Abstract:
1. A method of acquiring marine seismic data using an acoustic source to generate an acoustic signal, a portion of which is reflected at one or more subsurface formation interfaces as a seismic signal, the method comprising: a) sailing a surface vessel along a sinusoidal sail line which lies over a survey area while towing a seismic streamer, the sinusoidal sail line having a configuration defined by an amplitude and a wavelength, the streamer including a plurality of hydrophones for receiving the reflected portion of the acoustic signal, wherein the streamer follows the configuration of the sinusoidal sail line while seismic data is acquired, and the streamer has a length at least equal to the distance travelled by the surface vessel as it sails along one full wavelength of the configuration as measured along the sinusoidal sail line.
