Who regulates Marcellus Shale drilling in PA?
DEP’s Bureau of Oil and Gas Management regulates the safe exploration, development and recovery of Marcellus Shale natural gas reservoirs in a manner that will protect the commonwealth’s natural resources and the environment.
Where is the Marcellus Shale located?
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.
What is the average life of a fracking well?
Fracking is a temporary process that occurs after a well has been drilled and usually takes only about 3-5 days per well. Sometimes, wells are re-fracked to extend their production, but the energy each well can produce may last for 20 to 40 years.
What is Marcellus Shale and why the sudden interest in Pennsylvania?
What is Marcellus Shale and why the sudden interest in it? The geology of the Marcellus formation suggests that areas in the northcentral and northeastern regions of Pennsylvania that have not traditionally seen much gas well drilling might be especially productive.
How are residents responding to the Marcellus Shale?
More residents overall support drilling than oppose it by a margin of 45 percent to 25 percent, with the rest in neither camp. In Washington County, the rates of support are higher, with more people having a strong opinion on the issue.
How deep is the Marcellus Shale in PA?
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.
What is the geographic extent of the Marcellus Shale in Pennsylvania and surrounding states?
The shale play is one of the largest in terms of geographic area, and the United States Geological Survey (USGS) estimates the formation’s total area to be around 95,000 square miles, ranging in depth from 4,000 to 8,000 feet.
What is the issue with the Marcellus Shale?
Water-resource issues associated with development of the Marcellus play include the 1) impact of surface-water and groundwater withdrawals for hydraulic fracturing during low-flow periods, 2) disposal of black-shale drill cuttings that may produce acidic, metals-rich drainage with elevated radioisotopes, and 3) …
When did Marcellus Shale drilling start in PA?
As for the first Marcellus Shale natural gas well, that was drilled in 2004 by MSC member company Range Resources in Washington County, Pa.
