Several aspects of processing 3-C data to obtain anisotropy information from shear-wave splitting are demonstrated. This includes: analysis for unknown or uncertain field orientations of the receivers; a new method of splitting analysis which uses both radial and transverse component data to estimate the S1 direction, which is compared with a transverse only method; and some analysis of the difference between P-S1 and P-S2 imaging versus anisotropy-corrected “radial-prime” (R') imaging.
