Abstract:
1. A computer implemented method of processing a group of spatially related seismic data traces, comprising: defining seismic data windows extending over selected portions of said group of spatially related seismic data traces; generating a frequency spectrum of the seismic data within each successively selected windows of said seismic data traces by applying a transform to said successively selected windows having poles on a unit z-circle, where z is the z-transform; determining the frequency having the greatest amplitude within the frequency spectrum of the seismic data within each said successively selected windows; calculating kurtosis of each said frequency spectrum; determining if the kurtosis of each said frequency spectrum exceeds a selected value of kurtosis; utilizing said determined frequencies having the greatest amplitude within each frequency spectrum having a kurtosis value which exceeds said selected value of kurtosis to generate a seismic display in which horizontal dimension represents distance and vertical dimension represents time, wherein the seismic display represents calculated bed thickness, and utilizing said seismic display to determine the presence of thin beds.
