The United Nations Framework Classification Fundamentals explained

Why UNFC? Effective management of resources requires accurate assessment of the supply base of fossil energy and minerals Recoverable resources must be described in a manner consistent with scientific, social and economic information and which need to be consistent with the information describing the projects to recover these resources A number of standards have evolved over time in response to professional needs and local requirements There has been a natural development towards a common global standard The United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources was adopted in 2009

F E G Geological knowledge Project feasibility Socio-economic viability The UNFC system consists of three axes UNFC: United Nations Framework Classification for Fossil Energy and Mineral Resources

F4F4 E1E1 E2E2 E3E3 F1F1 F3F3 F2F2 G2G2 G1G1 G3G3 G4G4 Geological knowledge Project feasibility Socio-economic viability In an early stage of exploration the geological knowledge is limited, the project feasibility and socio-economic viability are uncertain G4: limited geological knowledge F3: project feasibility uncertain E3: Socio- economic viability uncertain Status: E3-F3-G4 or 334

F4F4 E1E1 E2E2 E3E3 F1F1 F3F3 F2F2 G2G2 G1G1 G3G3 G4G4 Geological knowledge Project feasibility Socio-economic viability Geological knowledge has increased, development of project has become more feasible and economically more viable F2: development is feasible G2: Geology is better understood E2: development seems economically viable Project has moved from 334 to 222

F4F4 E1E1 E2E2 E3E3 F1F1 F3F3 F2F2 G2G2 G1G1 G3G3 G4G4 Geological knowledge Project feasibility Socio-economic viability Project has been developed, is economically viable and is producing F1: project developed and producing E1: producing Project has moved from 222 to 112 next

The full version of the UNFC system with most-used categories

These columns categorize the project This column describes the type of project This column describes the potential recovery A simplified 2D model is available to classify most common categories

Exploration projects: category 3 3 4

Potentially Commercial projects: category 2 2 2

Commercial projects: category 1 1 1

Other resources classification systems CRIRSCO and PRMS Petroleum Resources Management System (PRMS) Defined in 2007 by: Society of Petroleum Engineers (SPE) American Association of Petroleum Geologists (AAPG) World Petroleum Council (WPC) Society of Petroleum Evaluation Engineers (SPEE) Society of Exploration Geophysicists (SEG) Committee for Mineral Reserves International Reporting Standards (CRIRSCO): established in 2006, partly based on the McKelvey system and Joint Ore Reserves Committee (JORC) code.

Other resources classification systems CRIRSCO and PRMS Classification systems like CRIRSCO and PRMS are used for specific industries like mineral extraction or petroleum production. Other classifications include local system in use in countries like Norway, Russia and China, amongst others. They have evolved over time in response to professional needs and local requirements. The UNFC is a classification system applicable to different industries. By covering all extractive activities, UNFC captures the common principles and provides a tool for consistent reporting for these activities, regardless of the commodity. Mapping between the various classification systems and UNFC provide a common understanding of resources between local and global resources classification.
