Important Note on Sources of Foreign Reserve Estimates

Reserve estimates for oil, natural gas, and coal are very difficult to develop.   The Energy Information Administration (EIA) develops estimates of reserves of oil, natural gas, and coal for the United States but does not attempt to develop estimates for foreign countries. As a convenience to the public, EIA makes available foreign fuel reserve estimates from other sources, but it does not certify these data. Please carefully note the sources of the data when using and citing estimates of foreign fuel reserves.
