METHOD FOR QUANTIFYING WATER COLUMN TIMING AND AMPLITUDE ANOMALIES IN A 3 DIMENSIONAL SEISMIC SURVEY

摘要

A method is disclosed for determining timing error between segments of a marine seismic survey (Fig. 2). The method includes picking arrival times of a water bottom reflection event in a plurality of seismic signals acquired in a plurality of seismic survey segments (16). A discontinuity in the picked arrival times is determined between at least two survey segments at locations corresponding to substantially the same water bottom reflection points (42-48). An amount of time adjustment is determined for at least one of the survey segments based on the discontinuity (52).
