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.
Procédé de traitement sismique dans lequel pour déterminer les temps de parcours d'une onde acoustique entre une source sismique et un point du sous-sol, on résolve l'équation eikonal, caractérisé en ce que pour résoudre l'équation eikonal, on met en oeuvre un traitement d'extrapolation sur la variable célérité, laquelle est égale au rapport de la distance entre la source sismique et le point du sous-sol sur le temps de propagation entre ladite source et ledit point.
