PRMS Reserves & Resource Assessment
The course investigates the classification and categorisation of resources within the SPE-PRMS systems. By the use of particular case studies, the course studies the boundaries between class and category when assessing resources for management and financial disclosure. The methodology for assessing hydrocarbons-in-place and resources is explained and the significance of uncertainty is described. Both deterministic and probabilistic approaches to volumetric assessment are outlined. The engineering toolkit, using static, decline curve, material balance and reservoir simulation, is described. Practical exercises and illustrations of the pitfalls and issues in resource categorisation are illustrated by examples.

Course Overview
Learning Outcomes
Participants will learn to:
- Evaluate the different categories of reserves and resources.
- Propose the reasons for uncertainty and the need to address it.
- Assess the volumetric derivation of resources, both deterministically and probabilistically.
- Appraise the limitations of resource assessment methods.
- Assure resource assessments by integrating the relationship between volumes, development plans and economics.
