HERE AT TAB, WE COVERED THIS THREE WEEKS AGO.The biggest energy innovation of the decade is natural gas—more specifically what is called "unconventional" natural gas. Some call it a revolution.
Yet the natural gas revolution has unfolded with no great fanfare, no grand opening ceremony, no ribbon cutting. It just crept up. In 1990, unconventional gas—from shales, coal-bed methane and so-called "tight" formations—was about 10% of total U.S. production. Today it is around 40%, and growing fast, with shale gas by far the biggest part.
The potential of this "shale gale" only really became clear around 2007. In Washington, D.C., the discovery has come later—only in the last few months. Yet it is already changing the national energy dialogue and overall energy outlook in the U.S.—and could change the global natural gas balance.
... The supply impact has been dramatic. In the lower 48, states thought to be in decline as a natural gas source, production surged an astonishing 15% from the beginning of 2007 to mid-2008. This increase is more than most other countries produce in total.Equally dramatic is the effect on U.S. reserves. Proven reserves have risen to 245 trillion cubic feet (Tcf) in 2008 from 177 Tcf in 2000, despite having produced nearly 165 Tcf during those years. The recent increase in estimated U.S. gas reserves by the Potential Gas Committee, representing both academic and industry experts, is in itself equivalent to more than half of the total proved reserves of Qatar, the new LNG powerhouse. With more drilling experience, U.S. estimates are likely to rise dramatically in the next few years. At current levels of demand, the U.S. has about 90 years of proven and potential supply—a number that is bound to go up as more and more shale gas is found.
