Chapter 2: Processing for AVO Analysis
AVO processing should preserve or restore relative trace amplitudes within CMP gathers. Reflections must be correctly positioned in the subsurface. Data quality should be sufficient to ensure that reflection amplitudes contain information about reflection coefficients. The production of AVO interpretation aids are also a part of AVO processing.

A cursory look at the contents of the book might lead the reader to belive that AVO is not a successful hydrocarbon indicator, as we show many examples of AVO predictions gone awry, and dry holes drilled based on AVO anomalies. However, a closer look at the pages will give the reader the message we are trying to convey: used properly and cautiously, AVO can be a valuable tool for direct detection. The preponderance of unhappy endings in the book is unavoidable, as the goal of this book is to provide information that may prevent other dry holes being drilled. Inevitably, the best lessons are learned from mistakes, a statement that applies to life in general as well as to seismic interpretation.
