ABSTRACT:
A Method of measuring local similarities between seismic trace cubes (3D survey) obtained from a volume of an underground zone, corresponding to prestack data or to repeated seismic surveys (4D survey). For each point of the volume considered, the method comprises a) extracting, from each seismic trace cube, a volume neighborhood centered on a point, referred to as current point, and consisting of a set of seismic traces in limited number; b) applying an analysis technique referred to as (GPCA) allowing defining synthetic variables; and c) determining a coherence value from the synthetic extracted variables measuring the local similarity between the seismic trace cubes extracted from the volume neighborhood of the current point. The coherence value thus calculated is assigned to the current point. The coherence values of all of the current points form a coherence cube. An application is finer monitoring of the evolution with time of a reservoir under development.
