In general, we wish to interpret the most broadband data possible. However, do not always provide best insight for seismic attribute analysis. Obviously, spectral bands contaminated by noise should be eliminated. tuning gives rise with higher signal-to-noise ratios. To quantify geologic discontinuities in different scales, combined decomposition and coherence. Using decomposition, amplitudes corresponding a given scale discontinuity, as well some subtle features, which would otherwise buried within response, can extracted. We applied this workflow 3D land volume acquired over Tarim Basin, Northwest China, where karst forms principle reservoirs. found that channels are better illuminated around 18 Hz, while were delineated 25 Hz.
