Conclusions

We have demonstrated the potential of the wave equation based shot-profile migration developed by Artman and Shragge (2003) for imaging with the teleseismic wavefield using two synthetic datasets. In addition, preliminary images produced with the forward-scattered P-to-S mode correlate well with previous methodology. The images may be enhanced with better source wavefield modeling and wavefield interpolation prior to processing. Other improvements could be made by imaging each scatterig mode after multiple and/or primary suppression or simultaneously inverting the entire wavefield to solve for a single earth model defined by all scattering modes (e.g. simultaneous multiple and primary migration).
