Oil & Gas Reserves Committee

About the Committee

The Oil and Gas Reserves Committee (OGRC) is responsible for programs dealing with oil and gas reserves and resources matters, including reserves and resources definitions, terms, recommended practices, and standards. The committee disseminates reserves and resources information to other organizations, agencies, and companies involved in reserves matters, including cooperation with other committees and organizations in development and delivery of relevant training courses.

The committee currently has a chair, vice-chair, and 16 members who are degreed engineers and geoscientists with 10+ years of experience in reserves and resources estimation. There are also eight observers to the OGRC who represent their respective societies on reserves matters. Currently, observers represent the Society of Petroleum Evaluation Engineers (SPEE), the American Association of Petroleum Geologists (AAPG), the Society for Exploration Geophysicists (SEG), the Society of Petrophysicists and Well Log Analysts (SPWLA), the World Petroleum Council (WPC), the European Association of Geoscientists and Engineers (EAGE),The International Accounting Standards Board (IASB), and the Expert Group on Resource Management (EGRM) of the United Nations Economic Council of Europe.
