What Is The Marcellus Shale Formation?
The Marcellus shale formation is located in the northeast part of the United States. It is one of the most significant discoveries of natural found so far. Clean burning natural gas will undoubtedly be a big part of our energy future as we seek to reduce our dependence on foreign oil.
To learn more about the Marcellus Shale you can
visit your local library and check out some good books on petroleum geology and
sedimentary rocks. If you live in the states of Pennsylvania, New York, Ohio,
Kentucky and Virginia you may have already heard of the Marcellus Shale. It is a
layer of sedimentary, gas bearing rock known as shale that is buried as much as
a mile below the surface. It may contain, according to some geologists, up to
five hundred trillion cubic feet of natural gas.
Shale is a hard sedimentary rock that is
rich in organic material. It was formed millions of years ago in the middle
Devonian age as fine muck deposited on the floor of an ancient sea. As the shale
was covered up with other sediments and buried, eventually heat and biological
action caused natural gas to be formed from the organic material in the
Marcellus shale. Shale gas refers to the natural gas trapped in reservoirs such
as the Marcellus Shale and Barnett Shale.
Now oil and gas companies are seeing the
Marcellus shale in a new light since horizontal drilling was perfected. This
technology allows them to drill sideways across many fractures in the Marcellus
shale and therefore extract much more natural gas from a single well.
Similar shale gas formations, such as the Barnett shale in Texas, have brought thousands of jobs and income for local governments from taxes on gas royalties. Shale drilling has helped the US become energy independent and reduce our foreign trade deficit. (Update: Because of the surplus of natural gas in the U.S., exports of LNG or liquefied natural gas will begin from ports in Louisiana, Texas and other states. Some of this gas will go to Europe, helping to reduce dependence on Russian natural gas.)
