The DHI Interpretation and Risk Analysis Consortium began in 2001 under the leadership of R&A consultants Mike Forrest, Rocky Roden, and Roger Holeywell. The Consortium has built a seismic amplitude anomaly interpretation and risk analysis application called SAAM (Seismic Amplitude Analysis Module). The SAAM software is used to risk seismic amplitude anomalies in all four AVO Classes. Information on more than 300 drilled DHI prospects is currently in the software database for analysis to help select the most significant seismic anomaly characteristics and understand reasons for failure.
The Consortium Goals are to:
- Address seismic amplitude anomalies, the data behind the anomalies, and their impact on prospect assessment.
- Design process improvements in the SAAM software to characterize seismic amplitude anomalies in a consistent, systematic, and thorough manner.
- Calibrate the assessments with documented occurrences of recoverable hydrocarbons in the subsurface and failures through prospect reviews. Prospect reviews are the highlight of the consortium meetings; members present prospect technical data, and after detailed discussion and risking by all members, the drilling result is disclosed. This is a great learning experience for all. The prospect information, including recognizing the discussion and questions by consortium members, is inputted into the SAAM prospect database.
The Consortium consists of two groups of oil and gas companies:
U.S. Group: We have five one-day meetings per year in Houston.
European Group: We will have three two-day meetings per year in Europe.
Both U.S. and European groups contribute to and share the SAAM prospect database. Company members may send representatives to either or both Houston and European meetings.
Peer Group Prospect Reviews (a unique learning experience)
- Technical presentations and discussions, consortium consensus on Pg (DHI) and then drilling results disclosed
- Representing AVO Class Prospects (offshore and onshore worldwide)
Database Analysis (difficult to duplicate in the Industry)
- Reasons for success and failure
- Detailed analysis of AVO Class 3 and 2 anomalies
- Select studies of AVO Class 1 and 4 anomalies
- Use SAAM prospect database to estimate a calibrated Final Pg, probability of geological success, on new DHI prospects.

Rose & Associates, LLP thanks the over 60 oil companies who have participated in the DHI Consortium phases over the last 18 years. Current membership is 30 companies. If your organization is interested in joining the consortium, please contact Mike Forrest or Rocky Roden.
Q: What is the cost to join the U.S./European groups in the DHI Consortium?
A: The U.S./European Consortium fee is $35,000. New members must purchase SAAM software (final product of the previous phase). Each phase of the consortium is 12 months on a calendar basis.
Q: Can I purchase SAAM software separate from joining the consortium?
A: Yes – at a cost based on oil company annual production (or equivalent). The prospect database is not included in software sales outside the Consortium. There is no maintenance fee – SAAM maintenance and upgrades are done in the Consortium.
