... ABSTRACT: Most conventional rock mechanics tests have their origin in civil engineering, where design rules necessarily dictate a conservative approach. For the petroleum industry applications however, partial rock failure may be acceptable in order to optimize design. If such approaches...

The drastic permeability increase is due to the sudden rock failure in which...
