The Utica Shale is a stratigraphical unit of Middle Ordovician age in the Appalachian Basin. It underlies much of the northeastern United States and adjacent parts of Canada.

Utica Shale What Is The Utica Shale Map and Information

It takes the name from the city of Utica, New York, as it was first described as an outcrop along the Starch Factory Creek east of the city by Ebenezer Emmons in 1842.

Lithology

The Utica Shale is composed of calcareous, organic, and rich shale.

The Utica shale is a major source of tight gas in Quebec, and is rapidly becoming so in Ohio.

Drilling and producing from the Utica Shale began in 2006 in Quebec, focusing on an area south of the St. Lawrence River between Montreal and Quebec City. Interest has grown in the region since Denver-based Forest Oil Corp. announced a significant discovery there after testing two vertical wells. Forest Oil said its Quebec assets may hold as much as four trillion cubic feet of gas reserves, and that the Utica shale has similar rock properties to the Barnett shale in Texas.

Forest Oil, which has several junior partners in the region, has drilled both vertical and horizontal wells. Calgary-based Talisman Energy has drilled five vertical Utica wells, and began drilling two horizontal Utica wells in late 2009 with its partner Questerre Energy, which holds under lease more than 1 million gross acres of land in the region. Other companies in the play are Quebec-based Gastem and Calgary-based Canbriam Energy.

The Utica Shale in Quebec potentially holds 4×10^12 cu ft (110×10^9 m3) at production rates of 1×10^6 cu ft (28,000 m3) per day From 2006 through 2009 24 wells, both vertical and horizontal, were drilled to test the Utica. Positive gas flow test results were reported, although none of the wells were producing at the end of 2009. Gastem, one of the Utica shale producers, took its Utica Shale expertise to drill across the border in New York state.

The Province of Quebec imposed a moratorium on hydraulic fracturing in March 2012.

Ohio

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. Map of Ohio Utica Shale drilling permits and activity by date. In 2011 drilling and permits for drilling in the Utica Shale in Ohio have reached record highs Although the prospective Utica area extends into Pennsylvania and West Virginia, as of 2013, most activity has been in Ohio, because the Ohio portion is believed to be richer in oil, condensate, and natural gas liquids.

New York

In 2009, the Canadian company Gastem, which had been drilling gas wells into the Utica Shale in Quebec, drilled the first of its three state-permitted Utica Shale wells in New York. The first well drilled was in Otsego County.

New York imposed a moratorium on large-volume hydraulic fracturing in 2008. The governor, who has the power to lift the moratorium, has said that he will make a decision before the 2014 election.

Resource size

The US Energy Information Administration estimated in 2012 that the Utica Shale in the US held 15.7 trillion cubic feet of unproved, technically recoverable gas. The average well was estimated to produce 1.13 billion cubic feet of gas. The same year, the US Geological survey estimated that the Utica Shale had 38.2 trillion cubic feet of undiscovered technically recoverable gas, 940 million barrels of oil, and 208 million barrels of natural gas liquids.

Distribution

The Utica Shale lies under most of New York, Pennsylvania, Ohio, and West Virginia and extends under adjacent parts of Ontario and Quebec in Canada and Kentucky, Maryland, Tennessee, and Virginia in the United States.

It occurs in outcrops in the state of New York and in the subsurface in the provinces of Quebec and Ontario. Parts of the island of Montreal consist of Utica shale, which affected construction of parts of the Montreal metro. In some regions of Pennsylvania, the Utica Shale reaches to almost two miles below water level. However, the depth of the Utica Shale rock decreases to the west into Ohio and to the northwest towards Canada.

It reaches a thickness of up to 1,000 feet (300 m) and can be as thin as 70 feet (20 m) towards the margins of the basin. 250 feet (80 m) are exposed in the type section.

Relationship to other units

The Utica Shale underlies the Lorraine Group and overlies the Trenton Group limestone and the Canajoharie shale in Mohawk River Valley.

The Utica Shale is divided into the Nowadaga Zone, Loyal Creek Zone and Holland Patent Zone.

It lies a few thousand feet under the Marcellus Shale.
