See attached jpg of Rex Harvey 3H.  This well is in Penn Township Butler County, Pa.  The well pad location is behind the Gumto Greenhouse on Meridian Road.  This well is producing at somewhat less than double the output of nearby Marcellus only wells.

  Yes, my lease is strata-specific. Wells drilled to tap other strata are theoretically feasible. But I'm not holding my breath waiting for it to happen. My grandchildren may benefit some day.



Thinking and considering your lease to be 'strata specific' and also thinking that the lateral / horizontal traverses your Point Pleasant member of the Utica (which is probably no more than 100' thick and at the base of your Utica strata (right atop your Lexington / Trenton strata) and considering the fracture radiates outward from the lateral 250' to 500' - that the lateral is probably draining the Utica Point Pleasant and a portion of the Lexington / Trenton - correct way to look at it ? ? One (1) lateral draining two (2) strata (since the Point Pleasant is considered a 'member' (I guess) and really only portion of the Utica.

? ?


To be honest, I cannot recall the exact language of the Pugh clauses in my lease. I'm out of town right now (in San Diego, 75 degrees, sunshine) and will re-read the language when I return next week.



Write when you can.

Standing by.

Thanks for the info.


If you google TAML oil well whipstock, you can see a bunch of graphics and some videos.
In 2011, there's an online history recounting via drilling

There were actually several multi laterals in the Bakken in the early years.,dual and triple laterals coming off a single vertical and targeting the Middle Bench.
Apparently the production was not sufficient to continue down that path.

Visited your reference Coffeeguyzz.

Amazing processes and tools described there.

Thank you for pointing us to it.

Every land / mineral owner / lessor should visit it and see what's cookin' in the field.

Amazing - thank you again.

Thank you Brian for all the same reasons ! 

All very enlightening.

Best Regards,



A year ago, the West Virginia University folks published a 200 page analysis of the Utica.
It is EXTREMELY detailed and 'rock wonky', but it is the most current, authoritative source for just what you all have under your feet back there. (Hint, a whole lot).
Last week, the Ohio DNR folks published "Mapping Source ...Devonian Shale ... Southeastern Ohio".
Wonky again, but LOTS of hydrocarbons at shallower depth.
Another PDF proposing multi laterals from 2013 " Multilateral Wells in SE Ohio".
Guys who wrote it sure weren't gonna pay for the drilling.

As far as well spacing, Rice just said they were going to increase distance between laterals to 1,000'. They, along with everyone else, were inching as close to 500' spacing. (The successful Blue Thunder wells are 500'apart).
The other shale plays are all different and evolving.
The Eagle Ford operators are actually spacing only 150' horizontally and 100' vertically in that thick formation.
One of the HUGE advances is the recent control of the (horizontal) frac half length so the laterals are now spaced more closely.

As far as surface separation on the pads, it's only about 50' as this enables the drill rig to 'walk' from one well to another in just a few hours time.

Noticing some (what I perceive to be minor) variance between the West Virginia University Study and ODNR's.

For one thing, the WVU Study appears to plot the Utica a few hundred feet shallower than does ODNR's.

Hey Phil, 

Very interesting. Sorry Mike I think it is possible.

I find it curious how close vertically they are. Seems almost close enough that fracking one might be enough for other, or fracking both sorta "super fracks" them.  What is the horizontal separation?

Don't know the mechanics of it but it would seem to me that you may be able to put almost as many horizontals off 1 vertical as you want.  May have to temporarily plug and unplug.

Something new all the time.



The Marcellus and the Burkett look to be about 200 feet apart vertically.  Some geologists believe that the Burkett and Marcellus should be produced together if the Burkett is to be produced at all.  At the Rex Baillie Trust well site in Jackson Township, Butler County, PA (behind the Evans City Reservoir) Rex stacked two Marcellus wells right above two Burkett wells.  They were four separate wells not two horizontals from one vertical as is the case with the Harvey well.  That well pad has been a good one.


The Harvey Unit 1H is a 100% Marcellus only well with one lateral that targets the Marcellus formation.


The Harvey 1H (019-22376) was not drilled according to DEP records.  DEP says that 3H and 5H were drilled.  The JPG I posted above was from the Harvey 1H well plat.  I have the well plat for the 3H and it shows the same dual lateral configuration.

PA DEP site shows 3H (019-22377) and 5H (019-22378) as being in production.  There could be some confusion in numbering at DEP but I know that only two wells are producing.

It is very possible that the dual lateral configuration was not carried out and they just drilled the Marcellus, since I'm in the Harvey unit I guess that I could call someone and they would answer my question.  If it is a Marcellus only well, they drilled a very good one.
