Abstract:
1. A method for processing two seismic data cubes corresponding to a same subsurface zone, and respectively acquired by means of receivers at the ocean bottom and by means of surface receivers, said data cubes having amplitude or attribute values related to a plurality of points of said zone and at least one given time, wherein each data cube may be broken down into two component cubes, a noise cube and a common component cube, wherein said common component cube is determined as an estimate of a common component part of said seismic data cubes corresponding respectively to one and to the other of these two acquisition modes, said estimate of said common component being defined as the coherent or invariant part of said two seismic data cubes, the coherent or invariant part representing the redundant geological information of at least two of the seismic data cubes corresponding respectively to one and to the other of these two acquisition modes.
