Conclusions

We present an application of the WEMVA methodology to diffracted seismic data. Diffractions carry a substantial amount of velocity information which is largely ignored by the current MVA techniques. We show that diffractions can be used for accurate migration velocity analysis using the WEMVA methodology.

In the current form, the limitations of this method are identical to those of WEMVA, and are mainly related to the Born approximation assumed by the method which requires small perturbations. Further extensions are possible, but they remain subject to future research.
