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: A method of seismic surveying A method of seismic surveying comprises the step of acquiring imaging seismic data relating to an underlying geological structure at a survey location and simultaneously, or substantially simultaneously, acquiring statics seismic data relating to the near-surface (5) at the survey location. The method may use an imaging source (12) to acquire the imaging seismic data and a separate statics source (13,13′) to acquire the statics seismic data. Alternatively only an imaging source (12) may be used, and the statics seismic data may be obtained from surface waves, airwaves or ground-roll waves that are generated by the imaging source and that have hitherto been regarded only as unwanted noise.
