14 Sep Just exactly how much gas is there in the Marcellus Shale?
The U.S. Geological Survey (USGS) now estimates that 40 times more gas is waiting to be recovered from the Marcellus Shale than it had thought.
The new number: 84 trillion cubic feet of natural gas. That replaces the previous estimate of a mere 2 trillion cubic feet.
The amount of gas believed to be in the Marcellus Shale is important because higher estimates of gas and monetary returns have made the shale play a bigger political football.
