As BP Leaves the North Sea, These Independents Are Buying In

Three UK North Sea energy companies are gaining attention as BP exits the region: Harbour Energy, EnQuest, and Ithaca Energy. Harbour Energy, which produced a record 509,000 barrels of oil equivalent per day in the first half of 2026, recently completed a major acquisition of Wintershall Dea's upstream portfolio outside the UK. This acquisition brought Harbour more than double the company's previous output and doubled its 2026 production guidance to 490,000-500,000 boe/d.

Harbour's growth pipeline is also located outside the UK, with the SESA LNG project in Argentina and potential developments in Mexico. EnQuest, a leading UK North Sea producer, is expanding into Southeast Asia by acquiring four offshore Malaysian production-sharing contracts from Petronas Carigali and E&P Malaysia Venture for up to $833 million.

This deal will increase EnQuest's production to about 100,000 boe/d and lift reserves by 85% to roughly 300 million boe. Ithaca Energy, formed by the 2024 combination of Eni's UK assets with Ithaca, is also investing outside the UK. It recently acquired Suncor's offshore Newfoundland stakes for $860 million, including interests in Terra Nova and White Rose fields.

These investments are expected to produce about 30,000 boe/d from 2027 to 2031. The future of these companies will depend on the outcome of pending legal challenges and government approval for the Rosebank project.
