Vibroseis acquisition technique and system using dynamic source control

摘要

A technique includes during a seismic acquisition, selectively forming groups of at least one seismic source from a plurality of seismic sources as the seismic sources become available based at least in part on a minimum source spacing distance. The technique also includes selectively activating the groups. Each group responds to being activated by substantially simultaneously initiating a sweep for the seismic source(s) of the group. The technique further includes regulating a timing of the group activations based at least in part on a slip time and a minimum group spacing distance.
