Several time-frequency transform methods have been used for spectral decomposition of seismic data. Comparisons between methods have been largely qualitative with a focus on their relative time and frequency resolutions. Very little has been said about the fidelity of spectral decomposition results relative to the original data and the quantitative differences between methods. This paper provides some analysis of these issues as they relate to three decomposition methods.Link: Paper
We examine the use of a time-frequency transform based normal moveout (NMO) correction and its effects on normal moveout stretch distortion. Our analysis contributes to understanding the nature of normal moveout stretch, particularly in the time-frequency domain.Link: Abstract | Link: Poster

Applications of Matching Pursuit signal analysis methods have made significant inroads into use in seismic data analysis. In our review of the geophysical literature we found applications to migration, interpolation, spectral decomposition and others. Our review also indicated three areas where thorough understanding of practice, as it applies to spectral decomposition, is lacking and leads us to answer several questions.

Instantaneous attributes are commonly used in interpretation and in quantitative prediction of reservoir properties. Quantitative use of instantaneous attributes requires that they be free of systematic error. Our goal is to highlight algorithm improvements that are necessary for their quantitative use.Link: Abstract | Link: Poster
