With this research, two requirements are used: the Mohr–Coulomb (M–C) criterion as well as the multi-weak-airplane toughness criterion for shale formations. These are definitely utilized to conduct investigation and realize the optimization of your failure standards for shale–sandstone interbedded reservoirs. Mechanical screening serves being a foundational phase in figuring https://vertechs21.wordpress.com/2025/12/10/mastering-the-depths-how-vertechs-is-redefining-well-control-for-a-new-era-of-energy-security/
