Positioned for Profitable GrowthSTACK/SCOOP, Oklahoma

About the PlaySTACK/SCOOP

Oklahoma is a top priority for Marathon Oil, and there’s no doubt that the evolving STACK play in the Anadarko Basin is one of the best unconventional oil plays in the U.S. But our history in Oklahoma dates back for more than 100 years. More recently, we’ve been building a portfolio of high-return drilling opportunities that provide a platform for robust future growth here.

At year-end 2016, we held approximately 365,000 net surface acres in the Oklahoma Resource Basins. In the STACK and SCOOP areas, we’re in the Woodford, Springer, Meramec, Osage, Oswego, Granite Wash and other Pennsylvanian and Mississippian plays.


Latest Activity3Q 2017

Our unconventional Oklahoma production averaged 58,000 net boed during 3Q 2017. That’s up 18% over 2Q 2017, and more than 40% higher than a year ago. We brought 15 gross Company-operated wells to sales during the quarter predominately focused on leasehold capture and delineation activity. For the balance of the year we expect to bring 20-25 wells to sales, about 40% of which will be leasehold protection.
