1. Schlumberger ($ 27.16 bn) Top 1 Biggest oilfield services company
When Conrad and Marcel founded the initial incarnation of Schlumberger in France back in 1926, I’m sure even they didn’t know that it would one day become the largest oilfield services company in the world.
Schlumberger now operates in around 80 countries and has a staggering 82,000 employees. The company, registered in the Dutch Antilles and headquartered in Houston, Paris and The Hague supplies numerous products and services including seismic acquisition and processing, formation evaluation, well testing and directional drilling, well cementing and stimulation, artificial lift, well completions and consulting, and software and information management.

2. Halliburton ($ 18.28 bn) Top 2 Biggest oilfield services company
Although Halliburton has to settle for second place, there is no doubt that due to various controversies over the last decade, the company is far more famous than an oilfield operator should. A view, if you read the various disclaimers on its website, shared by Halliburton themselves.
The company started out in 1919 specialising in cementing oil well walls in Texas. Today Halliburton has 57,000 employees and operates in around 70 countries. The company has dual headquarters in Houston and Dubai and provides technical products and services for oil and gas exploration and production.

The CEO of Halliburton, David J. Lesar, caused controversy in 2007 after announcing that he was moving to Dubai and would run operations from the Middle East. The move was believed to be in line with the company’s growth in the region. Lesar said at the time: “As the CEO, I’m responsible for the global business of Halliburton in both hemispheres and I will continue to spend quite a bit of time in an airplane as I remain attentive to our customers, shareholders and employees around the world.”
The move seems to have paid off and Halliburton has recently won some blue-chip contracts in the Middle East including Saudi Aramco’s Manifa offshore field and the giant Khurais field in the Saudi desert.
