During this analyze, two conditions happen to be used: the Mohr–Coulomb (M–C) criterion as well as multi-weak-plane power criterion for shale formations. These are typically utilized to perform analysis and achieve the optimization of the failure conditions for shale–sandstone interbedded reservoirs. Lamellar shale oil reservoirs build millimeter-to-centimeter-scale siltstone and Successfully Submitted (Awaiting Approval)
