The Utica Shale is a black, calcareous, organic-rich shale of Middle Ordovician age that underlies significant portions of Ohio, Pennsylvania, West Virginia, New York, Quebec and other parts of eastern North America (see Figure 1).
The Utica Shale covers much of the northern Appalachian basin, Cincinnati-Findlay Arches, and Michigan basin and has been productive in Quebec, Michigan, New York, Pennsylvania, and Ohio. Ohio is the primary focus of current activity because this state has the thickest accumulation of the Point Pleasant formation which underlies the Utica Shale.
2 maj 2016 · The Utica map is one of several maps of low-permeability hydrocarbon formations that EIA updated with additional geologic detail. EIA has previously published updated maps of major geological and tectonic features for the Marcellus and Eagle Ford plays.
Map showing the location of the oil and gas assessment units (AU) for the Utica Shale in the Appalachian Basin Province. Utica Shale drilling and production began in Ohio in 2011. Ohio as of 2013 is becoming a major natural gas and oil producer from the Utica Shale in the eastern part of the state. [10]
Generalized map showing depth to the top of the Utica Shale. To the north in New York state, the Utica Shale equivalent is exposed at the surface. To the west, beyond the study area in Ohio, the Utica Shale is at a relatively shallow depth and has not generated hydrocarbons.
2 dni temu · Figure 3 shows areas in Ohio with potential for Marcellus and Utica development. Wickstrom points out that the Utica ranges from 3,000 to 10,000 feet in depth in the area that is prospective. In Pennsylvania, there are areas in which the Utica is as deep as 14,000 feet.
3 paź 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.
