Seismic data processing for AVO requires that certain steps be applied to common depth point (CDP) gathers (the individual traces prior to stacking). Areas of importance include (1) generalized [[amplitude correction]]s, (2) [[signal to noise ratio]] improvement, (3) robust [[Basic seismic processing#Deconvolution|deconvolution]], and (4) [[prestack migration]] prior to AVO analysis in structurally complex areas.
