An important study on possible health impacts of natural gas drilling is still looking for additional funding.
Geisinger Health System spokeswoman Amanda O'Rourke said Wednesday the $1 million grant that was announced in February 2012 remains the only funding for a project that was projected to cost at least $25 million.
Geisinger plans to look at health histories of hundreds of thousands of patients who live near Marcellus Shale gas wells in Pennsylvania. Geisinger is based in Danville.
Officials say drilling in Ohio's Utica shale region nearly doubled the output of oil and natural gas there since 2011.
The Ohio Department of Natural Resources announced Thursday that the drilling process known as hydraulic fracturing, or fracking, in the shale region of eastern Ohio increased the oil output by 93 percent and the natural gas output by 80 percent in that time.
A newspaper reports that injection drilling in Ohio hasn't met the initial expectations of state officials this year.
The Columbus Dispatch reports that Ohio Department of Natural Resources officials had told state legislators in March that as many as 250 of the natural-gas and oil wells would be drilled in eastern Ohio Utica shale by the end of the year.
But state records show that only 165 wells have been completed, with 22 more being drilled.
