Within this analyze, two conditions are actually utilized: the Mohr–Coulomb (M–C) criterion and the multi-weak-plane strength criterion for shale formations. They're utilized to carry out analysis and attain the optimization on the failure standards for shale–sandstone interbedded reservoirs. The Patchy Airplane of Weak spot criterion extends Jaeger’s single weak https://robustdirectory.com/listings1893984/wellbore-stability-issues-an-overview
