DHI Consortium De-Risking DHI-driven prospects

The DHI Interpretation and Risk Analysis Consortium, established in 2001, was formed to meet the industry’s need for a consistent approach to “de-risking” DHI-driven prospects. This Consortium brings together experienced industry practitioners and well-known technical experts to enhance DHI prospect evaluation and technology, ultimately improving DHI prospect risking and valuation. The successful predictive results of the Consortium’s prospect database and member-company’s performance have been documented in several publications.

Consortium Goals

  • Address seismic amplitude anomalies and their impact on prospect assessment and decision making
  • Enhance SAAM software to analyze anomalies consistently, rigorously, and objectively
  • Calibrate assessments with drilling results
  • Networking and learning from a global group of experienced seismically-driven explorers


The Consortium has U.S. and European chapters, which both contribute to a shared SAAM prospect calibration database. This database now has over 400 prospects. Meetings include prospect reviews, technical presentations, and discussions. In 2020, virtual webinars were introduced, continuing alongside live meetings.


In-Person Meetings and Webinars

In-Person Meetings: Peer Group Prospect Reviews (a unique learning experience)

  • Prospect technical presentations and discussions, followed by entry into the SAAM software, consensus on Final Pg (DHI), and finally presentation and discussion of the drilling results
  • Consortium members contribute presentations on drilled prospects. During these presentations, the audience does not know the drilling outcome and has to debate the merits. These discussions are amazing learning experiences and provide hands-on SAAM training.
  • Representing prospects from around the world in all AVO classes
  • Discussions and presentations on important technologies to properly risk prospects


Monthly Webinars

  • Allows member company participation and learning for their geo staff across the globe, with no need for travel funding
  • Reviews of various technical presentations to maximize company participation

Analysis of Our Exclusive Database

  • Reasons for success and failure, both geologically and geophysically
  • Detailed analysis of prospects from all AVO classes
  • Use SAAM prospect database to estimate a calibrated Final Pg based on a calculated probability of geological success, and DHI Index determined from observations of the seismic data on new DHI prospects

Frequently Asked Questions

What is the cost to join the U.S./European groups in the DHI Consortium?

Please contact us to discuss pricing of membership in the DHI Consortium. New members must purchase SAAM software.

Can I purchase SAAM software separate from joining the consortium?

Yes. The prospect database is included only for members of the Consortium. Learn more about SAAM here.
