In this study, two criteria are already utilized: the Mohr–Coulomb (M–C) criterion plus the multi-weak-aircraft strength criterion for shale formations. They're utilized to perform investigation and reach the optimization of your failure standards for shale–sandstone interbedded reservoirs. As illustrated in Figure 9, in the event the rock’s elastic mechanical https://medium.com/@vertechs/revolutionizing-well-control-in-high-pressure-high-temperature-gas-drilling-environments-c212cb28aedd
