With this study, two requirements are used: the Mohr–Coulomb (M–C) criterion as well as multi-weak-plane toughness criterion for shale formations. They're accustomed to carry out exploration and reach the optimization with the failure criteria for shale–sandstone interbedded reservoirs. Lamellar shale oil reservoirs produce millimeter-to-centimeter-scale siltstone and mud shale complexes waiting for link from Forum Profiles (11)
