[crusty old prospector]

This website has a decent summary of the Utica Shale. I would say that the oil play would extend to the -8000’ contour at the most. Deeper than that, it is more than likely a gas play. Looks like the oily play will be in eastern Ohio and southern New York. At depths below -12,000’ in Pennsylvania, it is probably over mature.

That would be similar to what has been found in the Eagle Ford Shale.
