ABSTRACT A method is provided for enhancing processing and evaluating seismic data. More particularly, a novel method is described for enhancing and evaluating common depth point seismic data. Common depth point (CDP) gath- ers of seismic signals are processed to suppress random noise and coherent noise and to enhance primary reflection events while preserving geologically-induced amplitude variations as a function of range for the primary reflection events. The processed CDP gathers of seismic signals can then be processed to obtain attributes descriptive of amplitude variations as a function of range for the selected primary reflection events whereby forma- tion lithology and fluid content can be evaluated.
