Conclusions

We have proposed a processing flow suitable for cross-equalizing off-the-shelf migrated seismic datacubes for reservoir monitoring and tested the flow on two seismic surveys from the Gulf of Mexico. After cross-equalization, amplitudes may be compared more directly making 4-D interpretation easier. The flow consisted of four basic elements, each of which has a physical basis: spatial realignment, matched-filtering, amplitude balancing, and warping.
