Yes, I would think the properety will go up. If you have forgot:

Talisman Energy Inc. now estimates its North American lands have as much as 132 trillion cubic feet of unconventional natural gas in place, more than 30 tcf of which may be recoverable, its chief executive said yesterday. Talisman, which has spent the past 20 months reshaping its asset portfolio to focus on longer-term opportunities, also aims to make producing gas from shale plays in British Columbia, Alberta, Pennsylvania and Quebec profitable at a US$4 per thousand cubic feet, said John Manzoni, the company's chief executive. "We've learned more about that land base and we now estimate 132 tcf of gas in place. We believe this to be a more tightly defined estimate than last year," Mr. Manzoni said.
