Resource categories:

  • 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.
  • Reserves are recoverable petroleum volumes not yet produced, but which have been approved for production.
  • The primary classifications are reserves, contingent resources and undiscovered resources.
