Description/Abstract:From 20th international instrumentation symposium; Albuquerque, New Mexico, USA (21 May 1974). Initial measurements to evaluate the feasibility of extracting energy from hot-dry rock in Precambrian basement (granite) employing hydraulic-fracturing techniques were explored in the LASL Granite Test Hole No. 1. Following a series of hydrology experiments in the 785-m (2575 ft) depth hole, preparations were made to instrument a series of hole-pressurization and hydraulicfracturing experiments. The instrumentation was designed to measure breakdown pressure, crack-extension pressure, and shut-in pressure for each fracture and to determine principle tectonic stresses, breakdown stress for hydraulic fracturing, and leak-off rate for fracturing fluid.
