What states is the Marcellus Shale in?

What states is the Marcellus Shale in?

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 part of the United States contains the Marcellus Shale rock formation?

In the United States, the Marcellus Shale runs across the Southern Tier and Finger Lakes regions of New York, in northern and western Pennsylvania, eastern Ohio, through western Maryland, and throughout most of West Virginia extending across the state line into extreme western Virginia.

Where is shale oil found in the US?

The United States has significant oil shale resources, primarily within the Green River Formation in Wyoming, Utah and Colorado. These oil shale resources underlie a total area of 16,000 square miles and represent the largest known concentration of oil shale in the world.

Where is the Barnett and Marcellus Shale located?

The Barnett Shale is a geological formation and rich source of natural gas located in the Fort Worth Basin in Northeast Texas. The shale consists of sedimentary rock made of clay and quartz and spans 5,000 square miles, beneath about 18 North Texas counties.

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.

What is under Marcellus Shale?

According to the USGS assessment, the Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids.

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.

Which country has the most shale oil?

Russia
Russia has the biggest shale oil reserves in the world.

What is the difference between shale oil and oil shale?

Oil shale is different than shale oil in that oil shale is essentially rock that contains a compound called kerogen, which is used to make oil. Shale oil refers to hydrocarbons that are trapped in formations of shale rock.

Why is it called Barnett Shale?

Name. The formation is named after John W. Barnett, who settled in San Saba County during the late 19th century, where he named a local stream the Barnett Stream. In the early 20th century during a geological mapping expedition, scientists noted a thick black organic-rich shale in an outcrop close to the stream.

How long will the Barnett Shale last?

A recent study by the Bureau of Economic Geology at the University of Texas estimates that Barnett still contains 44 trillion cubic feet of recoverable gas resources, and while annual production may decline from its current peak of 2 trillion cubic feet per year, substantial output is expected to continue through 2030.

How long will the Marcellus Shale last?

Natural gas is a clean energy alternative with the lowest carbon emission per unit energy of any fossil fuel, no ash, and no smog-forming chemicals. Marcellus Shale gas wells are expected to produce for 30 to 50 years, and perhaps much longer.
