What LLOG Exploration Company does
LLOG Exploration Company is a privately-held deepwater offshore oil and gas exploration and production company headquartered in Covington, Louisiana, founded in 1977 and operating in the U.S. Gulf of Mexico. The company produces hydrocarbons from ultra-deepwater fields at approximately 6,400 feet water depth, with current production of approximately 36,000 barrels of oil equivalent per day and 271 million barrels of 2P reserves. Its core asset base includes the Salamanca Floating Production Unit, which has a capacity of 60,000 barrels of oil per day and 40 million cubic feet of natural gas per day and produces from the Leon and Castille fields, alongside a broader deepwater portfolio of producing assets and expansion projects including Buckskin South.
LLOG operates ultra-deepwater drillships under long-term contracts with Seadrill (West Neptune and West Vela), engages subsea construction firms such as Subsea7 for development projects, and uses service providers like EnerMech for pre-commissioning work. The company's revenue model is commodity-based: oil and natural gas are sold to refineries, energy traders, and integrated oil companies at prevailing market prices (Brent crude and Henry Hub benchmarks), with no publicly disclosed pricing. Its go-to-market is B2B enterprise sales to upstream energy counterparties and commodity off-takers. In February 2026, LLOG was acquired by UK-based Harbour Energy for $3.2 billion ($2.7 billion cash plus $500 million in new shares), making it a wholly-owned subsidiary of a London-listed parent, with LLOG Holdings retaining an approximately 11% stake in Harbour Energy.
The company's customer base is diversified across downstream commodity buyers, but its geographic footprint is concentrated in the U.S. Gulf of Mexico. Following the Harbour acquisition, production is projected to grow to 65,000–70,000 boepd by 2028, supported by development projects such as Buckskin South and long-term drilling rig commitments. The leadership team is led by CEO Philip LeJeune.
