Operational Excellence

StrategyU.S. Resource Play Focused

Marathon Oil has transitioned from portfolio transformation to execution delivery at scale across our U.S. resource plays. With more than 90% of our 2018 development capital allocation associated with the U.S. resource plays, our margins will naturally expand as a greater percentage of our production is sourced from these high quality assets.

Eagle Ford


Our relentless focus on portfolio management has driven seven country exits since 2013 and generated proceeds of more than $4 billion just in the last 2 years.

With our 2017 entry into the Northern Delaware in the Permian basin, we now enjoy a differentiated position as the only E&P active in the four best oil-rich U.S. resource basins.

Though many elements of our business are changing, one thing remains firm: our values. We remain steadfast in our commitment to be safe, responsible and ethical.

We thank all our dedicated employees who make such a difference in driving execution excellence. Their talent and innovation will continue to position us favorably through 2018 and beyond.
