Seismic data processing methods to suppress the acquisition footprint

Abstract

Acquisition footprint refers to the artifacts in the seismic data acquisition. It is the imprint which is impressed on 3D seismic data by not quite suitable geometry. Footprint makes the attributes, such as amplitude, frequency, and phase change on time or depth slices. The paper analyses the effect of acquisition footprint on the seismic and geologic attributes with actual seismic data. The discussion focuses on the basic principle, application conditions, advantages and disadvantages of several seismic data processing methods, such as, bin equalization technology, pre‐stack data interpolation, and 3D post‐stack frequency‐wavenumber domain filter to suppress the acquisition footprint. Finally these methods' application results with the actual seismic data are shown, the goal is to find some effective approaches to suppress the acquisition footprint in seismic data processing.
