Claim 18:
19. A system for formation evaluation, comprising:
a seismic source to emit a radiated seismic P-waves;
a plurality of multicomponent seismic receivers for detecting and recording a multicomponent seismic data set generated by the radiated seismic P-waves; and
a seismic processor configured to:
determine a PP stacked time-domain seismic image and a PS stacked time-domain seismic image from the multicomponent seismic data set;
transform a recording-time axis of at least one of the PP stacked time-domain seismic image and the PS stacked time-domain seismic image to produce a pair of coarsely-registered PP and PS seismic images;
filter at least one of the pair of coarsely-registered PP and PS seismic images to produce a pair of spectrally-matched PP and PS seismic images; and
dynamically warp at least one of the pair of spectrally-matched PP and PS seismic images to produce a pair of fully-registered PP and PS seismic images.
