SEISMIC DATA ACQUISITION WITH VARYING RELATIVE DISTANCE BETWEEN MULTIPLE SEISMIC VESSELS.

摘要

The present invention generally relates to marine seismic prospecting, and in particular to seismic prospecting using multiple vessels. During acquisition of seismic data, a distance [D] between a first seismic vessel [110] and a second seismic vessel [120] may be adjusted according to a predefined function such that data is collected at a variety of offsets.
