Conclusion

We image steeply dipping reflectors in VTI media by anisotropic plane-wave migration in tilted coordinates. We decompose source and receiver wavefields into plane waves and extrapolate the wavefields with an implicit isotropic operator followed by an explicit anisotropic correction in tilted coordinates. We apply our method to a synthetic dataset. The results show that our method can handle overturned waves and accurately image steeply dipping reflectors in VTI media. We generate angle-domain CIGs by cross-correlation.
