Given that the confining force boosts, the increase in resistance to longitudinal crack propagation ends in a gradual transition of shale failure method from longitudinal to inclined shear failure that reflects an escalation in rock plasticity. If the confining force reaches thirty MPa, there remain regional shear microcracks within https://linkdirectory101.com/listings1183253/5-easy-facts-about-shale-wellbore-stability-described
