Given that the confining tension will increase, the increase in resistance to longitudinal crack propagation leads to a gradual transition of shale failure manner from longitudinal to inclined shear failure that displays an escalation in rock plasticity. When the confining tension reaches 30 MPa, there are still nearby shear https://vertechs21.weebly.com/blog/mastering-the-depths-how-vertechs-is-redefining-well-control-for-a-new-era-of-energy-security
