The Marcellus Shale Coalition distributed a story from the Erie (Pa.) Times-News on how drilling for natural gas is likely to spread into the Erie area.
To date, no wells have been drilled in Erie or Crawford counties.
The area sits atop both the Marcellus and Utica shales.
It's just a matter of time, said Kathryn Klaber of the Marcellus Shale Coalition, a pro-drilling group, during a workshop at Penn State Behrend.
"There's no reason why the birthplace of the oil and gas industry won't play a major role," she said.
Elsewhere in northwest Pennsylvania, 74 wells have been drilled in Clarion County, 179 in Elk County and 211 in Potter County, according to state records.
