The industry can no longer simply focus on the benefits of shale gas

George Mitchell, the pioneer of extracting shale gas economically, who died on July 26th, rarely talked to the press. In May 2012 The Economist conducted a written interview with him:

Fracking is an old technique, as is horizontal drilling. Geologists had long been aware of the huge reserves of shale gas. What made you decide that you could use the former to tap the latter? Had others before you tried and failed to make fracking and horizontal drilling economically viable?

Big oil companies knew the upside potential of shale gas, and many were working to economically extract the gas from the shale without much success. Many people were trying to make fracking work better, but they weren’t able to get the cells to give up the gas.

We knew there was gas in some of these shale fields. We would measure the volume of gas in the reservoir and it was very high methane (25-40% methane). You could get to the methane, but you couldn’t get it to leave the cells until you fractured it, and that was the major breakthrough.
