The procedure of 3D seismic diffraction imaging for the depth structure followed by calculation of the diffraction attributes is considered. The algorithm is based on asymmetric summation of seismic data and makes it possible to identify three characteristics of the medium: the structural diffraction attribute, the point diffraction attribute, and the structural diffraction azimuth. These attributes allow one to distinguish between the fracture and cavernous zones and to determine the orientation of fractures. The practical evaluation of the approach is presented on real seismic data.
