DHI Interpretation and Prospect Risking

In this two-day course, you will examine the theory and methodology of seismic Direct Hydrocarbon Detection Interpretation (DHI), which includes discussion of differing techniques, their strengths, weaknesses, and pitfalls. For the last 10 years, Rose & Associates, LLP has led an industry consortium to create a DHI interpretation work process guide and educational tool in order to help assess the seismic amplitude anomalies that lead to probability assignments and resource potential uncertainty. How to evaluate all AVO class amplitude anomalies will be described and prospect examples and associated probabilities of geological success are analyzed in closer detail. Using drilled prospects in the database, trends and “lessons learned” will be examined in a qualitative and quantitative manner.
