ABSTRACT

A resonant multiple is defined as a multiple reflection that revisits the same subsurface location along coincident reflection raypaths. We have found that resonant first-order multiples can be migrated with either Kirchhoff or wave-equation migration methods to give images with approximately twice the spatial resolution compared with poststack primary-reflection images. We have developed a moveout-correction stacking method to enhance the signal-to-noise ratios of the resonant multiples for superresolution migration. The effectiveness of this procedure is validated by synthetic and field data tests.
