Not Haligonian, but thanks for the post/link.
I had been looking into this as well.
Quicksilver made a preliminary estimate that its "all-in" finding, development and acquisition costs were $1.29 per 1,000 cubic feet of gas production for 2010.

I'm sure the 1000 cu. ft. will work out to a standard futures contract measure. Real pain in the butt the way some of this is expressed !!!
E.g. A volume of gas (1000 cu. ft.) is essentially meaningless without knowing the temperature and pressure but I'm sure those details are standard or can be found somewhere.
The link I posted earlier to Hal mentioned three drilling/production areas and I have to look back. An area sounding like Barnett mentioned in your article sounds like the one mentioned that drilling had been halted due to "high costs of production". Have to go back and look now.
The 1.29 per xxxx sounds reasonable if it works into a standard futures contract. I did a "back in" guess a few months back and was in the 1.50 to 2.00 range. Ticks me off that one cannot readily find an approximate cost of production.
