Abstract

Summary

For land seismic surveys, source-generated energy propagating in the near-surface is often scattered due to topography variations and geological heterogeneity. Historical approaches to attenuate scattered energy have relied on relatively large, areal, source and receiver arrays in the field which have been time-consuming and expensive to deploy and often of limited effectiveness. In this abstract we ask the question - can complex scattered surface wave energy present in land surface seismic be adequately attenuated using only digital signal processing?

And answer with the demonstratation of a combination of three new processing techniques developed, to complement acquisition systems using point-sources and point-receivers, to effectively attenuate problematic scattered coherent noise that is typically low frequency and requiring explicit removal to support broadband full azimuth surveys.
