Abstract
A computing system and method for mitigating, in a first seismic survey, cross-talk generated by a second seismic survey. The method includes performing the first seismic survey with a first survey seismic source driven by a first survey pilot sweep, performing the second seismic survey with a second survey seismic source, simultaneously with the first seismic survey, recording with first survey seismic sensors (i) first survey seismic signals that originate from the first survey seismic source and (ii) second survey seismic signals that originate from the second survey seismic source, selecting another first survey pilot sweep, which has less cross-correlation noise with the second survey seismic signals than the first survey pilot sweep, and continuing the first seismic survey with the another first survey pilot sweep.
