The U.S. Geological Survey increased its estimate of the amount of natural gas that could be recovered through hydrofracking in the Marcellus Shale formation but the new estimate is still far lower than another federal agency’s predictions.
The Hill reports:
The U.S. Geological Survey this week greatly increased its estimate of recoverable natural gas in the Marcellus Shale formation that underlies major areas of Pennsylvania, New York and other states.
But while USGS boosted its mean estimate from 2 trillion cubic feet to 84 TCF — almost enough to meet four years of current U.S. demand — the figure is far lower than the federal Energy Information Administration’s (EIA) most recent projection.
EIA, the Energy Department’s statistical arm, estimates 400 TCF in its most recent annual forecast in April, but the new data could lead to a lower projection. On Thursday, a spokesman said EIA’s next forecast would fold the USGS numbers into EIA’s modeling.
“Incorporating the new USGS resource assessment will lower the assumptions about the technically recoverable natural gas resources in the Marcellus that will be used in the next Annual Energy Outlook,” spokesman Jonathan Cogan said in an email.
There were very large estimates of the recoverable natural gas in similar formations in Northern Michigan, but test wells have so far failed to produce as much gas as predicted.
