Seismic time-lapse image registration using amplitude-adjusted plane-wave destruction

Discussion and Conclusions

The proposed amplitude-adjusted plane-wave destruction algorithm provides high resolution scaling and vertical shifting functions to be computed between time-lapse seismic images. In seismic image registration, vertical shifts are sometimes insufficent for matching the images. Lateral shifts may be required as well (Hale, 2009). In our future work, we will adapt the algorithm to measuring multidimensional shifts by incorporating amplitude-adjustment into omnidirectional plane-wave destruction (Chen et al., 2013b).

The proposed algorithm utilizes a modification of plane-wave destruction filters to acquire high-resolution shifting and scaling functions between monitor images and a base image. Plane-wave destruction is particularly effective for measuring small shifts. When shifts are small, amplitude-adjusted plane-wave destruction can be used as a standalone algorithm to efficiently measure shifting and scaling functions between seismic images. When shifts are large, the proposed algorithm can be used to refine shift predictions from other registration algorithms. Separating scaling and shifting allows local shifts to be measured more precisely. The proposed algorithm has immediate applications to processing data from time-lapse seismic monitoring experiments.
