In a recent Wall Stree Journal article, “America’s Natural Gas Revolution,” Daniel Yergin and Robert Ineson opine that gas produced from shale “is already changing the national energy dialogue and overall energy outlook in the U.S.–and could change the global natural gas balance.” Mr. Yergin is the author of “The Prize: the Epic Quest for Oil, Money, & Power” which won him a Pulitzer Prize. He is now chairman of IHS CERA. Mr. Ineson is senior director of global gas for IHS CERA.
Yergin and Ineson cite the following evidence for their thesis:
— Production of gas in the lower 48 states increased 15% from the beginning of 2007 to mid-2008 – an increase fueld mostly by shale gas discoveries, and an increase that is more than most other countries’ total gas production.
— Proven gas reserves have risen from 177 trillion cubic feet in 2000 to 245 trillion cubic feet in 2008, even though the U.S. produced nearly 165 Tcf during that time.
— “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.”
Most of this new gas comes from shale plays, beginning with the Barnett Shale in North Texas, and including the Haynesville (Louisiana and Texas), Fayetteville (Arkansas), Marcellus (Pennsylvania and New York), and most recently the Eagle Ford in South Texas. Shale gas is made possible by use of horizontal drilling technology and newly developed hydraulic fracturing completion techniques.
