The term “at the sharp end” could well have been coined for the companies that make up our list of the world’s 10 largest oilfield technology companies. Obviously there are countless technologies that go into the extraction of hydrocarbons from the ground, but actually drilling through rock is the one that everyone thinks of first.
What many people outside of the oil & gas industry don’t know however, is just how difficult getting to the precious black stuff can actually be. With many of the world’s largest oilfields maturing more and more technological wizardry is required to enable the oil producers to keep on churning out oil and gas for an ever-growing global market.
For this reason ArabianOilandGas.com decided to salute the companies who spend billions of dollars as well as millions of man hours on making the life of an average oil and gas worker productive, safer and easier.
What is interesting about the list is that the majority of the companies that are headquartered in Houston. It is obvious that developing innovative new technologies as well as manufacturing the more common garden oil & gas products is not something that any old Johnny-come-lately company can do. Most of these companies where around in various guises when Edwin Drake was drilling the first oilwell in the mid-1800s.
We used company revenues for 2008 as the criteria for the list and the information was sourced from each companies website and checked across news media where possible.
Of course as is always the case, if you agree with our top 10 or feel that another company was more worthy of a mention please leave a comment.

As a general oilfield services company Schlumberger is quite easily the largest in the world (see the Worlds 10 largest oilfield services companies for more details). Although the company operates across so many different parts of the oil & gas it still takes the top spot as the largest technology provider.
Schlumberger generated $27.16 billion of revenues in 2008, is registered in the Dutch Antilles and headquartered in Paris, Houston and The Hague. The CEO of the company is Andrew Gould and the company employs 82,000 people who operate in around 80 countries worldwide.
