Applications of the Trace Transform in Surface Wave Attenuation on Seismic Records

Abstract

A main target of seismic data processing is to remove the surface waves and improve the quality of seismic records. Here, we propose a Co-Core Trace (CCT ) transform filtering based on the Trace transform from image processing and apply it to seismic surface wave attenuation. The CCT transform is designed according to the distribution and propagation of the surface waves. In the CCT transform domain, the energies of surface waves are significantly enhanced and could be filtered out with a relative threshold, while the reflection events are saved due to the conspicuous disparity. Experiments on both synthetic model and field data demonstrate that the proposed algorithm performs well both in surface wave attenuation and reflected signal preservation, besides presenting advantages over some conventional methods.Index Terms-Seismic record processing, surface wave filter, the Co-Core Trace (CCT ) transform filtering, the Trace transform.

A Novel method for Delineating Thick and Thin Sub Surface layers of the Earth using Wavelet Local Maxima Lines

“…Limited lateral resolution: While seismic reflection surveys provide good lateral resolution along the survey line, lateral resolution decreases with depth . This limitation can be significant when trying to characterize features with lateral variations, such as thin stratigraphic layers or small-scale structures [11] .…”
