Fracking Market to Grow 19% to $37 Billion Worldwide in 2012
By Joe Carroll Jan 19, 2012 5:34 PM ET

In North America, which accounted for 87 percent of the fracking market last year, spending on the technique used to extract oil and gas from shale will top $30 billion in 2012, said Richard Spears, vice president of the Tulsa, Oklahoma-based firm that advises about 400 oil producers, hedge funds, equipment providers and manufacturers.

Yes. I haven't claimed otherwise. But much of the hydraulic fracturing that is done in the US, is done by companies with international business work. It is not a secret US technology.

Maybe this will help.

Fracking Firms Face New Crop of Competitors

Schlumberger Ltd., Halliburton Co. and BJ Services, a company that is now a subsidiary of Baker Hughes Inc. once did nearly all the hydraulic-fracturing work in the U.S., helping energy companies unlock previously unreachable oil and natural gas in shale formations and ushering in a boom in domestic energy production.

But their profits attracted competition and spurred the construction of new fracking fleets by independent companies. Now their share of the market for pressure pumping—the main step in the fracking process, in which water and other materials are injected into a well to break apart rock formations and unleash oil or gas—has dropped off as smaller, cheaper competitors have proved they could do similar work.
