Deghosting of High Resolution Marine Seismic Data by Adaptive Filtering Algorithm

Effective deghosting algorithm of marine data can significanlty improve obtained information by removing notch frequencies from the recorded data.

We propose an efficient pre-stack deghosting algorithm, based on adaptive filtering. We demonstrate on real data, acquired with different sources, that developed algorithm can successfully remove ghost reflection from data and fill in notch frequencies in the recorded spectrum. Our algorithm can be applied both on single channel and multichannel high resolution marine seismic data.
