Marcellus Formation - Wikipedia
The Marcellus Formation or the Marcellus Shale is a Middle Devonian age unit of sedimentary rock found in eastern North America. Named for a distinctive outcrop near the village of Marcellus, New York, in the United States, [3] it extends throughout much of the Appalachian Basin. [4] [5] [6]
Marcellus Shale: Results Continue to Amaze Geologists
Twenty years ago, every geologist involved in Appalachian Basin oil and gas knew about the Devonian black shale called the Marcellus. Its black color made it easy to spot in the field, and its slightly radioactive signature made it a very easy pick on a geophysical well log.
Marcellus natural gas trend - Wikipedia
The Marcellus natural gas trend is a large geographic area of prolific shale gas extraction from the Marcellus Shale or Marcellus Formation, of Devonian age, in the eastern United States. [2] The shale play encompasses 104,000 square miles and stretches across Pennsylvania and West Virginia, and into eastern Ohio and western New York. [3]
USGS Estimates 214 trillion Cubic Feet of Natural Gas in ...
Oct 3, 2019 · The Marcellus Shale and Point Pleasant-Utica Shale formations of the Appalachian Basin contain an estimated mean of 214 trillion cubic feet of undiscovered, technically recoverable continuous resources of natural gas, according to new USGS assessments.
Appalachian Basin Marcellus gas play - AAPG Wiki
Jan 16, 2024 · After a long history as a major source rock for several major Appalachian Basin oil and gas plays, the Marcellus Shale is now emerging as a major thermogenic shale-gas play with a large areal extent. After initial vertical discoveries in 2004 through 2006 and horizontal successes initiated in 2007, the Marcellus Shale play is rapidly expanding ...
Shale natural gas production in the Appalachian Basin sets ...
Sep 1, 2021 · The Appalachian Basin contains two shale formations, Marcellus and Utica, which accounted for 34% of all U.S. dry natural gas production in the first half of 2021.

Depth to Marcellus Shale Base 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.
