Eagle Ford

With major acquisitions in the Eagle Ford over the last several years, Marathon Oil has established a top-tier position in this liquids-rich resource play. As of year-end 2013, the Company held approximately 211,000 net acres in the Eagle Ford, with an average working interest of approximately 75 percent in its Company-operated assets.

The Eagle Ford Shale extends over 400 miles in South Texas, stretching northeast from the Mexican border near Laredo to beyond Houston, although the most active areas are south of San Antonio. Marathon Oil views the Eagle Ford as the premier U.S. resource play, and has invested strategically to grow its presence in the formation’s highest value oil and condensate core areas. Activity is focused on Atascosa, DeWitt, Gonzales and Karnes counties.


Primary base production areas in Texas include the Mimms Creek, Pearwood and Bridges East fields. The Company has more than 20,000 net acres in the Haynesville and Bossier Shale plays in East Texas and Louisiana, which is mostly held by production.
