  • Patent number: 9684089
    Abstract: A method comprises obtaining vertical seismic profile (VSP) data using seismic sources positioned at corresponding shot locations at desired offsets from seismic receivers positioned in a borehole drilled through a formation. The method further comprises receiving seismic waves emanating from the seismic sources, processing the VSP data to determine vertical slowness of the formation, and analyzing an azimuthal anisotropy of the formation. This is performed by calculating modified total slowness of the formation using the vertical slowness and vertical polarization angle, calculating and applying a polar anisotropy correction to the modified total slowness to obtain a corrected value of the modified total slowness, and normalizing the corrected modified total slowness to a desired polarization angle.
