WebApr 10, 2024 · We assume that the borehole is inclined to the X-Y-Z far-field principal stress axes. The Cartesian coordinate system coincides with the principal axes of the in-situ far-field stress, which are designated as σ x, σ y, σ z. The borehole coordinate is defined by a local coordinate system x-y-z, with the borehole axes coinciding with the z-axis.
