WEBThe Marcellus Shale, also referred to as the Marcellus Formation, is a Middle Devonian-age, black, low-density, carbonaceous (organic-rich) shale that occurs in the subsurface beneath much of Ohio, West Virginia, Pennsylvania and New York.
Marcellus Formation - Wikipedia
WEBThe 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]
WEBThe 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.
WEBMarcellus Shale Geology & Potential. Some Basics on Reservoirs. Reservoirs are deeply buried rocks containing oil or gas (or both) that can be economically extracted. Historically, sandstones and carbonates have been the best performing reservoirs because they are more porous and permeable.
Marcellus natural gas trend - Wikipedia
WEBThe 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]
Updated geologic maps provide greater detail for Marcellus formation
WEBApr 1, 2015 · Recent updates to EIA's maps and geologic information for the Marcellus shale play help to characterize the formation's structure, thickness, and extent. EIA uses well data to construct maps showing the formation extent and structure of the productive and prospectively productive regions of the Marcellus.
