First of all, some shale gas is economically.... Primarily the shale gas being produced in the U.S. basins, such as the shale gas in Horn River, for example, is going to be relatively costly, and again, all conventional gas is not equal. There are some wells that are more than economically viable today and some that are simply not. You can't really compare. All shale gas is not equal, and all conventional gas is not equal.
