As the confining tension boosts, the rise in resistance to longitudinal crack propagation leads to a gradual changeover of shale failure method from longitudinal to inclined shear failure that demonstrates an escalation in rock plasticity. In the event the confining tension reaches 30 MPa, there are still regional shear https://fluidrheology90086.wikihearsay.com/4594366/how_wellbore_stability_can_save_you_time_stress_and_money
