Abstract

Summary

We propose a partial time demigration method for enhancing prestack data quality. It is based on a single square root equation in terms of midpoint displacement, half-offset and migration velocity. By applying the partial time migration followed by subsequent new partial time demigration, the quality of original data can be improved. These prestack data can be used as input for improved conventional seismic processing, and can results in better images. The application to a simple synthetic data set as well as to a marine field data set demonstrates improved images with better signal-to-noise (S/N) ratio. The results show that amongst others, our method has potential for prestack data regularisation.
