This article introduces a new attribute called SPICE (spectral imaging of correlative events) that calculates a bed-form boundary framework from the seismic data, and highlights detail from subtle changes in the seismic wavelet. The concept of spectral imaging is presented in the context of a well-log model and its relationship to impedance layering. Further validation of the method is provided by a detailed sequence stratigraphy analysis using well logs and seismic data from the northern Gulf of Mexico.

The technique, based on wavelet transform decomposition and singularity analysis of migrated seismic data, uses the localization properties of the wavelet transform...
