ABSTRACT
The ability to crossplot attributes from a 3-D seismic volume permits a geophysicist to identify and high grade subsets of the 3-D volume that warrant detailed inspection. In the case of amplitude-variation-with-offset (AVO) crossplotting, the seismic attributes are derived from CDP data. Crossplotting has become a fundamental
process in AVO analysis, just as it is in petrophysical analysis. Comprehending the intricacies and selection of attributes is essential for successful AVO analysis and improved seismic interpretation. AVO crossplotting of modeled seismic data derived
from well logs with the Biot-Gassmann equations provides a basis for understanding fluid substitution effects on AVO attribute interactions when crossplotting. With these model-based understandings, improved multi-attribute interpretation processes can commence with AVO crossplotting of seismic volumes.
