Marathon Oil Corporation engages primarily in the exploration, production, and marketing of crude oil, natural gas liquids, and natural gas. The company’s core products include crude oil and gas condensates, natural gas, liquefied natural gas, and related hydrocarbon liquids, with operations mainly in the United States and internationally, particularly in Equatorial Guinea and the United Kingdom. Marathon Oil also owns and operates the Sugarloaf gathering system, a natural gas pipeline. Founded in 1887 and headquartered in Houston, Texas, the company operates as an independent international energy firm focusing on upstream oil and gas activities.
Recent major changes for Marathon Oil include its acquisition by ConocoPhillips, completed in late 2024, which positioned Marathon Oil as a subsidiary under ConocoPhillips. Despite the acquisition, Marathon Oil has continued to raise production guidance based on strong well productivity and efficiency gains, with 2024 production approaching 192,000 net barrels of oil per day and 393,000 net barrels of oil equivalent per day. The company has also maintained capital spending plans consistent with these production targets while optimizing free cash flow generation. Marathon Oil continues strategic efforts to expand and optimize its U.S. and international upstream operations post-acquisition, leveraging ConocoPhillips’ broader portfolio and resources.
Marathon Oil serves primarily exploration and production (E&P) markets, focusing on oil and gas upstream segments. The company’s geographic footprint includes significant operations in the United States, accounting for the majority of sales, along with international activities in regions such as Africa and the UK. Marathon Oil markets its hydrocarbons both directly and through related infrastructure assets such as pipelines, aiming to maintain a strong presence in core basins and emerging international areas. The acquisition by ConocoPhillips marks a significant operational and strategic milestone, providing access to expanded capital and operational synergies.
Overall, Marathon Oil Corporation offers crude oil, natural gas liquids, and natural gas exploration and production services with recent strategic integration into ConocoPhillips, emphasizing production growth and operational efficiency within the U.S. and select international markets, headquartered in Houston since its establishment in 1887.
