Is the U.S. shale boom over already? Kurt Cobb at Oilprice.com says beware optimism as he lays out the case to be skeptical of the long-term prospects for shale energy.
Cobb: "First, in the United States, home of the hydraulic fracturing 'miracle,"'domestic natural gas production has been flat since January 2012.
"The shale gas revolution may well be over in the United States as the current production level becomes increasingly difficult to maintain in the face of ferocious decline rates for shale gas wells--rates that range between 79 to 95 percent after just three years according to a comprehensive survey of 65,000 oil and gas wells in 31 U.S. shale plays.
"This means that at least 79 percent of all shale gas production must be replaced every three years just to keep shale gas production flat!
"With shale gas making up more than 34 percent of all U.S. production in 2011, merely keeping overall domestic production stable will be a formidable task and, given these decline rates, one with no historical precedent."
