Evan’s hole

Figure 5.3 bands of an isolated H-bond in a gas, a liquid and a crystal. An Evan s hole due to a Fermi resonance is added in the middle spectrum as a thin line. In the bottom spectrum, the -phonon components are drawn as thin lines.

A major hydraulic fracturing experiment was performed in September and October 1993 at Soultz-sous-Forets. In the September test, 25,000 m of fresh water were injected between 2850-3350 m at progressively higher rates to 40 1/s and pressures of up to 10 MPa over a 17 day period. In October, a further 20,000 m of water were injected at up to 50 l/s into the entire open hole section. Through the test, it was demonstrated that the fracture network in the basement rock was well developed, with enhanced permeability and a substantial increase in transmissivity (Baria et al., 1999 Evans, 2000).
