Wellbore stability analysis of layered shale based on the modified Mogi–Coulomb criterion
Borehole instability was frequently encountered during shale gas drilling. Most conventional models are not applicable to layered formation's wellbore stability analysis on account of anisotropic strength characteristic. In this study, an empirical equation for predicting anisotropic strength w...
