Yes, that's the case. To put it in perspective, the conventional natural gas in Alberta is about 100 trillion cubic feet; the coal-bed methane potential is about 600 trillion cubic feet. A vast resource on the conventional side is significantly exceeded by this resource as a potential.
The challenge is in finding ways to make this a commercial resource going forward, because it is a low-productivity resource. One of the benefits, though, is that it is a long-term-producing resource.
