Point and Edge Diffractions in Three Dimensions

Small geological objects – faults, fractures, karst, etc. – are presented by the diffracted component in the wavefield registered by seismic survey. Diffraction events analysis allows getting information about these objects. It this study we demonstrate how diffraction events behave in the migrated dip-angle domain. Using synthetic and real data we show that the event shape analysis makes it possible to detect a single diffraction point position, fractures direction and fault orientation.
