<p>A method is described for obtaining a volumetric image of a geological structure (20) present in the subsoil. The method comprises the following phases: generating a plurality of seismic waves by means of a plurality of seismic sources (12); acquiring a plurality of signals or traces, obtained by processing the seismic waves reflected by the geological structure (20), for creating a seismic record or shot gather for the same activation position of each seismic source (12); migrating, through a numerical processing, each shot gather to create a respective partial volumetric image of the geological structure (20); summing the single partial volumetric images to obtain the overall volumetric image (I i ) of the geological structure (20).</p> |
