You might want to check your math. Existing US reserves of natural gas provide something closer to an 86 year supply.
The correct source, which contains bot reserves and consumption, country by country, is the World Statistical Report of Energy. The Bible of the industry for 70 yrs.
The EIA has always played wet gas games, which are not games and not offensive if they are consistent.
The correct units are trillion cubic meters, not feet.
US dry gas reserves consistent with how the world measures are 12.1 Tcm. Russia is 37. Iran about 34. Qatar . . . I’m on a tablet and the spreadsheet from the Bible is downstairs I don’t remember Qatar’s number. Turkmenistan is big. And I think another country or two above the US 12.1.
There is another tricky item. Consumption will also include export. So you can’t buy years unless you cut off customers.
The US is more or less dependent on shale now and gas wells notoriously die quickly.
In contrast, Russia has the Bazhenov shale, far larger than the actual sum of US shale fields . . . and Russia hasn’t even started fracking it yet. There has been no need.
