Abstract: A seismic data acquisition system includes a streamer spread including plural streamers that extend along an inline direction X; a set of front sources that are positioned ahead of the streamer spread along the inline direction X; and a set of top sources that are positioned on top of the streamer spread, along a horizontal direction that is perpendicular to the inline direction X. A characteristic of the set of front sources is different from a characteristic of the set of top sources, and bins corresponding to collected seismic data from each source set are interleaved.

Abstract: A method for steering a vessel (6) towing a streamer (7) or a streamer spread. The method comprises acquiring or determining a desired trajectory (PPL) for at least one point (CS7) of the streamer (7) or of the streamer spread; acquiring or determining water current values; modelling a plurality of trajectories for the streamer (7) or the streamer spread according to a plurality of given courses for the vessel and said water current values; determining a target course (T6) for the vessel (6) in function of said plurality of modelled trajectories for the streamer (7) or the streamer spread, and in function of said desired trajectory (PPL) of said at least one point (CS7) of the streamer (7) or of the streamer spread, so that the position (TCS7) of said at least one point (CS7) of the streamer (7) or of the streamer spread, that results from the determined target course (T6) of the vessel (6), follows said desired trajectory (PPL) or follows a trajectory that is included in a predefined width corridor that contains said desired trajectory (PPL); and steering the vessel (6) according to the determined target course (T6). It is also proposed a related computer program, navigation system and method for seismic data acquisition.

Abstract: A marine seismic data acquisition system includes a streamer spread including plural streamers; a first set of front sources configured to generate seismic waves; a streamer vessel towing the streamer spread and the first set of the front sources, in front of the streamer spread along an inline direction X; a second set of top sources configured to generate additional seismic waves; and first and second source vessels towing the second set of top sources directly above or below the streamer spread. A number NT of the top sources is larger than a number NF of the front sources.
