Abstract
A method of processing seismic data using a seismic energy propagation model of the subsurface is disclosed. The method assigns seismic source, seismic receiver, and reflection point locations to the propagation model; identifies a plurality of alternative raypaths consistent with the propagation model that originate at said seismic source location, reflect at said reflection point location, and terminate at said seismic receiver location; selects a raypath from the plurality of alternative raypaths having a shortest ray length, and utilizes the selected raypath in subsequent seismic processing.
