Our history in Alaska spans approximately 90 years since drilling our first well at Yakataga Beach in 1925. Since then, we have explored throughout Alaska including Cook Inlet, the Alaska Peninsula, St. George Basin, Norton Sound, Navarin Basin, Yukon Flats, Beaufort Sea and the North Slope.
Who We Are
ExxonMobil’s most important resource in Alaska is our people. On projects we lead, more than 85 percent of work to date has been performed by ExxonMobil employees based here in Alaska, or by local Alaskan contractors.

What We Do
ExxonMobil Alaska is one of the three largest producers in Alaska and the largest holder of discovered gas resources on the North Slope. According to the U.S. Energy Information Administration, there are 38.16 billion technically recoverable oil-equivalent barrels yet to be developed in Alaska as of 2011. These resources, including 25 trillion cubic feet of known natural gas resources at Prudhoe Bay, Point Thomson and other fields, could help meet Alaska’s in-state energy needs and could bring commercial volumes to the broader marketplace for generations to come.
ExxonMobil and its co-venturers have been producing from Prudhoe Bay for almost 40 years. An estimated 60 percent of the state’s remaining oil and gas resources are located there. We are working with our co-venturer and operator, BP, to progress development plans for the western region of greater Prudhoe Bay. We continue to invest in new wells and new programs to enhance future resource recovery, extend the life of the fields, and increase oil production in Prudhoe Bay and the other fields in which we participate in Alaska.
ExxonMobil is working to develop Alaska’s natural gas resources to compete on a global scale. As operator of Point Thomson and with our co-venturers in Prudhoe Bay, ExxonMobil is advancing a project to commercialize the vast North Slope gas resource. Development of the 8 trillion cubic feet of Point Thomson resources is essential to realizing the value Alaska’s North Slope natural gas reserves hold for the state. Learn more about Point Thomson.
ExxonMobil continues to work towards delivering Alaskan natural gas as a source of reliable and clean energy to global markets. That effort will provide a variety of benefits to Alaska, including new revenue, sustainable jobs, and business opportunities as well as facilitating new, long-term stable supplies of natural gas for Alaskans.
Where We Work
Point Thomson is located on state acreage along the remote Beaufort Sea, 60 miles east of Prudhoe Bay and 60 miles west of the village of Kaktovik. The Point Thomson reservoir holds an estimated 8 trillion cubic feet of natural gas and 200 million barrels of natural gas condensate, a high quality hydrocarbon similar to kerosene or diesel. The Point Thomson gas resources represent about 25 percent of known gas resources on the North Slope. ExxonMobil is developing initial facilities with the capacity to produce up to 10,000 barrels per day of natural gas condensate. A natural gas cycling facility is designed to remove this liquid condensate from the “wet” gas with the remaining gas then re-injected into the reservoir for future development. The condensate will then be transported by a 22-mile pipeline to the Badami pipeline and further to the Trans Alaska Pipeline System.

In early 1967, ExxonMobil and its exploration co-venturer Atlantic Richfield Company drilled the Prudhoe Bay State No. 1 discovery well, which turned out to be one of the most significant discoveries in the history of both Alaska and the United States. Today, the Prudhoe Bay unit contains the largest oil field in North America. Since production began in Prudhoe Bay in 1977, there have been more than 12 billion barrels of oil produced. Resources produced at Prudhoe Bay have been transported through the Trans Alaska Pipeline System.
ExxonMobil is the largest working interest owner of Prudhoe Bay, which is operated by BP. The Prudhoe Bay development includes more than 1,600 wells, 50 well pads, 1,300 miles of pipeline, seven major production separation facilities, a central gas facility, a central compressor plant, a central power station, a seawater treatment plant, and four active camps housing the more than 2,500 people employed as of January 2014.
ExxonMobil is a co-venturer in the Endicott oil field which is operated by BP and located in the Beaufort Sea, about 8 miles east of Prudhoe Bay. Endicott has the distinction of being the first continuously producing Arctic offshore oil development project. Discovered in 1978, Endicott is located 2.5 miles offshore in the Beaufort Sea and includes two man-made islands for drilling and production connected by an above ground pipeline to the mainland and the Trans Alaska Pipeline System. The Endicott Main Production Island started operating on October 3, 1987 as the first offshore Beaufort Sea production system, and continues to function today.
Kuparuk River Unit
ExxonMobil is an owner in the Kuparuk Unit that is operated by ConocoPhillips. Located west of the Prudhoe Bay Unit and discovered in 1969, the Kuparuk River Unit is the second largest oil field in North America. The field began producing in 1979. Project infrastructure includes 850 wells, three processing centers, 600 miles of surface pipeline, 41 drill sites, an operations center and industrial center, nine warehouses, and a seawater treatment plant.
Trans Alaska Pipeline System
In operation since 1977, the Trans Alaska Pipeline System cost more than $9 billion to construct and remains an impressive engineering feat to this day. The pipeline spans more than 800 miles from Prudhoe Bay on the North Slope to a marine terminal located at the port of Valdez on Alaska’s south coast. Along the way, the system includes a 360-mile, all-weather highway from the Yukon River to Prudhoe Bay, eight pump stations, a pressure relief station and the Valdez marine terminal.
More than 17 billion barrels of oil have been moved through the Trans Alaska Pipeline System since startup on June 20, 1977. ExxonMobil is an active co-venturer in the Trans Alaska Pipeline System.
In 2009, ExxonMobil acquired XTO which operates two platforms in Cook Inlet. Since acquiring the Middle Ground Shoal field from Shell in 1998, XTO has increased the remaining proven reserves of the field to 24 million barrels.
