I hope a geologist will chime in to educate us a little about the nature of the Clinton.  I have always had the impression that in most of Eastern Ohio, the Clinton is more of a blanket formation, rather like the shales, except of course it is a sandstone. 

There will be variations in thickness and porosity from well site to well site, but in some of the sweet spots, there could be hundreds of acres of fairly uniform characteristics in which many wells are (were) quite prolific, and such areas may represent a good target for HZ drilling.

The old East Canton field represents one such spot where many dozens of wells over a large area had initial production on the order of a hundred bpd, and some wells IP of several hundred bpd.

If a Horizontal Clinton well is possible I know where I want to be..... Stark, Tuscararwas, Coshocton and Knox. Easily the best Clinton areas in the state. Forgive me if I missed 1 or 2 others. Let's don't forget the Bremen Oil Field.

James, I agree.  I'd start in the East Canton Oil Field and work my way out, likely to the southwestern trend.

And r2d2, yes, EOG got the Queenston on up.

R2, The map I checked shows the well kind of near the fringe of the field, but most would consider it to be in the East Canton field.  As far as judging the environment of deposition from the production reports, that is a bit dicey.  I would rather make that determination from a series of well logs.  The Ohio Geological Survey has a recent report on the field, OFR 2011-2, that can be downloaded for free from their website. http://geosurvey.ohiodnr.gov/publications-maps-data/open-file-reports It takes a minute or two with a high speed connection.  Highly technical, but if you are interested, friend me and I can answer some questions for you.

The Enervest horizontals are permitted Ohio Shale - queenston which obviously includes the Clinton. Is there a formation other than the Clinton that they are looking at? Shale?

One thing to bear in mind about the Boan/Marcum well is that when it was drilled in 2006 the knowledge of how to complete the well was limited. The completion/frack was done with a similar method as the barnett. It was not done in a way that this well ever did put up big numbers.

Great point. 8 years ago. Producing a horizontal at less than 2000'. I personally think a horizontal Clinton Oil well will be a challenge, but find a good Clinton gas field and that could be prolific.
