Paper Summary
Using attributes enhances the QC of seismic data processing. These attributes can be derived in a manner that captures the characteristics of particular processing steps. The use of process specific QC attributes generated for two key stages in pre-migration flows, deblending and deghosting, is demonstrated over a 3D survey, acquired offshore Nigeria. A deblending attribute based on amplitude continuity reveals a variation in the process performance with varying water depth. Two attributes are used to QC source and receiver side deghosting, one based on wavelet width and another expressing frequency content as an RGB display. Both highlight deficiencies in the deghosting process due to uncertainties in cable depth headers. These attributes capture aspects of the data processing not apparent from visual inspection of the data alone.
