In this chapter, seismic-attribute spectral decomposition (SD) is used for understanding heavy-oil and bitumen sand reservoir behavior and comprehending their heterogeneities for future reservoir simulation. Spectral decomposition is performed on the migrated stack and on amplitude-versus-offset (AVO) attributes (P- and S-wave impedance reflectivity). Examples provided in this chapter are from reservoirs with cold and thermal production. The observed differences between SD performed on P- and S-wave impedance reflectivity are explained with the solid state of the oil sands at their preproduction reservoir condition. The interpretation of the seismic attributes is based on the poroelastic and viscoelastic behaviors of the...

Heavy-oil and Oil-sand Petroleum Systems in Alberta and Beyond
Oil sands, including the Athabasca Oil Sands in northern Alberta, are the second largest hydrocarbon resource on earth. In the last decade, engineering technology has evolved that can now economically produce the bitumen resource in the oil sands. This volume showcases the geology of oil sands from around the world. It highlights the Athabasca Oil sands of northern Alberta and the geochemistry of the associated bitumen resource, but points directionally toward the development of other oil-sand deposits in the world. A novel feature is the ‘case study’ approach. Although much of the perspective is sedimentological and/or stratigraphic, the substance of the book should fine wide appeal to Earth scientists working in all geoscience domains.
