PayRock’s resource potential upside estimates
According to Marathon Oil’s estimates, PayRock acreage has a total resource potential upside up to ~700 MMboe. This is from increased well density in the Meramec and Woodford target areas and the development of the Osage target area.
As of December 31, 2015, Marathon Oil’s 1P (proved reserves) resource totaled 2,163 MMboe.
