Given that the confining tension will increase, the increase in resistance to longitudinal crack propagation brings about a gradual transition of shale failure method from longitudinal to inclined shear failure that demonstrates an escalation in rock plasticity. Once the confining stress reaches thirty MPa, there are still regional shear https://read-review03680.ziblogs.com/42017288/the-2-minute-rule-for-wellbore-stability-issues
