Seismic data acquisition with varying distance between seismic vessels

Abstract:

A method for acquiring seismic data comprises operating a seismic vessel towing at least one of a seismic streamer with a plurality of seismic sensors and a seismic source. The inline distance between the vessel and one or more other vessels is adjusted according to a predefined function, where the seismic vessels travel along offset seismic acquisition lines, by increasing and reducing the in-line distance during the acquisition of the seismic data.
