At the Eclipse Rescources site   www.eclipseresources.com   there is a flyer created May,2012

which shows a map on page three of these two projects:

Senecaville Project; liquid rich utica; 37,000 gross acres

Ohio River Project; liquids rich marcellus and dry utica: 11,000 gross acres to date

The Senecaville Project covers four Ohio counties and the Ohio River Project covers three counties in two states--Monroe Co, OH and Tyler and Wetzel Co ,WV

What if any is the difference between liquids rich utica and liquid rich marcellus?
