S-wave and P-wave anisotropy at line tie. Reflectors with greatest azimuthal difference in P-wave AVO gradient (Z, MB) are found at tops of intervals with greatest S-wave anisotropy (Z-TN1, MB-DG4). Reflectors with little azimuthal difference in AVO gradient (TGR, TN1) are associated with intervals showing only background levels of S-wave anisotropy (TGR-Z, TN1-MB).
