UK divided over 8.7 billion pound oil field

The licensing process for the 8.7 billion pound Rosebank oil field has split the cabinet in 2 within the UK government in the midst of an oil shock. Located 80 miles northwest of the Shetland Islands and representing the country's largest undeveloped field, the project is owned 80% by the Adura partnership (Equinor and Shell) and 20% by Ithaca Energy. In the government led by Prime Minister Andy Burnham, Chancellor John Healey and Business Secretary Jonathan Reynolds want the field approved on the grounds of jobs and tax revenues, while Energy Secretary Miatta Fahnbulleh and Foreign Secretary Ed Miliband oppose the project due to climate commitments.

Why did the Rosebank project split the UK cabinet?

Planned to meet approximately 1/10 of the UK's expected oil production by pumping approximately 69,000 barrels of oil per day, Rosebank holds reserves of 500 million barrels of oil equivalent, with approximately 90% being oil according to Rystad Energy calculations. Ithaca Energy estimates the volume of recoverable oil across 2 development phases at approximately 300 million barrels. While the production vessel has been waiting at the field since June, environmental groups state that production at the field will lead to over 200 million tons of carbon dioxide emissions and generate approximately 7 times more emissions than the Jackdaw field approved on October 21. The Scottish High Court also overturned the field's initial approvals in January 2025 on the grounds that consumption emissions were not taken into account.

What is the state of North Sea production and oil prices?

At a time when reserves in the North Sea are depleting rapidly, the UK's proven and probable reserves dropped by 0.4 billion barrels to 2.5 billion barrels of oil equivalent at the end of 2025, while not a single exploration well was drilled on the continental shelf throughout 2025. While the Jackdaw field is expected to come online within weeks to supply an approximate 6% share of North Sea gas production, Chancellor Healey announced an initial payment of 2 billion pounds for the new Energy Wealth Fund, into which future oil and gas revenues will be transferred.

While Norway's 2.3 trillion dollar sovereign wealth fund model is cited as an example, Treasury analyses reveal that had approximately 200 billion pounds in revenue generated since the 1980s been invested, the fund could have reached the 1 trillion pound level. The Norwegian fund managed by Norges Bank, after posting a record profit of 184.3 billion dollars in the 1st half of 2026, reported a loss of 29.7 billion dollars in the 3rd quarter due to rising borrowing costs.
