For reference:
The Alaska North Slope Natural Gas Pipeline needs a natual gas price of at least $2.70 to be profitable.
Wonder where you got that number? Exclusive of the pipeline and only to the border? Even then it still is much lower than anything I have heard. There is an article about LNG that uses a breakeven price of $4.50 floating around however that number is clearly low. As to Alaska, the pipeline cost alone has to be in that neighborhood.
