Another kind of ‘fracking’, this produces geothermal energy

"In fall 2012, Geodynamics Ltd. tested a 2.6-mile-deep well at its Habanero enhanced geothermal pilot project in Australia. The well produced a strong flow of steam with surface temperatures of 375 degrees Fahrenheit and higher.
.....Zoback also will also discuss challenges facing the emerging shale gas industry. “The shale gas revolution that has been under way in North America for the past few years has been of unprecedented scale and importance,” he said. “As these resources are beginning to be developed globally, there is a critical need for fundamental research on such questions as how shale properties affect the success of hydraulic fracturing, and new methodologies that minimize the environmental impact of shale gas development.”
Approximately 30,000 shale gas wells have already been drilled in North America, he added, yet fundamental challenges have kept the industry from maximizing its full potential. “The fact is that only 25 percent of the gas is produced, and 75 percent is left behind,” he said. “We need to do a better job of producing the gas and at the same time protecting the environment.”
