Tap To Call

DHI Consortium

The DHI Interpretation and Risk Analysis Consortium began in 2001 under the leadership of R&A consultants Mike Forrest and Rocky Roden, with software support by Roger Holeywell. The Consortium has built a seismic amplitude anomaly interpretation and risk analysis application referred to as SAAM (Seismic Amplitude Analysis Module). The SAAM software is used to risk seismic amplitude anomalies from all four AVO Classes. Information about 280 drilled prospects is currently in the software database for analysis and to help calibrate the weighting factors of the data quality and anomaly characteristics.

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 (Seismic Amplitude Analysis Module) 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 will have five one-day meetings in Houston during 2016.

European Group:  We will have three two-day meetings in Europe during 2016.

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.

Consortium 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
  • Calibrate “score values” and weighting factors using SAAM database

Rose & Associates, LLP thanks the over 60 oil companies who have participated in the DHI Consortium phases over the last 16 years. Current membership is 25 companies. If your organization is interested in joining the consortium, please contact Mike Forrest or Rocky Roden.

FAQ List

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 – the current phase ends December 2016.

The software licensing fee is based on the annual production (or equivalent) of an oil company: ranging from $5,000 to $30,000.

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.
