Marathon Oil Corporation is an American petroleum company that has existed since 1887. Marathon was founded in Lima, Ohio as the Ohio Oil Company. In 1899, the company was acquired by the Standard Oil Company (New Jersey). After the antitrust case against Jersey Standard in 1911 and subsequent breakup of its holdings, Ohio Oil once again became an independent company. In 1930, Ohio Oil acquired the Transcontinental Oil Company, which operated the "Marathon" brand of retail gasoline stations. Ohio Oil continued to use the Marathon brand, and in 1962, Ohio changed its name to the Marathon Oil Company.
In January 1982, Marathon was acquired by United States Steel. After the acquisition, the USX Corporation was created to act as the parent of U.S. Steel and Marathon Oil, which operated as divisions. In 2001, USX spun off Marathon under the name Marathon Oil Corporation. In 2011, Marathon Oil spun off its downstream operations as Marathon Petroleum. Since 2011, Marathon Oil has operated as an independent exploration and production company.
The company is ranked 534th on the Fortune 500[2] and 1900th on the Forbes Global 2000.[3] As of December 31, 2020, the company had 972 million barrels of oil equivalent (5.95×109 GJ) of estimated proven reserves, of which 86% was in the United States and 14% was in Equatorial Guinea.[1] The company's proved reserves consisted 52% of petroleum, 30% natural gas and 18% natural gas liquids.[1] In 2020, the company sold 383 thousand barrels of oil equivalent (2,340,000 GJ) per day, of which 26% was from the Eagle Ford Group, 27% was from the Bakken formation, 17% was from Oklahoma, 7% was from the Northern Delaware Basin, 2% was from other U.S. sources, and 20% was from Equatorial Guinea.[1]
On May 29, 2024, ConocoPhillips announced it was acquiring Marathon for $22.5 billion in an all-stock transaction, including debt.[4][5]
Marathon Oil began as "The Ohio Oil Company" in 1887.[6] In 1889, the company was purchased by John D. Rockefeller's Standard Oil. It remained a part of Standard Oil until Standard Oil was broken up in 1911. In 1930, The Ohio Oil Company bought the Transcontinental Oil Company and established the "Marathon" brand name. In 1962, the company changed its name to "Marathon Oil Company".[7]
In 1959, the Ohio Oil Company acquired Detroit based Aurora Oil Company which operated Speedway 79 stations and became an Ohio Oil subsidiary.[8]
In 1962, the Speedway 79 and Marathon stations were consolidated under the Marathon name and the Ohio Oil Company is renamed Marathon Oil Company.[9][10]

Since 2003, Marathon Oil and its partners Noble Energy and AMPCO, have invested in the Bioko Island Malaria Control Project (BIMCP) in Equatorial Guinea. The project includes distribution of insecticide nets, indoor residual spraying and larval source management, preventive therapy for pregnant women and malaria case management, and investment in a possible malaria vaccine. The project has resulted in a 63% reduction in malaria parasite prevalence and a 63% reduction in the mortality rate and 97% reduction in severe anemia in children under 5 years old.[30]
According to a 2017 study, the company was responsible for 0.19% of global industrial greenhouse gas emissions from 1988 to 2015.[31]
The company was investigated for payments made to Teodoro Obiang Nguema Mbasogo, the president of Equatorial Guinea.[32] The SEC completed its investigation in 2009 and did not recommend any enforcement action in the matter.[33]
