This course provides a comprehensive and practical understanding of methods of evaluation and classification of hydrocarbons resources and reserves (PRMS, SEC) and related issues, especially risks and uncertainties and how to assess/mitigate these risks and uncertainties.

The objective of the course is to provide a good understanding of evaluating and reporting oil and gas resources and reserves.

The following areas will be covered in some detail:

The different international systems for definition & classification of petroleum resources and reserves
The difference between reserves, contingent resources and prospective resources
The different technical methods for estimating reserves and resources
The evaluation methods of the risks and uncertainties related to reserves estimations
The role of petroleum economics in reserves estimation
The project-based approach adopted for reserves estimation
The importance of determining the discovery status and commerciality in resources classification.
Reserves and resources from incremental projects
Deterministic and probabilistic methods for reserves and resources estimation
Aggregation of reserves and resources

The course is designed for:
Geoscientists, reservoir engineers, asset managers, economists, government representatives interested or involved in resources and reserves estimation and reporting, as well as related risks & uncertainties assessment.
