How deep is the Marcellus Shale?
9,000 feet
The Marcellus shale occurs as deep as 9,000 feet below ground surface. At greater depths, the overlying rocks cause greater pressure in the Marcellus formation which can result in higher production rates if properly stimulated.
Is there oil under the Marcellus Shale?
EIA estimates proven reserves in the Marcellus Play of 77.2 trillion cubic feet (Tcf) at year end 2015 which makes it one of the largest natural gas plays in the U.S. The Marcellus has oil reserves of 143 million barrels (MMbbls).
How deep do fracking wells go?
“The drilling comes first and then the fracking.” Wells are drilled straight down to depths ranging from 6,000 feet to more than 14,000 feet, cutting through dozens of geological layers, including pockets of drinking water.
What is the average depth of natural gas well in Pennsylvania?
**EGSP = Eastern Gas Shales … on data extracted from PAGWIS in October 2010, the average water well depth in Pennsylvania ranges between 65 and 340 ft (20-104 m; Figure 18), with bed rock encountered at depths of about 15 to 60 ft (5-18 m).
How much natural gas is in the Utica Shale?
about 38 trillion cubic feet
The United States Geological Survey’s mean estimates of undiscovered, technically recoverable unconventional resources indicate that the Utica Shale contains about 38 trillion cubic feet of natural gas, about 940 million barrels of oil, and 208 million barrels of natural gas liquids [15].
What is the depth of the Utica formation?
The Utica formation reaches subsea depths of up to -13,000 feet in a northeast trending arc through Pennsylvania and is shallowest at the junction of Ohio, Indiana, and Kentucky and along the outcrops. The area where most producing wells are found has a subsea depth ranging from -5,000 to -11,000 feet.
Where is the Utica Shale located in the United States?
U.S. Energy Information Administration | Utica Shale Play 11. The Utica formation is thickest in western Ohio and the northwest corner of Pennsylvania at 200–300 feet and thins out to 50 feet or less in southern Ohio and northern Kentucky.
How deep below the Marcellus is the Utica River?
In central Pennsylvania, the Utica can be up to 7000 feet below the Marcellus Shale, but that depth difference decreases to the west. In eastern Ohio the Utica can be less than 3000 feet below the Marcellus.
What is the difference between the Marcellus Shale and Utica Shale?
The rock units that occur between the Marcellus Shale and the Utica Shale follow this trend. In central Pennsylvania, the Utica can be up to 7000 feet below the Marcellus Shale, but that depth difference decreases to the west. In eastern Ohio the Utica can be less than 3000 feet below the Marcellus.
