Trenton limestone potential in Ohio?

While doing research on the utica I have discovered the Trenton limestone that is below the utica. This was the most important oil bearing formation at one time in Ohio and actually started the oil industry in the 1800s. My question is: what is the future potential of the trenton limestone using horizontal drilling? We should be looking into this as a possible new source of income from leasing and royalties.

  I agree on that. In a question I asked an attorney for a land group they created  I said looks like you want to give everything, his response was they will not take a lease if they don'y get it. Hmm this attorney is supposed to be negotiating in the future for the landowners and he knows this already? I RED FLAG THIS!

they drilled into the beekman formation, just under the trenton blackriver, in springboro pa. a vertical well.  400 barrels of oil per day.   end of 2011.

At 400 barrels a day.  What would the royaltys be?  Would there just be a few or just one that recives payment? (vertical)  And how deep is this formation? Thanks!

Gary,

That's a great well. Who is the operator?

Is this Crawford or Erie Co?

gayden, enervest is in that area. that isn't the only good well in that area. just hope it spreads south.crawford county.

Many of the permits in Columbiana County are for the Trenton Black River formation.

Interesting, but are those permits for vertical only or horizontal?

Horizontal I believe.  ODNR no longer shows vertical permits on their site so all permits are for horizontal. 

All are listed as Trenton Black River, Utica- Trenton or Point Pleasant as the targeted formations.

I BELIEVE the Trenton/Black River plays are conventional (I'll wait to be corrected though).

Big difference between unconventional (shale play) and conventional - for a conventional play, the reservoir has sufficient porosity that you need to have a trap, usually a geologic structural feature so the bouyant hydrocarbon rises to the top of the structure and is trapped (think an upside down bowl).

On the other hand, unconventional reservoirs like the Utica and Marcellus, the rock is sufficiently tight, that is the porosity is low, it does not allow hydrocarbons to easily migrate and thus is essentially trapped right where it is produced.

What this means from a production standpoint, for a conventional play the only place you drill is on the structure.  For unconventionals, you have a vast region which can still be productive.

The attached plats for wells in beaver county, pa extend into the trenton and black river (I borrowed them from a post craig had made some time ago). Any significance that CHK drilled down to these formations when they were targeting utica?

No significance - notice, they only tag those units on the vertical pilot hole.  This is done to make sure you have fully penetrated your target unit and provide enough length of hole to run logs over the region of interest (the tools can be >50' long, so they need to overshoot).  So, in these cases they KNOW the end of the Utica, they plug back and kick off the lateral.

Does anyone know if the landowner groups that have recently leased in Noble or guernsey counties had to give away the trenton along with the utica?
