Operational Excellence

StrategyU.S. Resource Play Focused

Since 2011, Marathon Oil has strengthened our position as an independent E&P with a substantial shift in focus
to the lower cost, higher margin opportunities in the U.S. resource plays.

Our 2017 entry into the Northern Delaware in the Permian basin and exit from Canadian oil sands operations have further simplified and concentrated our portfolio. 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.
