Taking Seismic Acquisition Artifacts Beyond Mitigation

Seismic acquisition footprint is an irritating noise type on the seismic data. This footprint noise is the dominated noise on the seismic stacked data; however, the common practice nowadays is removing them by filtering using 3D FKxKy frequency slice notch filter in pre-stack stage on OVT (offset vector tile) minimal data set in the orthogonal acquisition geometry in particular. Any acquisition footprint noise remnants will definitely hinder the accurate fault and fractures lineament seismic interpretation, since any discontinuities in the seismic might be treated as fractures or faults. Elimination, attenuation, or mitigation of this noise is some sort of compromise in this noise removal. Taking acquisition footprint beyond mitigation to be fully suppressed by applying alternative cascaded processing approach is the main goal of this study.
