Since the confining tension improves, the increase in resistance to longitudinal crack propagation leads to a gradual transition of shale failure method from longitudinal to inclined shear failure that demonstrates an escalation in rock plasticity. Once the confining strain reaches thirty MPa, there remain area shear microcracks within the https://networkbookmarks.com/story21574997/an-unbiased-view-of-rock-mechanics-in-wellbore-stability
