A seismic cube is determined estimating the mathematical intersection of at least two seismic cubes corresponding to different instants of acquisition. The intersection is subtracted from one of the initial cubes. The differential cube so obtained is filtered. The estimated cube is subtracted from an initial cube. The differential cubes so obtained are filtered. Each of the seismic cubes is converted to the frequency domain, to obtain a real and an imaginary cube. The commonality is then calculated for the imaginary cubes. The two cubes so obtained are converted into the temporal domain, one being real and the other imaginary. |
