With this research, two conditions happen to be employed: the Mohr–Coulomb (M–C) criterion as well as the multi-weak-airplane toughness criterion for shale formations. These are typically accustomed to conduct exploration and attain the optimization on the failure standards for shale–sandstone interbedded reservoirs.
