau levels, Johan Sverdrup is capable of producing up to
755,000 barrels of oil per day, making it one of Europe’s most
significant offshore production hubs.


Equinor also highlighted the field’s environmental profile,
noting that Johan Sverdrup records carbon dioxide emissions that
are 80–90% lower than the global average for oil fields, supported
by electrification powered from shore.


Equinor remains the largest oil producer on the Norwegian
continental shelf and reported equity oil and gas production of
approximately 2.137 million barrels of oil equivalent per day in
2025.
