New York Lacks Economically Recoverable Shale Gas

New York Shale Play Gets Major Downgrade

By Peter Mantius

BINGHAMTON, N.Y. — The real reason New York State has not allowed high-volume hydrofracking for natural gas in its Marcellus shale is that there is almost no gas that can be economically extracted, according to four retired professionals turned fracking analysts.

Their argument contradicts the gas industry’s narrative – widely accepted as fact by many landowners, investors, politicians and state regulators – that shale gas is a potential economic “game-changer” for poor, rural upstate New York.

For the past four years, two governors have repeatedly extended the state’s de facto moratorium on fracking while they tinkered with the rules. Since last fall, Gov. Andrew Cuomo has said he is waiting for the results of a vaguely defined health study, frustrating pro-gas groups with his apparent lack of urgency.

But the four analysts now argue that it’s geology – not health – that best explains Cuomo’s foot-dragging. In the governor’s cost-benefit analysis, they say, meager potential economic gains from drilling are not worth the environmental and political risk.

“The vast majority of the New York Marcellus shale is too thin (less than 150 feet thick) and too shallow (less than 4,500 feet) to yield economically recoverable natural gas,” said Jerry Acton, a retired systems engineer for IBM and Lockheed Martin who based his conclusions on drilling production results from neighboring Pennsylvania, where fracking is allowed.

Acton crunched four years of publicly available data supplied to regulators by Pennsylvania drillers. His analysis covered all 1,539 active natural gas wells drilled into the Marcellus shale in six counties that border New York. Acton found that median production results [Figure: Median IP chart, colored bars] for specific towns and counties [colored circles on map] correlate closely with the depth [white lines] and thickness [black lines & numbers] of the shale layer drilled. The deeper and thicker, the better.

That finding points to trouble for drilling prospects in New York, Acton said, because its Marcellus layer is relatively shallow and thin. While a cluster of Pennsylvania gas wells only 40 miles southwest of Binghamton have been highly successful, they tap a Marcellus layer that is much thicker and deeper than any in New York. As Pennsylvania drillers moved west of that sweet spot into thinner, shallower sections with geology similar to New York’s, gas production levels plummeted.
