UK weighs oil production price floor as CNOOC North Sea earnings fall 90%
Bloomberg reports London may use a contract-for-difference to subsidise North Sea output as operator finances deteriorate sharply.
The UK government is exploring a price floor subsidy for North Sea oil production, structured as a contract for difference, Bloomberg has reported — a mechanism that would guarantee producers a minimum revenue per barrel and require the state to pay the gap when ICE Brent crude front-month trades below the strike.2
The timing is awkward for a government that blocked North Sea expansion less than a month earlier. Energy Secretary Ed Miliband vetoed a Treasury plan, reported by The Telegraph on Thursday (2026-06-25), to boost North Sea drilling as a way to fund part of Britain's increased defence spending, siding with Labour's policy of issuing no new drilling permits. A subsidy that keeps existing production alive would mark a sharp departure in both direction and political logic.4
CNOOC Petroleum Europe Limited's 2025 results, published on Wednesday (2026-07-02) by Energy Voice, illustrate what the government would be trying to arrest. The North Sea arm of the Chinese state-controlled operator reported a 90% drop in earnings, with income from operations before tax falling to $37 million from $379 million in 2024. Panmure Liberum resources director Ashley Kelty told Energy Voice the accounts make for "pretty gloomy reading."5
Production decline drove much of the damage. CPEL's net share of output fell to 18,146 barrels of oil equivalent per day in 2025, down from 24,259 boe/d in 2024, a drop of more than 25%. The Buzzard field, where CNOOC holds a 43.2% stake, was the biggest contributor to the slide, with the company's share of output falling nearly 40% to 10,061 boe/d from 16,472 boe/d.5
Decommissioning liabilities are building faster than profits can absorb them. CPEL's total decommissioning provision rose to just over $1.2 billion at the end of 2025, up from $971 million in 2024, an increase of more than 24%. A provision of that scale sitting against a pre-tax profit of $37 million suggests the company's North Sea position is being managed for exit rather than growth.5
CNOOC has not announced a withdrawal, but Kelty's reading of the accounts implies it may follow other major operators that have already shrunk their North Sea exposure. The company holds interests in Scott, Telford, Rochelle and Golden Eagle, none of which are growing on current output trends.5
A contract-for-difference on oil prices would mirror the mechanism the UK already uses for offshore wind, with the Treasury paying producers when ICE Brent crude front-month falls below the agreed floor and recouping the upside above a strike price ceiling. At Thursday's (2026-07-24) level of $100.38 per barrel, the subsidy would be dormant. But the UK's Energy Profits Levy already captures 78% of North Sea profits, meaning any future floor payment would involve a circular fiscal transfer between the government's own accounts.2,4
The political case for the subsidy rests on energy security concerns sharpened by the Gulf disruption. The Guardian reported in May (2026) that Britain, facing an energy crisis worsened by the blockade of Gulf shipping lanes, had been left exposed by years of inadequate preparation. Conservative leader Kemi Badenoch, commenting on a University of Aberdeen study published on Wednesday (2026-06-03), called Labour's North Sea ban "utter madness" and cited the research's conclusion that prioritising domestic oil production would be "economically, environmentally, and strategically beneficial."3,1
A CFD floor would not reverse the basin's geological decline. UK oil and gas production has been falling for two decades as mature fields deplete. What it would change is investment timing — pushing back the point at which operators shut in marginal wells and crystallise decommissioning liabilities that the state would ultimately share.2
Analysts cited in the Telegraph report suggested political turmoil could prompt UK leadership to reassess North Sea resource use for energy security purposes. The fiscal obstacle is the same one that killed the Treasury's drilling-expansion plan: any CFD with contingent liabilities would require upfront scoring by the government's fiscal watchdog, a commitment Miliband's veto in June (2026) showed the cabinet is reluctant to make.4
Whether the Treasury signals a budget provision for North Sea CFDs in its autumn fiscal statement will determine how seriously producers should take the Bloomberg report. Until then, operators will keep reading accounts like CNOOC's and drawing their own conclusions about the basin's remaining commercial life.5
