Spectral Enhancement (Comparison of three spectral enhancement methods)

by Nick McAdle (ffA), Gaynor Paton (ffA)

Spectral enhancement is a technique for selectively boosting portions of the seismic signal with distinguishable frequency content. It is often applied to seismic data in order to boost the high frequency content of the data, which can be masked by underlying low frequency signal. The practical application is to improve the vertical resolution of events thereby improving interpretability.  Here we compare three different methods of spectral enhancement that are regularly applied to 3D post stack seismic data. We are particularly interested in the effectiveness of each technique in enhancing real signal in the data, as well as the efficiency of each process at this task.
