Test Shows Fracturing Can Also Create Underground Water Heating Systems
ResFrac customer, Fervo Energy has shown that fracturing can be used to build a geothermal heating system in hot, hard rock. During a 37 day test at it’s Project Red test site, the Houston company produced as much as 63 L/s (998 gal/min) of water heated to 336 degrees F. By pumping water from an injection well through fractured hot rock to a producing well, it heated enough water to generate up to 3.5MW of power, according to a company release.
