List of countries by natural gas proven reserves

This list is based on the CIA World Factbook (when no citation is given).

Based on data from EIA, at the start of 2021, proven gas reserves were dominated by three countries: Iran, Russia, and Qatar.

Sources that consider Russia in possession of the world's largest proven reserves include the US CIA (47,600 cubic kilometers),[2] the US Energy Information Administration (EIA) (49,000 km3),[3] and OPEC (48,810 km3).

Due to constant announcements of shale gas recoverable reserves, as well as drilling in Central Asia, South America, Africa, and deepwater drilling, estimates are updated frequently.
