Deconvolution in the radial trace domain

David C. Henley

ABSTRACT

The radial trace (R-T) domain has been shown to be useful for coherent noise attenuation and other seismic wavefield separation operations because of the particular geometric distortion produced by the R-T transform. The same distortion also means that the R-T domain is better suited for deconvolution than the X-T domain, because R-T raypaths more nearly satisfy the assumptions of the standard convolutional model. A comparison between deconvolution results computed in the X-T domain and those computed in the R-T domain for the same Blackfoot shot gather highlights some of the expected advantages of R-T domain deconvolution.
