The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey. The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 208 million barrels of unconventional natural gas liquids.

The Utica Shale lies beneath the Marcellus Shale, and both are part of the Appalachian Basin, which is the longest-producing petroleum province in the United States. The Marcellus Shale, at 84 TCF of natural gas, is the largest unconventional gas basin USGS has assessed. This is followed closely by the Greater Green River Basin in southwestern Wyoming, which has 84 TCF of undiscovered natural gas, of which 82 TCF is continuous (tight gas). (more…)

USGS Releases U.S. Oil & Gas Reserve Growth Estimates

WASHINGTON – The U.S. Geological Survey (USGS) has released a new estimate for potential additions to domestic oil and gas reserves from reserve growth in discovered, conventional accumulations in the United States. The USGS estimates that the mean potential undiscovered, conventional reserve additions for the United States total 32 billion barrels (bb) of oil, 291 trillion cubic feet (tcf) of natural gas, and 10 bb of natural gas liquids, constituting about 10 percent of the overall U.S. oil and gas endowment.

“As part of the Obama Administration’s all-of-the-above energy strategy, we are taking aggressive steps to safely and responsibly expand domestic energy production,” said Interior Secretary Ken Salazar. “USGS’s ongoing work to identify and estimate U.S. energy supplies – and to make that information available to everyone – is fundamental to our efforts to continue to grow America’s energy economy.” (more…)
