Critical Assessment of Shale Plays: Bridging the Gap with Engineers

Rose & Associates continues its series of contributions to the HGS with another installment on the critical assessment of shale plays.  For 2014, the one day course covers characterization techniques at the handoff interface between geoscientists and engineers.  After a brief refresher on using statistics to describe the uncertainty associated with various shale plays, we address play segmentation via compositing techniques and selection of segments with the preferred geologic attributes for future pilot drilling.  We then focus on the relationship between program sample size and the probability of achieving drilling pilot goals, uncertainty associated with various aspects of the production type curve, and finish with decision tree structuring and the aggregation techniques to model the development program.

This course is designed for geoscientists and engineers to enhance effective communication and characterization for unbiased profitable investing.

Biographical Sketch

Gary P. Citron (BS, Geology, State University of New York at Buffalo; MS & PhD in Geology, Cornell University)

After a twenty year career as a geoscientist, manager, and internal consultant for Amoco exploration business, Gary joined Pete Rose’s consulting firm, which focuses on the field of prospect and play risk analysis, in February 1999.  While at Amoco, Dr. Citron actively mentored younger geoscientists on prospect measurement.

Gary became Pete’s first Partner in Rose & Associates, LLP in 2001 and assumed the role of Managing Partner in 2003, leading R&A to multiple consecutive years of profitable growth.  Rose & Associates is a recognized leader in professional instruction and consultation related to the field of play and prospect characterization, leading to more reliable portfolio management. 

Dr. Citron has developed expertise in consensus building in prospect risk assessments and performance tracking of operational activity. In addition to his teaching and consulting obligations associated with conventional and unconventional resource opportunities, he coordinates a yearly gathering of risk team coordinators to share and compare best practices.  He also helps companies benchmark their predictive performance against companies in their peer group.  In 1999 he was selected by the AAPG to serve in their Visiting Geologist Program. In 2001, he received the best paper award from the AAPG’s Division of Professional Affairs, and again in 2007 he was honored for delivering a ‘Top Ten Oral Presentation’ at the AAPG annual convention in Long Beach. 

Gary regularly donates his time to the AAPG for for its education curricula, teaching courses on prospect, play and shale analysis. Gary has served in the AAPG House of Delegates and in the SPE as an Associate Editor for Economics and Management journal (SPEEM).  He is a Texas State certified and licensed Geologist who has authored or co-authored more than a dozen publications, and has been an invited and honored speaker for the SIPES, Geological Society of London, AAPG, SPE and SEG.
