Abstract

Summary

Much current interest in the field of broadband marine seismic is towards employing processing solutions to attenuate the effect of the sea surface ghost. Whilst focus is towards application in the pre-stack domain, our development of a 1-D based post-stack broadband processing workflow has shown it to be a feasible technique for achieving broader bandwidth data. Such a method allows a simple and efficient resolution improvement, particularly for legacy datasets, where pre-stack data is not available. Here we show examples of post-stack broadband processing to full stack data and discuss the benefits and limitations of broadband processing in the post-stack domain.
