... elastic medium, the magnitude of the in-plane far-field principal stresses ( 1 , 2 ) and their orientation ( ) can be uniquely determined. However, the Kirsch Solution has limitations, since the two-dimensionality is applicable only for conditions of plane strain or plane stress; and in reality...

... distribution model and weak plane strength criterion have been used to establish the wellbore stability model, which considers the influence of weak plane and chemical effect. Investigation on influence factors of collapse pressure is conducted through the established model. The results show that the existence...

... in shales for both wellbore stability analysis and stress determination requires the consideration of an appropriate material model accounting for strength anisotropy in the case of laminated formations. Common failure patterns such as strain localisation or buckling in the presence of bedding planes cannot...
