Abstract:

Key Learnings from a 25-year Worldwide DHI (Direct Hydrocarbon Indicators) Consortium

Rocky Roden*, Henry S. Pettingill, and Roger Holeywell

For the last 25 years the Rose & Associates DHI Consortium has developed a risking methodology that combines traditional geological chance factors and a DHI Index. This methodology has provided important insights from a greater than 400 well database contributed by over 85 oil companies from around the world.  Specific DHI characteristics have been categorized depending on their location, relationship to analogs, models and trends, and how they impact the seismic response in the sediment column.  Data quality including seismic acquisition and processing methods, rock and fluid property information from wells, and modeling play an important part in the risk analysis process.  The database from this consortium has provided information on the most important DHI characteristics, reasons for failure, and the identification of a DHI Threshold Effect that has significant implications on well success rates.  It is clear from the risking process that the incorporation of geology is critical. The identification of multiple amplitude anomaly characteristics is required for the best results, honoring the fundamentals and integration of all the DHI elements.

Speaker Bio:

Rocky has 50 years in the industry as a Geophysicist, Exploration/Development Manager, Director of Applied Technology, and Chief Geophysicist.  Previously with Texaco, Pogo Producing, Maxus Energy, YPF Maxus, and Repsol (retired as Chief Geophysicist 2001).  Presently owns his own consulting company, Rocky Ridge Resources, and has authored or co-authored over 100 technical publications and conference presentations on various aspects of seismic interpretation, AVO analysis, amplitude risk assessment, and geoscience machine learning.  Ex-Chairman of The Leading Edge editorial board and currently senior advisor with Geophysical Insights developing machine learning advances for geoscience interpretation. He is a principal in the Rose and Associates DHI Risk Analysis Consortium which has involved over 85 oil companies from around the world since 2001, developing a seismic amplitude risk analysis program and worldwide prospect database.  Rocky has a B.S. from Lamar University and a M.S. from Texas A&M.  He is a member of the SEG, AAPG, HGS, GSH, EAGE and SIPES.
