In this study, two conditions happen to be used: the Mohr–Coulomb (M–C) criterion as well as multi-weak-aircraft strength criterion for shale formations. These are accustomed to perform investigation and obtain the optimization on the failure criteria for shale–sandstone interbedded reservoirs. Mechanical testing serves as a foundational step in analyzing https://lukaskbpcy.wikimidpoint.com/7349437/an_unbiased_view_of_shale_wellbore_stability
