DHI Interpretation and Prospect Risking

This 2- or 3-day course covers all aspects of the evaluation of exploration prospects that are supported by seismic anomalies known as Direct Hydrocarbon Indicators (DHIs, also known as HCIs or DFIs). It has a strong practical orientation that uses actual prospects and realistic exercises to illustrate the applications of the various concepts and analytical procedures involved in the technical evaluation and investment decision process of DHI-supported prospects.

The course follows the characteristic workflow of evaluating DHI projects, including both theory and application, and integrates the geological and geophysical aspects of interpretation. This version of the course, tailored to companies that are members of the Rose & Associates DHI Evaluation Consortium, includes full explanations of the Consortium’s proprietary DHI risking software, Seismic Amplitude Analysis Module (SAAM).  The course also gives the participants a global context of DHI-driven exploration, as well as how to use SAAM’s 360-well calibration database for analog comparisons and global trends. Completion of the course should prepare participants for immediate application of all concepts and techniques in the risk and resource evaluation of DHI prospects.
