What is it about?
In this paper, wavelet-based cepstrum decomposition is proposed as a valid technology for enhancing geophysical responses in specific frequency bands, in the same way as traditional spectrum decomposition methods do.

Why is it important?
Wavelet-based cepstrum decomposition offers an easier way for using the cepstrum amplitude anomaly related to the quefrency information for reservoir characterization and hydrocarbon detection compared with conventional spectral decomposition methods, and it provides a new field of processing and interpreting seismic reflection data.
Perspectives
In terms of how to use cepstrum analysis for exploration seismology, the wavelet-based cepstrum decomposition is proposed and discussed in this paper.By comparison of the common quefrency section extracted by wavelet-based cepstrum decomposition with the common frequency section extracted by traditional spectrum decomposition methods, we demonstrate the effectiveness of wavelet-based cepstrum decomposition.Further research, particularly if applied to other datasets, will contribute to a better understanding of the advantages and the practical restrictions of this method.
