So far as the B T U Tax is concerned, erm it's really  a political issue as to where the administration or the Congress in the end decide to place the tax, I mean in very simple terms the nearer you place it to the consumer, the more effective it is, but the less politically palatable it is  which because consumers vote and oil companies don't an and so er I think it will be political pressure to push it nearer to the well head which will be less good for the oil and gas producers.
