BP announced on 31 July 2026 that it is putting its North Sea oil and gas business up for sale. The move is part of a broader review BP has been conducting to decide which parts of its business to keep and which to sell off.

BP has already been shrinking its presence in the North Sea. In December 2025, it sold the Culzean gas field to a company called NEO Next. The assets that remain include the Seagull oil and gas field and the Alligin field, which recently received approval from the UK's Oil and Gas Authority to be developed. BP's most recent financial results, published on 28 April 2026, show that its gas and low carbon energy division made a profit of $1.1 billion in the first quarter of 2026, compared to a loss of $2.2 billion in the same period a year earlier.

The sale process is happening under new leadership. Meg O'Neill took over as BP's CEO in July 2026, stepping into a review that was already underway. BP's press release, dated 31 July 2026 and titled "bp to market North Sea business," makes clear that this is the start of a sales process, not a finished deal.

A key factor hanging over any sale is the cost of carbon emissions. BP's 2025 Annual Report, published on 6 March 2026, assumes that UK carbon costs will be £65 per tonne of CO2 in 2026 and will rise to £243 per tonne by 2050. Think of carbon costs as a tax on pollution: the more a facility emits, the more it pays. For old oil and gas fields in the North Sea, those rising costs matter a lot, because whoever buys them will eventually have to pay to shut them down safely — a process called decommissioning.

BP's activities extend well beyond the North Sea. In the first quarter of 2026, about 49 million barrels of crude oil were shipped from the Caspian region through the Turkish port of Ceyhan, loaded onto 65 tankers. BP also published a trading statement on 14 April 2026, two weeks ahead of its full financial results.

The broader context here is that BP is reshaping its business under a brand-new CEO, and the North Sea sale is part of that. O'Neill has not yet laid out a detailed public strategy beyond the portfolio review, but any buyer looking at BP's North Sea assets will have to weigh the money those fields can still earn against the rising costs of carbon taxes and eventual shutdown. The jump from £65 to £243 per tonne of CO2 means operating costs could climb sharply over the remaining life of these fields, especially the ones that produce a lot of gas.

For anyone watching the markets, the big questions are simple: who will buy, and for how much? The Culzean sale to NEO Next gives a recent example of a North Sea deal, though the price was not made public. Whether the remaining assets attract similar interest will depend on how buyers weigh decommissioning costs, carbon taxes, and the difficulty of running older fields. BP's announcement says it is a "process to market," which means no buyer has been found and there is no timeline for completion.

The sale also comes at a moment when BP's gas business is bouncing back financially. The shift from a $2.2 billion loss to a $1.1 billion profit in Q1 2026 suggests that energy prices and operations have improved, which could give BP more leverage in negotiations — or reduce the pressure to accept a low offer. Either way, the sales process is only just beginning.
