It has been found that, rather than merely recording raw data on the seismic vessel for processing on shore, the performance of certain processing on the vessel at a particular time addresses the problems. Specifically, performing pre-stack time migration on raw data as it is being recorded on a seismic ship provides the information needed for quality control of the acquisition process, as well as providing a starting point for velocity analysis in preparation for later depth migration. |
