Abstract:
A method of seismic surveying using a plurality of vibratory seismic sources, the method including the steps of:deploying at least one seismic sensor; deploying a plurality of vibratory seismic sources at different source points; simultaneously actuating said seismic sources; acquiring seismic data attributable to said seismic sources using said seismic sensor; redeploying said seismic sources so that at least one of them is positioned at a source point previously occupied by another of them; simultaneously actuating said redeployed seismic sources; acquiring seismic data attributable to said redeployed seismic sources using said seismic source; decomposing said acquired seismic data into components attributable to each said seismic source; and stacking together components attributable to seismic sources located at a common source point.
