Using 2D Ring Arrays to Remove Back-Scattered Surface Noise from Land Seismic Data

Surface noise often dominates signal in land seismic acquisition by a large amount, perhaps 2x to 20x, which limits the usefulness of land seismic data, especially converted waves and possibly attributes. Much of this noise is also back-scattered. We propose an approach of reducing back-scattered surface noise by designing field acquisition to better sample the noise in X & Y so that it can be more easily removed in processing.
