METHOD FOR SEISMIC PROCESSING AND IN PARTICULAR FOR THREE-DIMENSIONAL SEISMIC EXPLORATION USING SEISMIC DATA MIGRATION

摘要

The invention concerns a method for seismic processing which consists in solving the eikonal equation for determining the travel times of an acoustic wave between a seismic source and a point in the subsoil. The method is characterised in that to solve the eikonal equation it consists in using an extrapolation processing on the celerity variable, which is equal to the ratio of the distance between the seismic source and the point in the subsoil over the propagation time between said source and said point.
