Hydrophone moving-related moveout correction for marine streamer data
【Abstract】Hydrophones move with the streamers in acquisition of marine seismic data. Such movement causes travel time errors, which has a negative impact on subsequent data processing and data matching for time-lapse seismic survey. To correct the moveout caused by hydrophone moving, we use offset, vessel speed, and stacking velocity to calculate time-varying travel time errors, which is proportional to offset and vessel speed but inversely proportional to the square of stacking velocity. Field data processing shows that after hydrophone moving-related moveout correction, residual moveout in common midpoint (CMP) gathers after automatic normal moveout (NMO) correction is further reduced, and velocity spectra become more focused. This lays the data foundation for subsequent processing.
