Exactly how much unconventional gas lurks outside America is a matter for conjecture, but the list of countries with potentially large reserves grows steadily. Canada and Mexico are known to have lots. Australia already produces coal-bed methane and has plenty of shale and tight gas too. South Africa also has big deposits, though a fracking moratorium was announced last year. Argentina and India could join the shale club, and so could countries that already export conventional gas, such as Algeria and Libya. Even Russia and Saudi Arabia, the largest conventional oil producers, have the stuff. But the biggest shale-gas reserves may be lurking in China. At the end of last year the IEA estimated the country's total recoverable resources at 50tcm, over 70% of it in shale beds, most of the rest coal-bed methane. China already extracts prodigious quantities of the latter--some 10bcm last year. Only a handful of test wells for shale gas have been sunk, and it looks as though the geology may make it harder to get at than America's.
