In some basins it is more cost-competitive than conventional gas. It's hard to make a generalization like that, because each basin and each producer has a different cost situation, and supply basins are different.
That said, what we've seen, not only in the basins that we connect customers in in northeast B.C. but also in the other supply basins in which Spectra Energy is active in North America, is that these unconventional gas plays have become among the more leading and most cost-competitive regions to produce gas from. In some cases we're still seeing continued development of conventional gas, but in other areas we're seeing declines in conventional gas production. From that, I think you could make the assumption that in those areas, additional conventional gas production isn't as cost-competitive.
