GEOTHERMAL HOT DRY ROCK - Energy
hot, impermeable, crystalline basement rock. The hydraulic fracturing, achieved by pumping water into the well at high pressure, forces open tiny pre-existing fractures in the rock, creating a system or "cloud" o f frac tures that extends for tens of meters around the well. The body of rock containing the fracture syste m is the reservoir of heat.
