New experiments in the deserts of Utah and Nevada show how advances in fracking—technology developed by the oil industry—can be repurposed to tap clean geothermal energy anywhere on Earth.
returned to Beaver County to drill well number two. After nearly a year of reviewing the data from the initial frack, he felt confident that the production well, drilled straight through the cloud of cracks from the frack, would succeed in getting water back out. Earlier this month, he was proved right: Nearly 76,000 gallons went down the first hole at a rate of about 210 gallons per minute, and came back out the other end hotter.
In the end, all three were less useful than Moore had hoped. The particle drilling and steerable system turned out to be more trouble than they were worth, especially compared with the earlier success of the diamond-tipped bits. The modified geophones still fritzed beyond about 300 degrees Fahrenheit ; Moore says they’ll eventually switch over to heat-proof, fiber optic-based devices. But that’s the point, he says, of “de-risking.” Sometimes it’s helpful to see what breaks.
