United States

ExxonMobil has had a presence in the United States since 1870 when John D. Rockefeller and his associates formed the Standard Oil Company (Ohio), with combined facilities constituting the largest refining capacity of any single firm in the world. Today, Exxon Mobil Corporation is the largest publicly traded international oil and gas company and holds an industry-leading inventory of resources. We are also the largest refiner and marketer of petroleum products, and our chemical company is one of the largest in the world.


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.
