{{Projet:Traduction/{{PAGENAME}}|Paramètre=Cacher}}

'''Valero Energy Corporation''' ({{nyse|VLO}}) is a [[Fortune 500]] company based in [[San Antonio, Texas|San Antonio]], [[Texas]] with 21,836 employees and annual revenue of more than $90 billion. The company owns and operates 17 [[Oil refinery|refineries]] throughout the [[États-Unis|United States]], [[Canada]] and the [[Caribbean]] with a combined throughput capacity of approximately 3.3 million [[Barrel (unit)|barrels]] per day, making it the largest refiner in [[North America]]. Valero is also one of the nation's largest retail operators with more than 5,000 retail and branded wholesale outlets in the United States, Canada and the Caribbean under various brand names, including Valero, Diamond Shamrock, Ultramar, Shamrock and Beacon.

==Retail==
Valero also retails [[gasoline]] branded as ''Valero'', ''[[Shamrock Oil|Shamrock]]'', ''[http://www.tsha.utexas.edu/handbook/online/articles/DD/dod3.html Diamond Shamrock]'', ''Ultramar'', ''Beacon'', and ''Total''. While this arm of the company is the most visible to the public, it is, according to CEO [[Bill Klesse]], "a very small part of [Valero's] operations"[http://www.marketwatch.com/news/yhoo/story.asp?source=blq/yhoo&siteid=yhoo&dist=yhoo&guid=%7B2EEF79CA%2D2302%2D4C16%2D8087%2D07A21B521581%7D].

Valero is gradually shifting its focus from being a [[Filling station#Types of filling stations in the US|discount gasoline brand]] to becoming a premium brand. As part of that shift, Valero has begun to [[rebranding|rebrand]] its Ultramar, Beacon, Total and Diamond Shamrock stations to the ''Valero'' brand. The ''Beacon'' and ''Shamrock'' brands are used by retailers as a low cost alternative to the premium Valero brand. (The ''Shamrock'' brand, in the Valero empire, is based on the former [[Shamrock Oil]] and Gas Company, which merged with Diamond Alkali in 1967 to form Diamond Shamrock.) The name ''Ultramar'', while being eliminated in the U.S., will still be used as Valero's brand name in Canada.

==History==
Valero was created on [[January 1]], [[1980]], as a spinoff from the [[Coastal States Gas Corporation]]. At the time, it was the largest corporate spinoff in U.S. history. Valero took over the [[natural gas]] operations of the LoVaca Gathering Company, a defunct subsidiary of Coastal States Gas. The name Valero comes from ''Misión San Antonio de Valero'', the mission founded in 1718 from which the city of San Antonio started, which is better known worldwide as [[Alamo Mission in San Antonio|The Alamo]].

The company acquired a small oil refinery in [[Corpus Christi, Texas]] in [[1981]], and began refining operations in [[1984]].

In [[1997]], Valero spun off its refining and retail divisions into a separate company, which kept the Valero name. At the same time, the remaining divisions, which consisted primarily of natural gas operations, were acquired by [[PG&E]]. Later that year, Valero acquired [[Basis Petroleum]], which left it with four refineries in [[Texas]] and [[Louisiane]].

Valero acquired a [[Paulsboro, New Jersey]] refinery in [[1998]]. This was the company's first refinery outside of the [[Gulf Coast]] area.

In [[2000]], Valero purchased [[ExxonMobil]]'s [[Benicia, California]] refinery and interests in 350 ''Exxon''-branded service stations in [[Californie]], mainly in the [[San Francisco Bay area]]. The company also began retailing gasoline under the ''Valero'' brand. In June [[2001]], the company acquired the [[Huntway Refining Company]], along with two asphalt plants on the west coast.

On [[December 31]], [[2001]], Valero completed its acquisition of Ultramar Diamond Shamrock. This merger left Valero with over 4,700 retail sites in the U.S., Canada, and the Caribbean. With this acquisition Valero also received ownership of Shamrock Logistics L.P., which was renamed [[Valero L.P.]] This [[limited partnership]] owns and operates a 7200 mile (11500 km) pipeline network and 57 refined product terminals in the U.S., and is publicly traded (Valero maintained a 13.6 percent indirect interest through [[Valero GP Holdings, LLC]], also publicly traded, which in 2006 it fully divested).

Starting in [[2002]], Valero has been expanding its marketing to the East Coast, specifically the Northeast and [[Floride]], using the Valero brand.

On [[April 25]], [[2005]] Valero agreed to buy [[Premcor]] Inc. for $6.9 billion in cash and stock to become the largest U.S. refiner, as record prices for gasoline and other fuels boost profits.

On [[June 30]], [[2005]] Valero announced it was beginning a two-year process of converting Diamond Shamrock stations to the Valero brand.
