Gulf of Mexico shelf framework interpretation using a bed-form attribute from spectral imaging

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.
