METHOD FOR REGULARIZING OFFSET DISTRIBUTION IN TOWED SEISMIC STREAMER DATA

摘要

SEISMIC DATA FROM TOWED MARINE STREAMERS ARE SORTED INTO TWO-DIMENSIONAL COMMON MIDPOINT GATHERS OF TRACES (51). THE GATHERED TRACES ARE ORDERED BY OFFSET (52). THE OFFSET DISTRIBUTION OF THE ORDERED TRACES IS REGULARIZED (53). THE SOURCE AND RECEIVER COORDINATES OF THE REGULARIZED TRACES ARE ADJUSTED TO REFLECT THE REGULARIZING (54).
