Awards and AccoladesEdit

In 2007, the Houston Chronicle ranked NOV the fifteenth best company to work for in Houston. In 2008, the newspaper ranked NOV as the best company in the city.[10] In the same year, NOV was listed as one of the world's most admired companies by Forbes and one of the 100 fastest growing companies by Fortune.[11] In 2009, NOV was again listed as one of the 100 fastest growing companies by Fortune and one of America's top companies by Forbes.

NOV's two main predecessors, Oilwell Supply and National Supply, were founded in 1862 and 1893, respectively. These two companies manufactured and distributed pumps and derricks. In 1930, United States Steel acquired Oilwell Supply. In 1958, Armco Steel merged with National Supply. In 1987, National Supply merged with USS Oilwell to become "National Oilwell".

Varco was founded as Abegg and Reinhold Company by Walter Abegg and Baldwin Reinhold in 1908. "VARCO" is an acronym for: Vuilleumiere, Abegg and Reinhold Company after Edgar Vuilleumiere became a partner in 1915, and Varco International in 1973. In 2000, National Oilwell merged with IRI International Corp., founded and managed by Hushang Ansary, which manufactures and sells drilling rigs and specialty steel products.[13]

In 2005, National Oilwell and Varco merged to become National Oilwell Varco. In 2014, Clay Williams took over as CEO, succeeding former CEO Pete Miller, who served as NOV's CEO for nearly 13 years.[14] Miller will become Executive Chairman of the National Oilwell Varco spinoff company, DistributionNow. The company employs nearly 64,000 people and has over 1,200 facilities across six continents worldwide.[15] In February 2012 NOV acquired a Russian coring company Interval Ltd.
