General information

Marathon Oil explored for and produced crude oil, natural gas and oil sands. It ran commercial gas and power operations and also worked in liquefied natural gas, known as LNG. The company was first established in 1887 as The Ohio Oil Company in Lima, Ohio. Marathon Oil was based in Houston, Texas.

ConocoPhillips, a rival oil company, bought Marathon Oil in November 2024 in a deal worth $22.5 billion. Marathon Oil then became defunct on November 22, 2024. Someone looking at this page today would see a company that no longer operates on its own. Its business now runs inside ConocoPhillips. Marathon Oil is an H-1B sponsor.1
