Conclusions and Future Work

Multi-scale PEF-based interpolation in both the cmp-absolute offset and source-receiver coordinates appear to yield acceptable results, although the cmp-absolute offset result is noticeably better. Using CMP-absolute offset coordinates has the benefit of being a smaller space to operate in. However, by using source-receiver coordinates, an interpolation scheme with two 2-D PEFs could be used, which would almost exactly match the distribution of the data compared to the random-sampling assumption made with the multi-scale approach. This would be substantially less expensive as no rescaling would be necessary.

The two most pressing future directions for this work are the applicability of these methods to 3D prestack data, and the effect of the different interpolations on the final migrated image.
