As the confining strain improves, 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 force reaches thirty MPa, there are still community shear microcracks across https://well-control-in-drilling35431.ourabilitywiki.com/10876844/wellbore_stability_analysis_options
