Fracture pressure model for inclined wells in layered formations with anisotropic rock strengths

Fracture pressure is one of the most important foundations of drilling engineering, and the anisotropy of tensile strength is also a distinct feature of layered formations, but the anisotropy of tensile strength has seldom received attention in the analysis of fracture pressure. In the present paper, a novel fracture pressure model was proposed for inclined wells in layered formations with anisotropic rock strengths. Firstly, the characteristics...
