Marathon Oil Areas of Operation (click for map access)

United States
Our strategy is focused on lower cost, higher margin U.S. resource plays. With operations in four of the best oil-rich basins in the U.S., we are positioned for long term growth.
Bakken
We have been operating in the Williston Basin since 2006. The majority of our core acreage is within McKenzie, Mountrail and Dunn Counties in North Dakota targeting the Middle Bakken and ThreeForks reservoirs.
We continue focusing our investment in our high-return Myrmidon and Hector areas, while also delineating and extending our core acreage across the rest of our position.
The Bakken Formation is located in western North Dakota, eastern Montana, and southern Saskatchewan, Canada, as a subsurface formation within the Williston Basin. The Williston Basin extends to southwestern Manitoba, east-central North Dakota, northwestern South Dakota, eastern Montana, and southern Saskatchewan.
STACK/SCOOP
With a history in Oklahoma that dates back more than 100 years, our primary focus has been development in the STACK Meramec and SCOOP Woodford, while progressing delineation of other plays across our footprint.
We primarily hold net acreage with rights to the Woodford, Springer, Meramec, Osage and other prospect intervals, with a majority of this in the SCOOP and STACK.
STACK play is located in the Anadarko Basin area of Oklahoma. STACK is derived from “Sooner Trend (oil field), Anadarko (basin), Canadian and Kingfisher (counties).” The majority of the play is located across (Canadian and Kingfisher as the core counties) and Blaine, Major, Garfield counties. Unlike Plays such as the Eagle Ford, Bakken, Granite Wash, the STACK is not a geological formation, but a geographic referenced area.
We have been operating in the South Texas Eagle Ford play since 2011, where our acreage is located in the high-return Karnes, Atascosa, Gonzales and Lavaca Counties. Our focus is capital efficient development with a goal of maximizing returns and free cash flow generation.
We operate 32 central gathering and treating facilities across the play that support more than 1,600 producing wells. We also own and operate the Sugarloaf gathering system, a 42-mile natural gas pipeline through the heart of our acreage in Karnes and Atascosa Counties.
Eagle Ford in Texas is the most mature tight oil play in the Lower 48 current, oil and natural gas production of 2.5 million barrels of oil equivalent per day. Measuring 400 miles long and 50 miles wide along the Texas Gulf Coast, the Eagle Ford basin is spread over 12,000 square miles in South and central Texas.
Karnes County, TX ranks #5 in the state for BOE produced in the most recent month (Jun 2022). The information below is the summary of oil and gas data that goes back to 1993 and contains information on the 5,706 wells that have been drilled from Jan 1993 to Jun 2022.
Atascosa County, TX ranks #32 in the state for BOE produced in the most recent month (Jun 2022). The information below is the summary of oil and gas data that goes back to 1993 and contains information on the 4,231 wells that have been drilled from Jan 1993 to Jun 2022.
Gonzales County, TX ranks #20 in the state for BOE produced in the most recent month (Jun 2022). The information below is the summary of oil and gas data that goes back to 1993 and contains information on the 2,573 wells that have been drilled from Jan 1993 to Jun 2022.
We have been operating in the Northern Delaware basin, which is located within the greater Permian area, since closing on two major acquisitions in 2017.
Our focus has been to strategically advance our position, progress early delineation and development of our acreage, improve our cost structure and secure midstream solutions. We have the majority of our acreage in Eddy and Lea counties primarily in the Wolfcamp and Bone Spring New Mexico plays.
The Permian Basin, which spans western Texas and eastern New Mexico, represents the most prolific hydrocarbon production region in the United States. They accounted for about 30% of U.S. crude oil production and 14% of U.S. natural gas production (measured as gross withdrawals) in 2020. Technology innovations, such as longer lateral wells and multi-well pad drilling, has helped reduce costs and increase productivity in developing oil and natural gas resources in the Permian Basin.
Delaware Basin is a hydrocarbon rich sedimentary basin that lies within the Permian Basin. The Delaware Basin covers around 6.4 million acres in far West Texas and South Eastern New Mexico. It is located in an arid southwestern portion of the United States of America
