  • Patent number: 6697737
    Abstract: Attributes of a seismic data set that are indicative of the quality of the seismic data are displayed in a quality control (QC) hypercube. The axes of the hypercube may be the source position, the source line, the receiver position and a processing step. In a pre-migration QC cube, two of the three axes of the cube are defined by the locations of seismic data. In a migrated QC cube, two of the three axes are defined by the migrated output bin position of processed seismic data. The third axis of the cube contains information about the quality of the data. The QC attributes may be simple amplitudes, or they may be attributes derived from the amplitudes of the seismic data, such as RMS values and/or spectral values. In a migrated QC cube, the attributes may include seismic velocity, seismic fold and distribution of source-receiver azimuths.
