Abstract: Identifying Stratigraphy and Fluids Using Spectral Decomposition: The Current State of the Art

By

Various wavelet transform techniques have resulted in spectral decomposition with improved vertical resolution and more accurate frequency spectra. Some of these algorithms are matching pursuit of various kinds, the continuous wavelet transform, and various optimization methods. Spectral decomposition has been used successfully in both direct hydrocarbon indication and stratigraphic interpretation. The next major hurdle to overcome in the interpretation of spectrally decomposed data is separating fluid and stratigraphic effects. Experience has shown that integrated analysis of spectral decomposition with other attributes (such as AVO) combined with stratigraphic interpretations yields the best results.
