Mapping of UNFC

In July 2007, the United Nations Economic Commission for Europe (UNECE) Ad Hoc Group of Experts on Harmonization of Fossil Energy and Mineral Resources Terminology charged a special Task Force to prepare a mapping of the 2004 United Nations Framework Classification for Fossil Energy and Mineral Resources (UNFC) with the classification systems of: the Society of Petroleum Engineers/World Petroleum Council/American Association of Petroleum Geologists/Society of Petroleum Evaluation Engineers (SPE-PRMS); the Committee for Mineral Reserves International Reporting Standards (the CRIRSCO Template); and, the Russian Federation.The Task Force’s mandate also included consideration of possible changes to the UNFC that would facilitate the mapping between these systems.


This publication represents the final report of the UNFC Mapping Task Force, however it should be seen as an interim step in an on-going process. In particular, the mapping work was completed in the context of proposed changes to some of the definitions of the UNFC and, as these changes have yet to be adopted, it is therefore provisional in that sense. Further, it is recognised that as more detailed mapping work is undertaken, it may be necessary to make some adjustments to the mapping between systems.


The Mapping Task Force reached several key conclusions and made some specific recommendations for due consideration by the Ad Hoc Group of Experts on Harmonization of Fossil Energy and Mineral Resources Terminology, which are outlined in this publication.
