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.

主权项

1. A method, comprising:
towing a plurality of sensor streamers behind a survey vessel; gathering, based on data received at sensors along the plurality of sensor streamers, information corresponding to primary reflections and information corresponding to higher-order reflections; navigating the survey vessel in a survey pattern, wherein said navigating is based on a subsurface illumination area identifiable from the information corresponding to primary reflections and the information corresponding to higher-order reflections.
