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) gathers 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 event whereby formation lithology and fluid content can be evaluated.
