Get to know Marathon Oil
We are a responsible, independent E&P with deep roots in American energy.
Overview
Marathon Oil became an independent E&P company on July 1, 2011. Based in Houston, we're focused on the most significant oil-rich resource plays in the U.S. -- the Eagle Ford in Texas, the Bakken in North Dakota, the STACK and SCOOP in Oklahoma, and the Permian in New Mexico. We also have international operations in Equatorial Guinea.
We know our stakeholders are particularly attuned to environmental, social and governance issues, often referred to as “ESG.” Because of this, we’ve prioritized and improved how we communicate our sustainability work through our annual sustainability report which showcases our efforts to achieve safe, responsible and ethical operations.
Last year, we made a commitment to work safer and we succeeded. 2019 marked the best safety performance in MRO history with a peer leading total recordable incident rate (TRIR) of 0.32.
Our Strategy
Marathon Oil remains committed to our framework for success, with the foundation of a peer leading balance sheet and the competitive advantages of our multi-basin portfolio.
We have the right portfolio of assets and the right strategy: putting returns first, generating sustainable free cash flow at conservative oil prices and sharing that cash flow with investors.

Delivering value since 1887.
While we feel like a start-up in many ways, our roots go back 130 years to our company's formation in 1887.
From the beginning, we focused on oil production, starting as the Ohio Oil Company. We operated as an integrated oil company for nearly 90 years of our history. In 2011, we spun off the refining business and became an independent E&P company.
It’s not just a phrase. It’s a way of life.
