Coherence based on spectral variance analysis - GeoScienceWorld
Coherence is a measure of similarity between waveforms or traces. The seismic waveform is a response of the seismic wavelet convolved with the geology of the subsurface. That seismic response changes in terms of amplitude, frequency, and phase, depending on the acoustic-impedance contrast and … See more There are a variety of coherence methods. A more detailed discussion of these methods can be found here. Among these are: See more The analysis window chosen can have a significant effect of the results. Longer windows tend to mix stratigraphy, which can complicate the … See more WebCoherency filtering is a tool used commonly in 2-D seismic processing to isolate desired events from noisy data. It assumes that phase‐coherent signal can be separated from background incoherent noise on the basis of coherency estimates, and coherent noise from coherent signal on the basis of different dips. It is achieved by searching for the … WebCoherence (Bahorich and Farmer, 1995) and Sobel-filter-based edge detectors (Luo et al., 1996) measured lateral changes in seismic waveforms and amplitude.
