With this research, two standards are already employed: the Mohr–Coulomb (M–C) criterion and the multi-weak-plane energy criterion for shale formations. These are definitely accustomed to perform exploration and realize the optimization on the failure requirements for shale–sandstone interbedded reservoirs. As illustrated in Figure 9, once the rock’s elastic mechanical https://travisfbyao.hamachiwiki.com/2668323/about_wellbore_breakout_analysis
