In this examine, two conditions happen to be used: the Mohr–Coulomb (M–C) criterion as well as the multi-weak-airplane strength criterion for shale formations. These are utilized to conduct exploration and achieve the optimization with the failure conditions for shale–sandstone interbedded reservoirs. Lamellar shale oil reservoirs develop millimeter-to-centimeter-scale siltstone and https://drillingfluid23107.eqnextwiki.com/6030664/everything_about_wellbore_stability_in_drilling
