Course Description

This course explores the theory and methodology of seismic Direct Hydrocarbon Detection Interpretation (DHI) including discussion of the various techniques, their strengths, weaknesses and pitfalls. Over the past several years and on an ongoing basis, Rose & Associates has led industry consortiums to develop a DHI interpretation work process guide and educational tool to help risk seismic amplitude anomalies. The methodology (in software called SAAM) to evaluate all AVO class amplitude anomalies will be described including basic risk analysis definitions and analysis, prospect exploration settings, seismic and rock physics data adequacy, and numerous anomaly characteristics. Prospect examples and associated probabilities of geological success will be shown. Trends and “lessons learned” from the drilled prospects in the database will be reviewed in a qualitative and quantitative manner.
