Abstract
Method of processing a collection of seismic cubes corresponding to one and the same acquisition zone and to various moments of acquisition, characterized in that at least one seismic cube which is an estimate of the component common to at least two seismic cubes corresponding to different moments of acquisition is determined and this estimate of common component is subtracted from at least one of the two initial cubes.

Method of processing a collection of seismic cubes, each seismic cube corresponding to a gather of seismic traces in which each seismic trace is a time-dependent amplitude signal and is associated with a given position on the ground zone over which the acquisition has been carried out, the various seismic cubes corresponding to one and the same acquisition zone and to various moments of acquisition, characterized in that at least one seismic cube which is an estimate of the component common to at least two seismic cubes corresponding to different moments of acquisition is determined and this estimate of common component is subtracted from at least one of the two initial cubes.
