Where is the Marcellus Shale formation?

Where is the Marcellus Shale formation?

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.

How deep is the Marcellus Shale in WV?

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.

How was Marcellus Shale formed?

The dark shale facies of the Marcellus were formed from flysch, a fine mud deposited in deep water; the deepening sea that deposited the Marcellus cut off the supply of carbonates that form limestone and the fine-grained flysch sediments buried the Onondaga limestone beds.

Where is Marcellus gas?

The Atlantic Coast Pipeline is a 600 miles (970 km) pipeline that is planned to enter service in 2019 and will draw gas from the Marcellus formation in West Virginia and run south to North Carolina.

Why is it called Marcellus Shale?

The Marcellus Shale is named after the town of Marcellus, New York near where it outcrops at the surface. Geologists knew for years of the presence of natural gas in the Marcellus formation.

Why do humans want to drill in the Marcellus Shale?

2) Why is the Marcellus Shale gas extraction suddenly important for natural gas production? The combination of advances in drilling and fracturing technology, the large volume of natural gas reserves, and its proximity to eastern cities have made the Marcellus Shale an important resource.

How long will a Marcellus gas well produce?

30 to 50 years
Marcellus Shale gas wells are expected to produce for 30 to 50 years, and perhaps much longer.

How much natural gas was in the Marcellus in 2002?

As recently as 2002, the United States Geological Survey in its Assessment of Undiscovered Oil and Gas Resources of the Appalachian Basin Province, calculated that the Marcellus Shale contained an estimated undiscovered resource of about 1.9 trillion cubic feet of gas.

What are the two most common types of reservoir rocks?

Reservoir rocks around the world is dominated by sedimentary rocks because generally it has primary porosity. Igneous and metamorphic rocks can be reservoir if there are in fracturing state (secondary porosity).

How deep is the Marcellus Shale in Pennsylvania?

This map was compiled by Geology.com using data provided by the Energy Information Administration, the United States Geological Survey, the Pennsylvania Geological Survey, and the U.S. Department of Energy. How Deep is the Marcellus Shale? Throughout most of its extent, the Marcellus is nearly a mile or more below the surface.

Where does the Marcellus Shale play take place?

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.

How many fractures are there in the Marcellus Shale?

The fractures (also known as “joints”) in the Marcellus Shale are vertical. So, a vertical borehole would be expected to intersect very few of them. However, a horizontal well, drilled perpendicular to the most common fracture orientation, should intersect a maximum number of fractures.
