International natural gas reserves and resources. Countries divide natural gas into reserves (the amount economically extractable at current prices) and resources (the amount technically extractable if the price is high enough).

Reserves and resources are given in the table below in trillion cubic metres for selected countries as available (“n/a”

means not available):

Reserves Resources Australia 3.1 11.6 Canada 1.8 11.0 China 3.0 35.1 Poland 0.2 5.3 Qatar 25.8 n/a Russia 47.5 n/a United States 7.7 24.4 World Total 187.1 n/a
