Cross-dipole acoustic logging traditionally uses to study the anisotropy of the formation acoustic properties. The method is based on comparing the velocities of fast and slow shear waves and calculating the anisotropy coefficient. In the anisotropic formation, the flexural wave is splitting into two modes. The amplitude of cross-components XY and YX will be non-zero and significant in the anisotropic zones of the formation. There are several approaches to assessing the presence of anisotropy in a formation. As a ...
