Where is the Marcellus Shale found in PA?
Where is the Marcellus Shale found in PA?
Found as deep as 9,000 feet below the ground surface in northeastern and central Pennsylvania, the Marcellus Formation generally becomes shallower at depths of 2,000 feet toward northwest Pennsylvania. The Marcellus Shale covers 6 states and underlies nearly 75 percent of Pennsylvania.
What area of Pennsylvania contains the most Marcellus Shale?
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-rich in less thermally mature areas of southwestern Pennsylvania, West Virginia, and southeastern Ohio …
How many Marcellus Shale wells are in PA?
Currently, there are 10,586 well locations with an active status, 9,218 of which have been drilled. There 19,617 unconventional well locations in Pennsylvania when considering all status types, 10,652 of which have been drilled.

Is Marcellus Shale a good reservoir rock?
Long known to be a source rock for many conventional oil and gas reservoirs in the Appalachian basin, the Marcellus shale is now being explored as an unconventional reservoir. In the past, however, the low permeability conditions of the shale reservoir made removal of hydrocarbons economically unfeasible.

Why is fracking bad in Pennsylvania?
Already, fracking has contaminated drinking water supplies with benzene, toluene, formaldehyde and other dangerous contaminants; dumped under-treated wastewater in rivers and streams from the Monongahela to Neshaminy Creek; clear-cut our state forestland to make way for gas wells; and are crisscrossing the state with …
How many active fracking wells in Pennsylvania?
As of May 1, 2017, Pennsylvania had 129,587 active oil and gas wells of which 10,097 active wells—7.7 percent—were unconventional wells. An unconventional formation is a geologic formation where energy generally cannot be extracted except by horizontal or vertical wells stimulated by fracking. with hydraulic fracturing …
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.
Where is most of the fracking done in Pennsylvania?
While gas production has expansive hotspots in the northeastern and southwestern portions of the state, the liquid production comes from a much more limited geography. Eighty percent of all condensate production came from Washington County, while 87% of all fracked oil came from wells in Mercer County.
