Abstract: Embodiments provide for a method that utilizes the azimuthally spaced receivers of a sonic logging tool.

For the incident P-waves from the monopole source, phase arrival times for the azimuthal receivers are compensated for stacking using properties of wave propagation in the borehole, and for the incident SH-waves from the dipole source, signs of waveforms for the receivers are changed for specified azimuths.
