Abstract: Methods and systems for marine survey acquisition are disclosed. In one embodiment, a method is provided that may deploy a marine seismic spread that includes a first seismic source, a second seismic source and a streamer with a receiver. The second source may be disposed at a distance from the first seismic source in an inline direction. The distance may be selected to produce one or more pairs of shot points during a seismic survey. The shot points within a pair may be disposed within a range that is used to calculate a pressure source gradient between the shot points within the pair. The method may shoot the first seismic source and the second seismic source substantially simultaneously. The method may record seismic data associated with shooting the first seismic source and the second seismic source. The method may calculate the pressure source gradient for respective pairs of shot points.

Abstract: A technique for acquiring wide azimuth seismic data using simultaneous shooting is presented in which a plurality of seismic sources are positioned to achieve a desired crossline sampling as a function of the number of passes. This is accomplished by “interleaving” sources as deployed in the spread, as positioned in multiple passes, or some combination of these things, to achieve an effective shotline interval during acquisition or an effective crossline sampling less than their crossline source separation.

Abstract: Methods and systems for efficiently acquiring towed streamer marine seismic data are described. One method and system comprises positioning a plurality of source-only tow vessels and one or more source-streamer tow vessels to acquire a wide- and/or full-azimuth seismic survey without need for the spread to repeat a path once traversed. Another method and system allows surveying a sub-sea geologic feature using a marine seismic spread, the spread smartly negotiating at least one turn during the surveying, and shooting and recording during the turn. This abstract is provided to comply with the rules requiring an abstract, allowing a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
