This two-day workshop presents the fundamental components of the Petroleum Resources Management System (PRMS) of the Society of Petroleum Engineers (SPE) and provides examples of classification of recoverable volumes of oil and gas in prospective resources, contingent resources, and finally, reserves as the prospects advance maturity.

At the end of the workshop, participants will fully understand the PRMS and how to allocate recoverable volumes to the appropriate reserve categories or resources, and to the project's maturity sub-class. The theoretical material of the course is complemented with exercises to strengthen the concepts on which the PRMS is based.

The resource definitions and course reservations will focus on the specific methodologies used in the PRMS, but they will also compare the classification system and definitions with those used in SEC and other rules.


The material covered in this workshop is practical, and includes advice and ideas applicable to the classification of recoverable volumes of oil and gas accumulations and evaluates the range of uncertainty of the estimates of recoverable volumes.
