Marcellus Shale and Natural Gas Production in New York
Marcellus Shale is a Devonian-age rock formation deposited over 350 million years ago in a shallow inland sea located where the present day Appalachian Mountains now stand.
Hydraulic fracturing, commonly referred to as “hydrofracking” or “fracking.”
A hydrofrack is where water under high pressure forms fractures in the rock, which provide pathways for gas to move to the well.

Pros & Cons (60 Minutes)
The estimate of recoverable gas from the Marcellus Shale is estimated to over 363 Tcf.
Concerns about Developing Natural Gas Wells in Marcellus Shale
Three important environmental concerns related to Marcellus Shale gas production are:
Supplying the large amounts of water needed without impacting local water resources
Avoiding degradation of small watersheds from increased erosion and sediment as large quantities of equipment and supplies are moved about on unpaved rural roads
Determining the proper methods for the safe disposal of the large volumes of spent and recovered fluids from the wells
