Spectral Decomposition For Seismic Interpretation Patent 001 Download Seismic interpretation has two fundamental disciplines at its core: seismic geomorphology and seismic stratigraphy. spectral decomposition unravels the seismic signal into its constituent frequencies. this allows the interpreter to see amplitude and phase tuned to specific wavelengths. In this study, we demonstrate that the interpretability of seismic data can be enhanced with the use of spectral phase components derived during spectral decomposition. The main objective of stratigraphic interpretation is the determination of the types of stratigraphic features appearing on seismic sections. typical examples of such features are: facies changes, sand lenses, reefs, and unconformities. Techniques of seismic calibration, horizon correlation, preparing seismic maps, and velocity modelling and depth conversion are elaborated with examples and illustrations.

Techniques of seismic calibration, horizon correlation, preparing seismic maps, and velocity modelling and depth conversion are elaborated with examples and illustrations. Topics covered in this book include basic structural interpretation and map making; the use of 3 d visualisation methods; interpretation of seismic amplitudes, including their relation to rock and fluid properties; and the generation and use of avo and acoustic impedance datasets. In figure 10, a comparative display of results of spectral decomposition technique by dft and its extension, the cepstral decomposition technique by cct, and their resolution capabilities are examined. Apart from attributes converting seismic data from time domain to frequency domain, using spectral decomposition, has also worked effectively in identifying thin beds and direct hydrocarbon indicators. Spectral decomposition algorithms (such as dft, st, cwt, tfcwt, matching pursuit, etc.) are applied to seismic reflection data to break down the seismic signal into its frequency components (see figure 1).
