Harbour Energy Enters U.S. Gulf with $3.2B LLOG-Acquisition

London-listed Harbour Energy has officially completed its $3.2 billion acquisition of U.S.-based LLOG Exploration Company, marking the UK firm’s strategic entry into the deepwater U.S. Gulf of Mexico. The deal, finalized in December 2025, comprised $2.7 billion in cash and $500 million in Harbour ordinary shares. This move establishes a new core business unit for Harbour alongside its existing operations in Norway, the UK, Argentina, and Mexico, significantly expanding its global footprint. The acquisition provides Harbour with a fully operated, oil-weighted portfolio in one of the world’s most prolific offshore oil and Gas basins. LLOG’s assets averaged production of 36,000 barrels of oil equivalent per day (boepd) in 2025, bolstered by strong performance at the Who Dat and Buckskin hubs, as well as the October 2025 start-up of the Leon-Castille field. Harbour Energy expects production from these assets to grow to 65,000–70,000 boepd by 2028. The deal adds high-margin, long-life assets and a deep inventory of high-return drilling opportunities, enhancing Harbour’s overall production profile and long-term growth potential
