Abstract
The invention relates to an arrangement for seismic streamers used in the acquisition of seismic data in a marine environment where the spacing between each adjacent pair of streamers is not all the same. Some streamer spacings and/or receiver spacings are larger and some are smaller to provide a higher quality wavefield reconstruction when covering a larger total area or for a similar total area of seismic data acquisition while providing a wavefield that is optimally sampled by the receivers so that the wavefield reconstruction is suitable for subsurface imaging needs.
