Analytical model for studying the effect of weak bedding plane on wellbore stability [PDF]
International Journal of Mining and Geo-Engineering, 2023 Optimum mud weight estimation in wellbore is one of the most important steps to prevent instability. In wellbore stability studies, media (rock) is usually assumed to be isotropic but errors occur when weak bedding planes cause the rocks to be ...
