Two dimensions relevant for SEEA:
1) Classification by type of energy ressource: Coal, oil, gas, etc.
SEEA 2003:
EA.1 Natural resources
EA.11 Mineral and energy resources
EA.111 Fossil fuels
EA.112 Metallic minerals
EA.113 Non-metallic minerals
EA.12 Soil resources
EA.13 Water resources
EA.14 Biological resources
2) Classification by ”quality”/uncertainty:
SEEA 2003: Reference to proven, probable and possible reserves
(McKelvey type classification)
SNA 2008: 12.17 …sub-soil assets are defined as those proven subsoil
resources … that are economically exploitable, given current technology and
relative prices.
Classification by type of energy ressource:
New breakdown of EA.11 Mineral and energy - focusing on energy
EA.1
Natural resources
EA.11
Mineral and energy resources
EA.111
EA.112
Petroleum resources
EA.111.1
Natural gas
EA.111.2
Oil
EA.111.3
Natural bitumen, extra heavy oil, and others n.e.c.
Non-metallic minerals
EA.112.1
EA.112.2
EA.113
Solid energy resources
EA.112.1.1
Coal
EA.112.1.2
Other solid energy resources (oil shale,
others n.e.c.)
Other non-metallic minerals
Metallic minerals
EA.113.1
Uranium ores
EA.113.2
Other metallic minerals
EA.12
Soil resources
EA.13
Water resources
EA.14
Biological resources
Alignment with the MFA/product classification?
Classification by asset characteristics
New SEEA classification based on /aligned with the UNFC
classification
UNFC: United Nations Framework Classification for Fossil
Energy and Mineral Resources
• Endorsed by the UN Economic Commission for Europe,
• Recommended for worldwide application by the United Nations
Economic and Social Council (ECOSOC) (Resolution 2004/233)
Figure 1. UNFC Classification principle
Economic and commercial
viability (E)
Reflects whether or not there
are hindrances to extraction in
the social and economic
domain.

Feasibility
axis
Field project status and feasibility (F)
Ranges from early exploration and
research projects, to development,
production and abandonment
projects.
Geological axis
Geological knowledge (G)
Reflects the uncertainty in the
estimates.
Criteria for incorporating UNFC in SEEA:
Use the highest level possible,
i.e. no more details than needed
Main questions:
•What is the total ressource?
•How much is recoverable?
•What is the best estimate of future extraction?
Suggested SEEA classification
A. Best estimate of reserves
The experts’ best bid on what will be extracted in the future
(50 per cent probability of extraction ?)
B. Other reserves
Still recoverable, but lower probability of extraction
(Based on high bid – 10 per cent probability of extraction ?)
C. Other resources
Should hypothetical resources (G4) be left out ?

*The part included in A. Best estimate of reserves is those for which suggested extraction costs are lower than US$ 80 per Kg U (1 January 2005).
Next steps:
- Continue cooperation with the UNFC aiming at
complete integration
- The UNECE Group of Experts on Harmonization of
Fossil Energy and Mineral Resources Terminology
(AHGE) is currently working on further harmonizaton
of the terminology and a high level version of the
UNFC that is largely commodity independent.
