Great post, can't recall where I read it but I saw 240,000 plugged wells(don't want to upset anyone here)It's hard to imagine unplugging them(whether its 400 or 240,000) could not be beneficial to the countries needs.
240,000 using modern technology to produce 20 a day (or more)is 4,800,000 a day. For a year it is 1,750,000,000.
Of course the amounts will be somewhat less than that due to all 240,000 capped wells will not come back online at the same time, many of them are down a day or two a month for maintenance, etc.
Still, it is a significant number both for actual supply and for psychological value.
