Oil & Gas Reserves Committee

The Oil and Gas Reserve Commitee (OGRC) includes SPE members who are degreed engineers and geoscientists with at least 10 years experience in reserves and resources estimation. Additionally, other organizations may provide OGRC observers. These observers serve as liaisons between the OGRC and the respective organization on reserves and resources matters. Observers are typically highly-experienced members of similar technical societies.
