In this particular review, two conditions happen to be used: the Mohr–Coulomb (M–C) criterion and the multi-weak-plane strength criterion for shale formations. These are utilized to perform exploration and reach the optimization with the failure requirements for shale–sandstone interbedded reservoirs. Lamellar shale oil reservoirs acquire millimeter-to-centimeter-scale siltstone and mud waiting for link from Forum Profiles (11)
