Abstract：In current marine seismic data processing,acquisition footprints caused by energy variations are difficult to be suppressed effectively,severely impacting the signal-to-noise ratio and resolution of target areas.This paper focused on energy-induced acquisition footprints and developed a novel acquisition footprint attenuation technology based on the Kriging algorithm.The core idea of this method is to apply the Kriging algorithm to statistically analyze the spatial correlation variations in seismic data volumes,thereby deriving a coefficient volume for removing acquisition footprints and achieving their suppression.The key innovation lies in modeling the regionalized seismic data as a combination of acquisition footprint noise factors and effective reflection signals.Each acquisition footprint factor of the data volume corresponds to a specific variogram,and the distinction between acquisition footprints and effective reflection signals in the variogram domain enables the prediction and attenuation of footprints.Application results in marine seismic data processing demonstrate that this fully data-driven method outperforms traditional approaches in footprint attenuation while better preserving effective reflections.It provides a new solution for acquisition footprint attenuation and holds significant potential for broader application.
