Ohio Utica Shale

Marcellus shale estimate cut by U.S.

By Bob Downing Published: January 24, 2012

The U.S. Energy Department has cut its estimate for natural gas reserves in the Marcellus shale by 66 percent, citing improved data on drilling and production.

About 143 trillion cubic feet of natural gas can be recovered using current technologies, the agency said.

That's down from the previous estimate of 410 trillion cubic feet, the agency said on Monday.

The estimated Marcellus reserve is enough to fuel the U.S. for six years, down from 17 years in the previous report, the agency said.

It said about 462 trillion cubic feet can be produced from shale basins across the United States, down 42 percent from the 827 trillion cubic feet in last year's outlook.

Shale gas is expected to account for 40 percent of total U.S. dry gas in 2035, up from the 23 percent in 2010, Energy said.

The U.S. could become a net exporter of liquefied natural gas in 2016 and a net exporter of natural gas in 2012, the agency said.
