In this study, two criteria are employed: the Mohr–Coulomb (M–C) criterion as well as multi-weak-plane power criterion for shale formations. They're utilized to perform research and accomplish the optimization with the failure conditions for shale–sandstone interbedded reservoirs. The Patchy Plane of Weakness criterion extends Jaeger’s single weak plane product https://nybookmark.com/story23489435/the-5-second-trick-for-wellbore-stability-analysis
