100 years of natural gas as Chesapeake CEO Aubrey McClendon himself himself AND the President proclaim?  Not so fast a rush to judgment, sez the NY Times quoting the US Energy Information Administration -- http://www.nytimes.com/2012/01/29/us/new-data-not-so-sunny-on-us-natural-gas-supply.html?_r=1  Looks like folks had better follow through on those plans to superinsulate their houses and downsize their footprints.

WASHINGTON — Just how much natural gas is trapped underground in the United States? 

The difficulty and uncertainty in predicting natural gas resources was underscored last week when the Energy Information Administration released a report containing sharply lower estimates. 

The agency estimated that there are 482 trillion cubic feet of shale gas in the United States, down from the 2011 estimate of 827 trillion cubic feet — a drop of more than 40 percent. The report also said the Marcellus region, a rock formation under parts of New York, Ohio, Pennsylvania and West Virginia, contained 141 trillion cubic feet of gas. That represents a 66 percent drop from the 410 trillion cubic feet estimate offered in the agency’s last report. 

The Energy Information Administration said the sharp downward revisions to its estimates were informed by more data. “Drilling in the Marcellus accelerated rapidly in 2010 and 2011, so that there is far more information available today than a year ago,” its report said. Jonathan Cogan, a spokesman for the agency, added that Pennsylvania had made far more data available than in previous years. 

Under the agency’s new estimates, the Marcellus shale, which was previously thought to hold enough gas to meet the entire nation’s demand for 17 years at current consumption rates, contains instead a six-year supply. The report comes just five months after the United States Geological Survey released its own estimate of 84 trillion cubic feet for the Marcellus shale.
