Automated spectral recomposition with application in stratigraphic interpretation |
Applying spectral recomposition, we have been able to better visualize seismic images in both cross sections and stratal slices. This technique has improved the interpreter's ability to image the various elements of the depositional system in extracted stratal slices. Spectral recomposition can also be used in forward modeling, in studying how different frequency components attenuate in the subsurface, newand in estimating thin-bed thicknesses using tuning frequencies. It provides a robust and phase-independent approach to seismic thickness estimation. Compared with conventional methods involving adjacent peaks and troughs picking, spectral recomposition requires only peak-frequency and amplitude estimation.
