During this analyze, two conditions are actually used: the Mohr–Coulomb (M–C) criterion plus the multi-weak-plane toughness criterion for shale formations. They are utilized to perform investigate and realize the optimization from the failure standards for shale–sandstone interbedded reservoirs. As illustrated in Determine 9, once the rock’s elastic mechanical parameters https://netwebdirectory.com/listings13606517/wellbore-stability-in-drilling-secrets
