Conclusions

Building a velocity model accurate enough to remove FEAVO effects by prestack depth migration is an important problem which has not been solved satisfactorily until now. WEMVA, with a fitting goal adapted to the specific morphology of the anomalies, is a promising tool that will likely solve the problem. Work in this direction has proven that the iterative inversion is feasible: real data focusing effects are visible in the angle domain, the anomalies are preserved by waveform modeling, and the linearized downward continuation operator does not destroy the anomalies.
