Recently the price of natural gas has fallen from around $13 per thousand cubic feet to less than $9 per thousand. The CEO of XTO blames the CEO of Chesapeake because the latter projected that the Haynesville shale contained incredible 245 trillion cubic feet of recoverable natural gas.

Apparently the CEO of XTO is a Republican because Democrats do not think that the prospect of future supplies of oil or gas will affect the current price.

(Personally I think that the recent natural gas price decline is more related to long-range weather forecasts of a warm winter in the US this year. This still assumes that there is a relationship between price and future supply and demand.)
