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

摘要

method of seismic processing in which to determine the transit time of acoustic wave between a seismic source and a point in the subsurface, we solve the eikonal equation.characterized in that in order to solve the eikonal equation, we implement an extrapolation on the treatment of variable speed.which is equal to the ratio of the distance between the seismic source and the point of ground on the propagation time between the source and the point.
