The Norwegian Offshore Directorate's resource classification and definitions:
Resource classes:
- Resources is a general term for all oil and gas that can be recovered
- Resources are classified according to maturity, which measures how far along they are in the planning phase leading to production
- The primary classifications are reserves, contingent resources and undiscovered resources
- Contingent resources are resources in projects awaiting a development decision
- Reserves and contingent resources make up the total discovered recoverable resources
- Reserves are recoverable petroleum quantities not yet produced, but which have been approved for production
You can find a more detailed overview of discoveries and fields, as well as the distribution across resource classes, on the Norwegian Offshore Directorate's FactPages.
