Wellbore stability model in shale formation under the synergistic effect of stress unloading-hydration
According to the transversely isotropic theory and weak plane criterion, and considering the mechanical damages due to stress unloading and hydration during drilling, a shale wellbore stability model with the influence of stress unloading and hydration was established using triaxial test and shear t...
