... large in the near wellbore region. The experimental programme was performed to examine the changes in two-phase permeability during deformation. This consisted of experiments where, starting from a given hydrostatic stress level, σ 1 was increased until the rock failed and a shear fault was formed...

... depends on the bottom-hole pressure p m and not on the virgin pore pressure p o . Single cutter experiments performed by Zijsling 1 support this conclusion. His experimental data show that s is indeed independent of p o and that it varies linearly with p m . TABLE 1 LIST...

... that the fracture behaviour is highly sensitive to its degree of "matedness". The measured significant variation in permeability during creep does not seem compatible with the measured small reduction in fracture aperture. The preliminary test results demonstrate the experimental difficulties in obtaining reliable...
