Offset Footprint Analysis for Selecting Candidate Lines for Seismic Survey

摘要

An analysis is proved to determine a candidate line for at least one vessel to traverse in a 3D seismic survey to achieve desired coverage either along a planned line or a new infill line. The analysis can also be used in a 4-D survey to determine the coverage of a candidate line relative to the baseline survey previously conducted. The analysis determines a coverage footprint of the common midpoint lines, at given offsets, so the user or automated system can select a candidate line to achieve the best coverage.
