Halliburton Corporate Headquarters, Texas

Halliburton was founded in 1919 as an oil well cementing company by Erle P. Halliburton. In 1962, it acquired Brown and Root, an engineering and road construction company that had built the first offshore platform (in 1947). The Dresser and Kellogg companies (major pipe, field services, and refinery construction companies) were later merged into Halliburton, creating a diversified global leader in oil related construction, development and infrastructure. The company has since divested itself of its construction and engineering subsidiary, KBR, and is now focusing on energy services. With around 77,000 employees worldwide and $29 billion in revenue in 2013, it is among the largest oil services companies in the world. Halliburton announced it was opening a headquarters in Dubai, and though the CEO is now based there, the company maintains a major presence in Houston, with several complexes in the suburbs of the city, and a corporate office in its headquarters downtown.
