I attribute that rumor solely to a messed up AP title.
Her you can see the title:
Utica shale, below the Marcellus, contains large gas, oil reserves, study shows
http://www.pennlive.com/midstate/index.ssf/2012/10/utica_shale_below_the_marcellu.html
Next you find the exact same AP article with the title:
U.S. Geological Survey: Pennsylvania has natural gas and oil under Utica Shale
http://www.eveningsun.com/news/ci_21712618/u-s-geological-survey-pennsylvania-has-natural-gas
Neither article mentions anything about being beneath the Utica. Both reference the Utica being beneath the Marcellus.
Both reference the information coming from the recent USGS assessment of the Utica as the source of information. Neither the announcement, the abstract nor the report made an mention of anything beneath the Utica. It only mentioned the Utica being beneath the Marcellus.
