Alaska

Marathon has been exploring for, and developing hydrocarbons in Alaska for more than 50 years, with exploration activities focused on natural gas.

Based in Anchorage, the Company ranks as one of the largest natural gas producers in the Cook Inlet region of South Central Alaska and the adjacent Kenai Peninsula. Since 1998, the Company has drilled more than 60 gas wells in the Cook Inlet.

Cook Inlet 

Marathon joined with local contractor Inlet Drilling in 2000 to design a high-specification drilling rig, the Glacier Drilling Rig No. 1, to expand our business operations cost-effectively and with low environmental impact.

The company acquired more than 600 miles of 2-D seismic survey and acquired nearly 14,000 leasehold acres through an exploration agreement with Cook Inlet Region Inc. — an Alaska native corporation. This acreage included five exploration prospects and two natural gas discoveries made by Marathon at Sterling Deep and Wolf Lake Field, located within the Kenai National Wildlife Refuge. Wolf Lake was the first Cook Inlet gas field discovery to be brought to market since 1979, and first production was announced in 2001.

Ninilchik

The Ninilchik Field, which began natural gas production in 2003, is on the Kenai Peninsula, approximately 35 miles south of Kenai, Alaska. The gas is transported through the Kenai-Kachemak Pipeline, which connects Ninilchik to the existing natural gas pipeline infrastructure.

This infrastructure serves residential, utility and industrial markets on the Kenai Peninsula, in Anchorage and in other parts of south central Alaska. Marathon is operator of the Ninilchik unit with a 60-percent interest.

Delivery Commitments

Marathon has commitments to deliver fixed and determinable quantities of natural gas to customers under a variety of contractual arrangements. Marathon has a 30 percent ownership interest in the Kenai LNG plant and a proportionate share of the long-term LNG sales obligation to two Japanese utility companies, Tokyo Electric Power Company and Tokyo Gas Company Ltd.—two of Japan’s largest utility firms.
