Patent ID: 6912466

Claim:
A method for analyzing and displaying seismic graphical data, said method comprising the steps of: (a) selecting a model function for said analyzing; (b) determining a frequency of said seismic graphical data; (c) setting a frequency for said model function substantially equal to said frequency determined in step (b); (d) selecting a sample location from a plurality of sample locations within said seismic graphical data, and retrieve a plurality of data samples centered at said sample location, wherein a number of samples retrieved is equal to the number of samples of said model function selected in step (a); (e) regressing the data samples retrieved at said sample location selected in step (d) to said model function to produce a regression gradient value; (f) storing and displaying said regression gradient value at the corresponding sample location; and (g) repeating steps (d) through (f) for each sample location of said plurality of sample locations.
