Description of a Glauconitic channel by AVO analysis
Yong Xu, John C. Bancroft
AVO analysis is performed on vertical component seismic data from a line in Blackfoot. P wave reflectivity (RP) and S wave reflectivity (RS) are extracted from the CDP gathers of vertical component data after true amplitude processing. A fluid factor section is obtained from RP and RS sections using the mud-rock line derived from local dipole sonic logs. By combining RP and RS sections and well logs, the Glauconitic channel can be better interpreted. On the fluid factor section, the Glauconitic channel exhibits a stronger and more detailed anomaly.
