North Dakota

Marathon holds approximately 350,000 net acres in the Bakken oil play in North Dakota and eastern Montana. The Company’s acreage is within the established Williston Basin in Dunn, McKenzie, McLean, Mountrail and Williams counties in North Dakota, and Richland County in Montana, with net potential resources of more than 150 million barrels of oil equivalent.

The position provides Marathon access to significant resources in North America. The Company draws upon its extensive experience in reservoir characterization, horizontal drilling, well stimulation, operational execution and commercial and marketing expertise in the Rocky Mountain Basins to leverage this substantial position in the Bakken play.

Drilling commenced in May 2006, leading to first production from Marathon-operated Bakken wells in August 2006. The Company currently has five rigs drilling in the Basin. Marathon anticipates drilling approximately 264 gross wells over the next five years (61 during 2010, including four technology project wells), with the potential to have approximately 22 mboepd of net peak production by 2013.
