In this research, two requirements are already utilized: the Mohr–Coulomb (M–C) criterion as well as multi-weak-aircraft energy criterion for shale formations. These are used to conduct study and obtain the optimization with the failure conditions for shale–sandstone interbedded reservoirs. Lamellar shale oil reservoirs produce millimeter-to-centimeter-scale siltstone and mud shale https://fluidrheology77553.empirewiki.com/10005831/top_latest_five_wellbore_stability_urban_news
