Abstract

Summary

The removal of source-generated coherent energy propagating in the near-surface continues to be a fundamental step in land surface seismic data processing and one of key importance for subsequent reservoir characterisation. Such noise overlays and obscures a significant portion, in time and space, of the reflection signal and requires effective removal to maximise the value delivered to the reservoir geologist, as well as the perceived value of onshore seismic itself. Common strategies for the attenuation of this complex coherent noise have historically included both acquisition and data processing techniques, with the former using large areal source and receiver arrays and the latter using aggressive velocity filtering, both providing limited effectiveness. We describe a new systematic, cascaded, approach for the progressive attenuation of both the complex direct-arrival and scattered surface wave energy prevalent in land seismic data.
