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]
Outcrops of the Marcellus Formation - Pennsylvania State University
WEBIn viewing this outcrop is it easy to understand why many vertical wells penetrated the entire 30m + thickness of Marcellus without encountering a single joint. Yet, even with joints spaced in excess of 5 meters, a 500 meter horizontal well could expect to penetrate upwards of 100 joints.
WEBThe U.S. Energy Information Administration (EIA) is adding and updating geologic information and maps of the major tight oil and shale gas plays for the continental United States. This document outlines updated information and maps for the Marcellus play of the Appalachian basin.
WEBThe “new” Marcellus shale play began in 2003, when Range Resources drilled a well through the Marcellus down to the Lower Silurian in Washington County, Pennsylvania. Targeted reservoirs were not productive, but the Marcellus showed promise and was successfully completed in 2004.
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]
Appalachian Basin Marcellus gas play - AAPG Wiki
WEBJan 16, 2024 · The potential limits of the Marcellus Shale play can be defined to the north, south, and east by the outcrop belt of the unit and to the west by thinning of the Marcellus Shale or its removal by a Middle Devonian unconformity surface.

Forecast of economic gas production in the Marcellus Shale
WEBJan 1, 2024 · The Marcellus Shale is predicted to produce 85 trillion SCF (TSCF) of gas from 12,406 existing wells. By drilling ∼3700 and ∼7800 new wells in the core and noncore areas, the estimated ultimate recovery is poised to increase to ∼180 TSCF.
Marcellus Shale Outcrop in Highland County, Virginia
WEBA Marcellus Shale outcrop in Highland County, Virginia, shows at the surface the object of shale gas development drilling in nearby states. Assessing undiscovered gas resources, like the USGS 2011 assessment of the Marcellus Shale, uses geologic mapping of outcrops like this in addition to extensive drilling, production, and geophysical data.
Geology of the Devonian Marcellus Shale--Valley and Ridge …
WEBThe organically rich Middle Devonian Marcellus Shale is present throughout most of the synclinorium, being absent only where it has been eroded from the crests of anticlines. Geochemical analyses of outcrop and well samples indicate that hydrocarbons have been generated and expelled from the kerogen originally in place in the shale.
