For Marathon Oil, the primary focus in Oklahoma has been delineation and leasehold protection in the Meramec play in the STACK and delineation of the Woodford and Springer plays in the SCOOP, as it moves toward infill development.
The company holds 300,000 net surface acreage with rights to the Woodford, Springer, Meramec, Osage, Oswego, Granite Wash and other Pennsylvanian and Mississippian plays, with a majority of this in the SCOOP and STACK.

Marathon Oil’s Oklahoma production averaged 80,000 net boed during second quarter 2018, up 7 percent from 75,000 net boed in the prior quarter. In the SCOOP, the Company brought on the four-well Woodford Lightner infill pad on 660-foot spacing across a half section, with an average 30-day IP rate of 2,620 boed (48% oil, 6,840-foot average lateral length). The pad’s IP rate and oil cut both exceeded expectations. In the STACK, four Meramec wells in the Siegrist infill pad achieved an average 30-day IP rate of 900 boed (71% oil, 4,505-foot average lateral length), meeting expectations with strong oil rates. Marathon Oil also signed a firm transportation agreement for 100 million cubic feet per day beginning in fourth quarter 2018 to protect near-term natural gas production and bridge to the start-up of the Midship Pipeline on which Marathon Oil is an anchor shipper.
