The reliability of the kurtosis-based wavelet estimation
Yungui Xu, Pierre D. Thore, Sebastien Duchenne · 2012
We present an analysis of the Kurtosis method used to estimate the phase of the wavelet without well log information. The kurtosis is a high order statistics which preserves the phase information. This paper aims to test the reliability of the Kurtosis method based on synthetic and real seismic data. We have addressed in our tests a number of factors (e.g. reflectivity character, seismic frequency bandwidth and signal-to-noise ratio) that potentially affect the final phase estimate. Our observations on the real data examples show that the phase estimated by this technique is influenced by the geology.
