Conclusion

Preliminary results from attribute versus coherence crossplots at the range of CMPs studied suggest that, for the case of maximum semblance coherence measurements, attribute values are more dispersed for lower coherence values and more localized for higher coherence values. For more definitive results, we need to do further work to improve the velocity coherence measures.

The next steps should comprise analysis of other regions of the flat reflector, use of additional coherence measurements (like the amount of residual moveout correction), and testing with a simpler data set. We also think it is important to investigate this problem using a synthetic model that allows more control over the data.
