Chapter 8: A Subtle AVO Anomaly
In this example, AVO analysis successfully identified a gas effect in a subtle, poorly defined amplitude anomaly on a line with acquisition difficulties. AVO analysis correctly predicts the contents of several wells on the seismic line.
AVO can be successful in distinguishing pay sands from wet rocks.
Iterative surface-consistent amplitude balancing revealed an AVO anomaly not apparent after one pass of balancing.
