Previous one I had found (and used in brief) said:
Here's an old post that has similar 1-5 ranking expressed in tcf (like below), and the weird thing is, it agrees exactly with the FT numbers for China, Argentina, Mexico and South Africa but puts the US at 862.
This one, in bit FT full-pager says:
Big difference is US ranking/estimate.
Second one says EIA, as in U.S. Energy Information Agency, so I guess you gotta go with that one.
Or is this just weird mistake by FT?
No mistake. After some quick Googling it turns out the EIA said 862tcf a year ago and says 482tcf now, reducing its estimate of recoverable shale gas by 42%!
Betcha some industry experts refute that!
Will have to see where that number goes over time.
