Chapter 7: A Processing Comparison
AVO exploration leading to the discovery of a field is described in this case history. Processing of the subtle amplitude response at the prospect using three different processing streams led to different results.
Field analogs can determine the type and strength of the AVO anomaly expected at a prospect in the same trend.
AVO anomalies that are not strongly developed can be changed and even eliminated by variations in the processing stream.
Good communication between the processor and interpreter is needed to incorporate acquisition and processing information into AVO interpretation.
Dip filters applied to CMP gathers to remove multiples can change relative amplitudes.
