You mean SOME Alaska gas isn`t marketable. Unless what conoco has been exporting to Asia is a figment of my imagination.  No that gas wasn`t slope gas but is was Alaska gas and there is more of it than we ever thought.  as for demand, the last figure I heard was that there was 160 bcf a day spoken for, to fill an estimated market for 200 bcf a day by 2024.  So the demand window for at least 40 bcf a day is there. It`s just a question of what an investor expects as a rate of return on the investment.  If Alaska bears, with it`s vast resource value, a lower internal rate of return than Exxon investors and enjoy the tax status we would receive from investing in state infrastructure (like a common carrier gasline!) then we would reap the other "benefits" of limitless affordable natural gas across this state in short order.   I`d rather we invest in our own gasline and enjoy the benefits it would bring to state infrastructure, than not do it and spend our savings wastefully on oil credits.
