Where is Marcellus Shale found?
northern Appalachian Basin
The Marcellus Shale is a black shale, or rock formation, found throughout the northern Appalachian Basin. In Maryland, the Marcellus Shale formation is located within western Maryland from Washington, Allegany and Garrett Counties.
How far down is the Marcellus Shale?
9,000 feet
The Marcellus Shale lies underneath about 90,000 square miles of Pennsylvania, New York and West Virginia. It lies at varying depths from the surface to 9,000 feet and is believed to hold hundreds of trillions of cubic feet of natural gas, only a portion of which can be extracted with current technology.
How deep is the Marcellus Shale in PA?
Note that the Utica Shale is about 2000 feet below the Marcellus under eastern Ohio but about 6000 feet below the Marcellus in south-central Pennsylvania.
What states have Marcellus Shale?
The Marcellus play footprint extends across five states: New York, Pennsylvania, Ohio, West Virginia, and Kentucky.
What state has banned fracking?
Vermont, which has no known frackable gas reserves, banned fracking preventatively in May 2012. In March 2017, Maryland became the second state in the US with proven gas reserves to pass a law banning fracking.
What state Fracks the most?

What country does the most fracking?
The United States is the fastest-growing country in the production of shale oil, using combined techniques of deep vertical-horizontal drilling and hydraulic rock stimulation by fracking.
What is the Marcellus Shale?
The Marcellus Middle Devonian-age organic-rich formation, also known as Marcellus Shale, extends in the subsurface from New York State in the north to northeastern Kentucky and Tennessee in the south and is the most prolific natural gas-producing formation in the Appalachian basin.
How deep is the Marcellus Formation?
The top of the Marcellus formation ranges in elevation from 1,000 feet to -8,000 feet subsea depth (measured depth from 100 to 9,900 feet) and primarily produces gas in northeast Pennsylvania, but becomes more liquids-richin less thermally mature areas of southwestern Pennsylvania, West Virginia, and southeastern Ohio.
How to measure TOC content in Marcellus shales?
One of the best proxy measurements of TOC content in the Marcellus formation is its gamma-ray count. A strong correlation exists between the organic content of Appalachian shales and gamma-ray log intensity (Schmoker, 1981).
What are the two parts of the Marcellus interval?
The Marcellus interval is divided into two members: the lower Marcellus/Union Springs Shale and the upper Marcellus/Oatka Creek Shale. The Marcellus exhibits several different pressure regimes across the Appalachian basin.
