Seismic surveying techniques with illumination areas identifiable from primary and higher-order reflections

摘要

Techniques are disclosed relating to determining or executing a survey pattern for a marine seismic survey vessel. The survey pattern may be determined based on a determined subsurface illumination area. The subsurface illumination area may be identifiable from primary reflections and higher-order reflections detected by sensors disposed in a sensor streamer configuration that may be towed behind the survey vessel. The sensor streamer configuration may include a plurality of streamers. 140c 10 0 140a 140b 220- 202
