A process of illumination
The reworking of previously analyzed seismic datasets or reprocessing has always played a significant part in the makeup of a seismic contractor's workload. The type of datasets being reworked runs the gamut from old onshore 2D analog data from central Asia through recently acquired marine 3D surveys from the Gulf of Mexico and the North Sea. This activity has always been an important revenue source for geophysical contractors, particularly when new acquisition activity is depressed. It is difficult to generalize what percentage of total processing revenues comes from reprocessing, as temporal and geographic variance is substantial. On average, it probably exceeds 50% of the total processing budgets in the industry. This paper describes why data is reprocessed, depth migration, regional context, reservoir characterization, remediation of infield processing, nonexclusive reprocessing, deepwater hazard surveys, and time-lapse 4D seismic.
