Welcome
As of 2011, Marathon Oil Corporation and Marathon Petroleum Corporation are two completely separate entities — each positioned to deliver continued shareholder growth.
Marathon Oil

We’re focused on the most significant oil-rich resource plays in the U.S. — the Eagle Ford in Texas, Permian in New Mexico, STACK and SCOOP in Oklahoma, and the Bakken in North Dakota. We also have international operations in Equatorial Guinea. Our stock trades on the New York Stock Exchange under the ticker symbol: MRO.
