is this right, page-11

There are different ways you can calculate it.
The article in the link talks about gas in Australia which is a lot cheaper (I think), but some of the reports on the gdn website have more "accurate" figures - basically saying 440bcf = $10/share based on gas prices in the US, and taking out operating costs and royalties etc, and probably once it is all proven and in production etc (and not stuck on the other side of 800 feet of stuck pipe). 3tcf is pretty much 7*440...
but there is a lot to happen between now and then.

Will be a good rocket ride once it gets going...
