Spectral decomposition — A case study from the Vienna Basin

Abstract

Summary Spectral decomposition has the potential to look beyond conventional seismic data. Therefore, it is a useful tool to generate a seismic attribute, which serves the interpreter as an additional layer of information in his daily work. The general aim of this study is to illustrate potential applications for spectral decomposition allowing geologists to incorporate results of this technique into their interpretations. Two Miocene horizons of interest in the 3-D seismic data set “Vienna Basin” are investigated using spectral decomposition. This approach successfully reveals features beyond seismic resolution. Sedimentary structures that are not apparent in the conventional seismic data become visible and relative thicknesses within sedimentary units can be mapped in the spectrally decomposed data.
