Global Operations

Operating across the globe, Marathon is among the world's leading integrated energy companies - applying innovative technologies to discover and develop valuable energy resources, providing high-quality products to the marketplace and delivering value to all of the Company's stakeholders.

Exploration and Production
Marathon's exploration activities are focused on adding profitable production to existing core areas (United States, Equatorial Guinea, Libya and the North Sea) and developing potential new core areas (Angola and Indonesia).

Marathon's production operations supply liquid hydrocarbons and natural gas to the growing world energy market. Located in seven countries, worldwide production operations are currently focused in the U.S., Africa and Europe. The Company also holds ownership interests in both operated and non-operated oil sands leases in Canada that could be developed using in-situ methods of extraction.

Oil Sands Mining
Marathon owns a 20 percent outside-operated interest in the Athabasca Oil Sands Project (AOSP), which includes the Muskeg River Mine and the Scotford Upgrader, in Alberta, Canada. This asset gives Marathon access to stable, long-lived Organization for Economic Co-operation and Development (OECD) production that will be increased through several phased expansions over the next decade.

Integrated Gas
Marathon's integrated gas business adds value through the development of opportunities created by the growing demand for natural gas. The Company is linking stranded natural gas resources with areas where a supply gap is emerging due to limited production growth and increasing demand. Integrated gas complements Marathon's exploration and production operations and opens a wide array of investment opportunities designed to add sustainable value growth.

Refining, Marketing and Transportation
Marathon has extensive refining, marketing and transportation operations concentrated primarily in the Midwest, Upper Great Plains and Southeast regions of the U.S. Marathon ranks as the fifth largest crude oil refiner in the U.S. and the largest in the Midwest. Strategically located to serve major markets, Marathon's operations include a seven-plant refining network with 1,016,000 barrels per day of crude oil refining capacity, a comprehensive terminal and transportation system and extensive marketing operations.
