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).
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.
1 wrz 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. On its own, the Appalachian Basin would have been the third-largest natural gas producer in the world the first half of 2021 , behind Russia and the rest of the United States.
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 dni temu · Growing numbers of oil and gas companies are gearing to test the liquids-rich Utica Shale below the Marcellus formation in Ohio and Pennsylvania. Thanks to the Marcellus play, rigs capable of drilling long-lateral horizontal wells, frac crews, production infrastructure and other services and equipment are already largely in place to support ...
2 maj 2016 · The Utica formation reaches subsea depths of up to 12,500 feet in a northeast arc though Pennsylvania and is also shallowest at the junction of Ohio, Indiana, and Kentucky. The most productive wells in the Utica formation are found at subsea depths ranging from 5,000 to 11,000 feet.
The “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.
