tho primarily about the Marcellus it re-iterates 90 yr reserve estimates (at CURRENT demand rate), guesses 50 yrs if all coal plants replaced.

Doesn't look too good for T. Boone
Are there numbers or have we discussed reserve estimates for the Haynesville Shale. I seem to remember CHK saying (maybe PHK) that they would pull off 85% of well production in the first year.
