Abstract
The present invention is directed generally toward a method of processing seismic data so as to provide improved quantification and visualization of subtle seismic thin bed tuning effects and other sorts of lateral rock discontinuties A reflection from a thin bed has a characteristic expression in the frequency domain that is indicative of the thickness of the bed: the reflection has a periodic sequence of notches in its amplitude spectrum, said notches being spaced a distance apart that is inversely proportional to the temporal thickness of the thin bed.
Further, this characteristic expression may be used to track thin bed reflections through a 3-D volume and estimate their thicknesses and lateral extent. The usefulness of this invention is enhanced by a novel method of frequency domain whitening that emphasizes the geologic information present within the spectrum. Although the present invention is preferentially applied to a 3-D seismic volume, it is alternatively applied to any collection of spatially related seismic traces.
