Because the confining tension will increase, the rise in resistance to longitudinal crack propagation ends in a gradual transition of shale failure mode from longitudinal to inclined shear failure that demonstrates an escalation in rock plasticity. In the event the confining pressure reaches 30 MPa, there remain neighborhood shear https://trevorbyqjy.wikiinside.com/4124949/not_known_facts_about_wellbore_stability_issues
