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

Interest has grown in the region since Denver-based Forest Oil Corp. announced a significant discovery there after testing two vertical 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[citation needed].

Ohio as of 2013 is becoming a major natural gas and oil producer from the Utica Shale in the eastern part of the state.

[18] 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.

[21] 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.

Some stations had to be built cut-and-cover or with a narrow split platform profile to reduce the load on the bedrock.

However, the depth of the Utica Shale rock decreases to the west into Ohio and to the northwest towards Canada.
