Unocal Corporation - History

History

The Union Oil Company of California was founded on October 17, 1890, in Santa Paula, California, by Lyman Stewart, Thomas Bard, and Wallace Hardison. It was a merger of three Southern California Oil Companies: the Sespe Oil Company, the Hardison and Stewart Oil Company, and the Mission Transfer Company. All three were notable as being completely unaffiliated with Standard Oil. Union Oil moved its headquarters to Los Angeles, in 1901. The original headquarters in Santa Paula is a California Historical Landmark.

About 1910, Union Oil made a strategic alliance with the Independent Producers Agency, a group of small oil producers, to build pipelines from the Kern County oil fields to Union Oil facilities on the Pacific coast. This gave the independent producers an alternative to what they perceived as the low prices paid by Standard Oil and the high freight rates charged by the railroads to move crude oil. It gave Union access to a large volume of crude oil. The situation was later fictionalized in the 2007 film There Will Be Blood.

In 1919, the Union Oil Company of Delaware was incorporated as a holding company for the Union Oil Company of California. In 1920, Union Oil purchased the Central Petroleum Company from the Texas Company. In 1922, the Union Oil Associates, Inc. was incorporated in California as a holding company to prevent control of the Union Oil Company of California passing to foreign interests after the merger of the Union Oil Company of Delaware with Royal Dutch Company.

The company expanded to national status in 1965, when Union Oil merged with the Pure Oil Company, headquartered in what was then Palatine, Illinois and now Schaumburg, Illinois. Over the next two decades, Union became the major oil producer in southern Alaska and a major natural gas producer in the Gulf of Mexico. The company was reorganized in 1983, and Union Oil Company of California became an operating subsidiary of a new Delaware-based holding company, Unocal Corporation. In 1985, Mesa Petroleum, controlled by billionaire T. Boone Pickens, attempted a takeover of Unocal Corp. that resulted in the Delaware Supreme Court landmark decision Unocal v. Mesa Petroleum, which upheld Unocal's takeover defense. Virtually all operations are conducted by Union Oil Company of California (Union Oil).

In 1977, Unocal acquired The Molybdenum Corporation of America (now Molycorp). Among the assets acquired was Mountain Pass rare earth mine, a then world's largest producer of rare earth elements.

In 1989, Unocal placed its midwest refining and marketing assets, including Union's 150,000-barrel-per-day (24,000 m3/d) refinery in Lemont, Illinois, into a 50/50 joint venture with Petróleos de Venezuela, S.A. (P.D.V.S.A.). The joint venture, known as the Uno-Ven Company, was headquartered in Arlington Heights, Illinois and primarily comprising employees from Union Oil's then Schaumburg, Illinois, division headquarters and Lemont, Illinois, refinery. The joint venture was dissolved in 1997, with P.D.V.S.A. receiving full ownership. During the life of the joint venture, the familiar Union 76 brand name continued in full force. At the termination of the joint venture, most stations were converted to Citgo, which is controlled by P.D.V.S.A.

In 1997, Unocal sold its western United States refining and marketing operations to Tosco Corporation, including the rights to the Union 76 brand for refining and marketing (except in states where Uno-Ven operated). Tosco was later acquired by Phillips Petroleum who later merged with Conoco to form ConocoPhillips.
