The Marcellus Shale is named for a distinctive outcropping near Marcellus,
New York, and extends through much of the Appalachian Basin. Stretching
primarily across portions of Pennsylvania, New York, Ohio and West Virginia,
experts estimate that it may be one of the largest onshore natural gas fields in
North America. The formation, which ranges from 40 to more than 200 feet
thick, has an estimated 141 trillion cubic feet of natural gas reserves
according to the U.S. Department of Energy.
Approximately 4.3 million gallons of water is used to hydraulically fracture
a Chesapeake well in the Marcellus Shale.
That's less than the amount of water that flows over Niagara Falls in seven seconds.
Produced water is a byproduct of natural gas and oil extraction. Generally, this
water is filled with sand, silt and returned fracturing fluid. It travels from
the producing formation to the surface along with natural gas and oil during
completion and production operations.
Our Marcellus North District treats and recycles approximately
97% of the produced water associated with operations.

Or about enough water to complete more
than two Marcellus Shale wells a month.
