10 Biggest Offshore Drilling Companies in the U.S.

Posted in High Seas, High Risk: Offshore Injury on August 17, 2015

The offshore drilling market accounts for a huge amount of the world’s wealth. The opening of the U.S. Atlantic, Pacific, and the Gulf of Mexico for offshore oil exploration will have significant effects on the United States. This development is expected to generate an additional $70 billion per year for the U.S. economy and create an estimated 840,000 new jobs. At the moment, the federal government controls these three regions, and 87% of the acreage is off limits for offshore oil and gas development. That means these top 10 oil-drilling companies are not making nearly as much as their potential if these regions are opened. Still, the revenue they do make is quite hefty. Here are some recent figures:

  • Schlumberger. The biggest offshore drilling company, not just in the U.S. but in the world, beat its own revenue record last year. Its revenue increased 7% from 2013, totaling a whopping $48.6 billion dollars last year. Schlumberger’s headquarters are in Houston, TX.
  • Halliburton. Coming in second is Halliburton, based out of Houston, TX and Dubai, India. It is one of the world’s largest oil drilling companies, representing more than 140 nationalities and 80 countries. Its revenue grew 12% from 2013, totaling $32.9 billion last year.
  • Baker Hughes. Also based in Houston, TX, Baker Hughes had substantial revenue growth last year also. Up from 10% in 2013, the oilfield services company made $24.6 billion last year. The company is known for its innovative and technologically advanced approach to complex drilling situations.
