Marathon at a Glance
Marathon at a Glance, world map of operations
Marathon (NYSE:MRO) is an integrated international energy company with expertise in exploration and production; integrated gas; and refining, marketing and transportation. Headquartered in Houston, Texas, Marathon is the fourth-largest U.S.-based fully integrated energy company. Marathon has principal exploration and production activities in the United States, the United Kingdom, Angola, Canada, Equatorial Guinea, Gabon, Ireland, Norway and Russia. Marathon is a leading refiner and marketer in the United States through a 62 percent interest in Marathon Ashland Petroleum LLC (MAP).
Exploration: Exploration: Marathon’s exploration activities are focused on adding profitable production to existing core areas in the United States, Equatorial Guinea and the North Sea, and to developing potential new core areas in Angola and Eastern Canada.

Production: Marathon’s production operations, based in seven countries around the world, supply products to the growing world energy market. Worldwide operations are focused in four core areas: the United States, Europe, West Africa and Russia. In 2004, worldwide daily production averaged 170 mbpd of liquids and 999 mmcfd of natural gas, or 337 mboed. U.S. production accounted for 55 percent of the Company’s worldwide production with investment focused on the mid-America gas corridor and the Gulf of Mexico. Another 26 percent of worldwide production originated in Europe with investment focused on offshore fields in the North Sea and Ireland.
     Key production investments continue in Equatorial Guinea, where the Company has completed projects that are expected to significantly increase gas condensate and liquefied petroleum gas (LPG) production, and in Norway, where the Company is proceeding with the Alvheim and Vilje developments. In addition, Marathon has investments in production growth and development projects in Russia and Ireland
   Working to add value through opportunities created by the world’s growing demand for natural gas, Marathon is developing integrated gas projects to link stranded natural gas resources with key demand areas where domestic production is declining and demand is growing — particularly in North America.
     Marathon is commercializing world-class natural gas reserves offshore Equatorial Guinea with construction of a liquefied natural gas (LNG) plant, which is projected to produce 3.4 million metric tonnes of LNG per year beginning in late 2007.
     Marathon has LNG long-term delivery rights at Elba Island, Georgia, of up to 58 bcf per year. The Company recently secured a five-year LNG supply agreement that will fully utilize its capacity in the Elba Island terminal beginning in the second half of 2005.
     Marathon’s interest in the Atlantic Methanol Production Company LLC (AMPCO) in Equatorial Guinea delivered record volumes during a period of strong prices.
     Marathon’s integrated gas business builds upon more than 30 years of LNG experience gained from the Company’s interest in the first and only LNG export operation in the United States, located in Kenai, Alaska.
     Marathon is also engaged in gas-to-liquids (GTL) technology development, which has resulted in a process capable of converting natural gas into ultra-clean fuels.
  Refining, Marketing and Transportation:
Marathon refines, markets and transports crude oil and petroleum products, primarily in the Midwest and Southeast regions of the United States, through MAP, in which Marathon holds a 62 percent interest.
     MAP operates seven refineries with a total capacity of 948,000 bpd. MAP’s refineries process a wide variety of crude oils into many refined products, including gasoline, distillates, asphalts, feedstocks and special products. MAP operates 84 light product and asphalt terminals and markets refined products in 17 states.
     MAP supplies motor fuel to approximately 3,900 independently-owned and -operated Marathon brand stations. In addition, MAP owns Speedway SuperAmerica LLC, the third-largest chain of company-owned and-operated retail gasoline outlets in the nation with approximately 1,670 locations. MAP also has a 50 percent interest in Pilot Travel Centers LLC, which is the largest company-owned and -operated travel center network in the United States with approximately 250 locations. In addition, MAP owns, operates, leases or has interest in approximately 7,700 miles of crude and refined product pipelines, an extensive inland barge distribution network and a 46.7 percent interest in the Louisiana Offshore Oil Port, the nation’s only deepwater oil port.
