SEISMIC SURVEYS WITH INCREASED SHOT POINT INTERVALS FOR FAR OFFSETS

Techniques are disclosed relating to configuring a marine seismic survey. In some embodiments, a vessel (210) may be coupled to one or more seismic sources (220) and one or more seismic streamers (250), and a second vessel (230) may be coupled to one or more far offset seismic sources (240). The near offset sources (220) may be configured to actuate according to a shot point interval; the far offset sources (240) may be configured to actuate according to a longer shot point interval. In some embodiments, the longer shot point interval may be a multiple of the near offset source shot point interval. Determining the first and second shot point intervals may be based in part on, for example, the wave frequencies of the far offset sources, the requirements of a full wave inversion process, or various configurational parameters of seismic surveys.
