Abstract
Abstract: Identifying Stratigraphy and Fluids Using Spectral Decomposition:
The Current State of the Art
By
University of Oklahoma
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.
