9C, 4D Seismic Processing for the Weyburn CO2 Flood, Saskatchewan, Canada

A-12 9C 4D SEISMIC PROCESSING FOR THE WEYBURN CO2 FLOOD SASKATCHEWAN CANADA Abstract 1 We present a summary of the 9C 4D processing used for the seismic monitoring of a CO2 flood in the Weyburn Field Saskatchewan Canada. The resultant time-lapse anomalies for both the P- and S-wave volumes are coincident with the locations of the CO2 injection patterns. Furthermore the anomalies that we observe are extremely robust and are typically observed far before the final processed sections were produced. That is they are evident on the differenced brute stacks. We believe this is largely due to the similarity of
