Deblurring Seismic Images by Deconvolution

Abstract

Summary Deconvolution is routinely applied in seismic processing to enhance the resolution of migrated images. We present a deconvolution-based inverse scattering imaging condition for reverse time migration (RTM). While full multi-dimensional deconvolution is only achieved through expensive least-squares migration, we demonstrate that the 1D deconvolution imaging condition can be sufficient to provide considerable improvements to image resolution. We present a field data example that shows significant enhancement in quality of migrated images and angle gathers using 1D deconvolution imaging.
