marcellus shale basal

Schistes de Marcellus — Wikipédia

Les schistes de Marcellus (« marcellus shale » » en anglais) ou bassin de Marcellus est le nom d’une formation géologique de roches sédimentaires située en Amérique du Nord dans le bassin des Appalaches, principalement sous le territoire de la Pennsylvanie et à cheval avec la Virginie-Occidentale, l' État de New York et l' Ohio, à une profondeur de 4 000 à 8 500 pieds.

Marcellus Formation Wikipedia

From Wikipedia, the free encyclopedia 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, it extends throughout much of the Appalachian Basin.

forms the basal unit of a thick sequence of clastic sedimentary rocks from the Middle to Upper Devonian (390–360 million years ago) in the Appalachian Basin. The sediments were derived from highland areas in present- day New England. The black, organic-rich mud of the Marcellus Shale was emplaced as a relatively uniform layer across the basin, in anoxic and probably shallow water, prior to

API Marcellus Shale

The Marcellus Shale is rich in natural gas resources and is estimated to be the second largest natural gas find in the world. The 400 year-old rock contains approximately 410 trillion cubic feet of shale gas and could supply U.S. consumers' energy needs for hundreds of years, according to the U.S. Energy Information Administration. Technological advances such as horizontal drilling paired with

The Devonian Marcellus Shale and Millboro Shale

Another basal unit, the Huntersville Chert, underlies the Marcellus in the southern part of the basin. The Devonian section is compressed to the south, and the Marcellus Shale, along with several overlying units, grades into the age-equivalent Millboro Shale in Virginia. The Marcellus-Millboro interval is far from a uniform slab of black rock

Shumaker also proposed that south of the Salina pinch-out, the basal detachment zone occurred within the Devonian interval. It is proposed that this detachment and extensive movement in the Devonian section led to severe compromise of seals above the Marcellus Shale and subsequent loss of hydrocarbons and pressure. Figure 9 is an overlay of the Tully Limestone isopach with the regional
