Conclusions and future work

The results in both the synthetic and field data examples show that this method works at capturing large inline features in the data. The field data example shows in particular that the PEF is insensitive to issues with the squared spectrum, amplitude scale and phase, which avoids the need for preprocessing involving amplitude scaling and deconvolution prior to cross-correlation.

The utility of this method in 3D is limited by the poor spatial distribution of sources, which has also been the case with passive interferometric methods. However, future acquisition methods may increase source density and aperture, which could in turn produce more useful pseudoprimaries in the crossline direction. Alternatively, this approach could be combined with moveout operators to produce data to add to the correlation.
