Claim:
1. A method, comprising: obtaining vertical seismic profile (VSP) data for a well using one or more seismic receivers positioned in a borehole drilled through a formation, the one or more seismic receivers receiving seismic waves emanating from seismic sources positioned at a corresponding one or more shot locations at desired offsets from the one or more seismic receivers; processing the VSP data to determine vertical slowness of the formation surrounding the borehole and to determine vertical polarization angles of the seismic waves received by the one or more seismic receivers; correcting and analyzing an azimuthal anisotropy of the formation by: estimating azimuthal anisotropy of the formation based on the corrected value of the modified total slowness; and outputting an anisotropy depth profile of the formation.
