Variation in the Permeability of Intact and Fractured Rocks due to Transient Disturbances in Axial Stress or Pore Pressure
Figure 12
Variation in permeability in each hydrostatic stress state (Hold-1, Hold-2, Hold-3, and Hold-4) at the time of transient pore stress disturbances for the whole experiment: (a) Pp-KCS1, (b) Pp-KCS4, (c) Pp-KCS6, and (d) Pp-KCS7. Dist. 1 and Dist. 2 are the disturbances in prefailure and postfailure, respectively.
