Reconnaissance marine seismic surveys having reduced density of sail lines

Abstract:

Methods, systems, and apparatuses are disclosed for conducting reconnaissance marine seismic surveys. In one example method of acquiring a marine seismic survey, a plurality of streamers are towed behind an acquisition vessel, the plurality of streamers defining a swath. A source is towed behind the acquisition vessel, and at least one other source is towed outside of the swath of streamers.
