China leads world in estimated natural gas reserves

From a Financial Times article and graphic, national security blogger Tom Barnett has revised his top seven countries ranked by the size of their estimated natural gas reserves (here):

1. China 1,275 tcf
2. Argentina 774
3. Mexico 681
4. South Africa 485
5. US 482
6. Australia 396
7. Canada 388

“tcf” stands for trillion cubic feet.

Note that China leads all other countries by a substantial margin.

Note further that the combined total estimated national gas reserves of Mexico (681), US (482) and Canada (388) is 1,551 tcf. So North American estimated reserves exceed China’s.
