12 We report on laboratory experiments designed to investigate the effect of 13 dynamic stressing on permeability of fractured rock. Berea sandstone samples 14 were fractured in-situ under triaxial stresses of 10's of MPa, and deionized 15 water was forced through the incipient fracture under conditions of steady and 16 oscillating pore pressure. We find that dynamic stresses produced by pore 17 pressure oscillations induce transient increases in effective permeability. The 18 magnitude of… CONTINUE READING
