Tesoro Corporation, known briefly as Andeavor, was a Fortune 100^[4] and a Fortune Global 500 company headquartered in San Antonio, Texas, with 2017 annual revenues of $35 billion, and over 14,000 employees worldwide. Based on 2017 revenue, the company ranked No. 90 in the 2018 Fortune 500 list of the largest United States corporations by total revenue.^[5]

Tesoro was an independent refiner and marketer of petroleum products, operating ten refineries in the Western United States with a combined rated crude oil capacity of approximately 1200000oilbbl per day. Tesoro's retail-marketing system included approx. 3,000 branded retail gas stations, of which more than 595 were company-operated under its own Tesoro brandname, as well as Shell, ExxonMobil, ARCO, and USA Gasoline brands.

Tesoro, known at the time as Andeavor, was acquired by Marathon Petroleum on October 1, 2018.

History

Tesoro was founded in 1968^[6] by Dr. Robert Van Osdell West Jr (1921–2006),^[7] and was primarily engaged in petroleum exploration and production. Tesoro began operating its first refinery, near Kenai, Alaska, in 1969. Tesoro became the first Fortune 500 company to be headquartered in San Antonio, Texas. Tesoro is the word for treasure (or treasury) in Italian and Spanish.

Beginning in the late 1990s, Tesoro grew through a series of acquisitions and initiatives that created Tesoro Corporation, the company focusing on the core business of petroleum refining, marketing, maritime transportation and distribution. The first segment involved the operation of six petroleum refineries situated in California, Alaska, Washington, Hawaii, North Dakota, and Utah.^[8] For its marketing and distribution segment, Tesoro sold refined gas and fuel products in both bulk and wholesale markets. Acquisitions expanded refining capacity from 72000oilbbl/d to approximately 664000oilbbl/d.

Prior to its acquisition by Marathon Petroleum in 2018, Tesoro was the third-largest independent petroleum refining and marketing company in the United States. The merger between the two companies formed the largest American refiner by capacity and the fifth in the world.^[9]

Milestones in Tesoro's history are:

Media controversy

Environmental record

Having taken over BP installations, researchers at the Political Economy Research Institute identified Tesoro as being the 24th-largest corporate producer of air pollution in the United States, releasing roughly 3740000lb of toxic chemicals annually.^[22] Major pollutants emitted annually by the corporation were estimated to include more than 400000lb of sulfuric acid,^[23] following which the Environmental Protection Agency named Tesoro a potentially responsible party for at least four superfund toxic waste sites.^[24] Tesoro settled and/or closed each of the superfund sites where it was named as one of many responsible parties. Tesoro was listed as a de minimis contributor to a superfund site in Abbeville, LA, and the site has since been closed by the EPA.

Tesoro gave over $1 million in support of California Proposition 23, which aimed to suspend the Global Warming Solutions Act of 2006.^[25]

Defenders of the Amazon forest in South America cite Tesoro for sourcing some of their crude oil from the Amazon. Three of Tesoro's refineries - Anacortes (WA), LA (CA) and Golden Eagle (CA), were known to process Amazonian crude oil.^[26]

Explosion

See main article: 2010 Tesoro Anacortes Refinery disaster.

On April 2, 2010, an explosion at Tesoro's refinery in Anacortes, Washington, killed seven workers.^[27]

Hawaii refinery

Tesoro bought Libyan crude oil, after the overthrow of Colonel Gaddafi, in early April 2011 from the Vitol Group to supply its then-Hawaiian refinery.^[28]
