It is well known among the seismic data processing community that the demands of reservoir characterization are far more rigorous than those of structural interpretation. Further, the undesired prestack seismic phenomena that need to be diminished or removed prior to reservoir characterization are also well known. The objective of this paper is to quantify the advantages of performing prestack data conditioning prior to reservoir characterization. Three specific seismic properties that will be addressed are: (1) signal-to-noise ratio (SNR), (2) offset-dependent frequency loss, and (3) gather alignment.
