A Method for Estimating the Azimuth of a Fast Shear Wave from the Acoustic Log

The estimation of the fast shear wave azimuth is the one of the main tasks of acoustic logging data processing in the anisotropic formation. There are several methods that allow such an assessment. In this paper, we propose a method for determining the direction of a fast and slow transverse wave, based on the rotation of wave patterns at a given angle and calculating their displacement relative to each other. This method can complement existing techniques or be used separately from them.
