During this study, two requirements are utilized: the Mohr–Coulomb (M–C) criterion and the multi-weak-airplane toughness criterion for shale formations. They're accustomed to conduct analysis and reach the optimization of the failure criteria for shale–sandstone interbedded reservoirs. Lamellar shale oil reservoirs produce millimeter-to-centimeter-scale siltstone and mud shale complex... https://tryhere11086.wikilowdown.com/7918180/the_2_minute_rule_for_wellbore_stability_issues
