Chapter 6: AVO Anomalies Downdip of Production
In this chapter we describe the development of two fields in the Yegua formation. In both cases, the fields correspond to amplitude anomalies that are also AVO anomalies at the location of producing wells. In both cases, the amplitude anomalies on stacked and poststack migrated sections extend down-dip of the AVO anomaly.
Figures & Tables
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.
