Wonder what Putin thinks about this new found wealth?
I personally don’t agree with that number, depending on the number of well and how many stages you have in your fracks we open up allot of area. Gas like oil is not trapped in it’s zone but it does take time for it to migrate. Maybe at some point and time it doesn’t migrate fast enough to be cost effective but it will continue to migrate non the less. I shut in a well on the backside of the ranch back in 98, it was down to about 2 barrels a day. I went in and pulled the pum. checked the tubing and put it back on line, it made 348 barrels in the first 3 weeks, today it’s making about 5 barrels a day and I expect it to be down to two here shortly. That oil and gas can only move so fast unless you have some type of secondary recovery in place such as a water flood to increase that migration.
That number sounds believable, but I haven't found decent data to back it up. But for comparison, look at the well known Bakken.

...current 24-billion boe recovery estimate...
...oil in-place estimate of 577 billion boe.
Last year the company raised that in-place estimate to 903 billion boe without increasing the recovery estimate, leaving others to speculate based on whatever recovery rate they chose to apply.
