Description

Marathon Oil Corporation (NYSE:MRO) is an independent exploration and production (E&P) company focused on four of the most competitive resource plays in the U.S., complemented by a world-class integrated gas business in Equatorial Guinea. We became an independent E&P company on July 1, 2011 and we are based in Houston, TX.

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.

Marathon Oil Corporation, formerly a large independent exploration and production company, was acquired by ConocoPhillips in November 2024
