Tioga SWEPI Stacked Pays

Just as Shell/SWEPI lists 26 prospective target formations on a single well in Western PA, I suspect they are doing similar testing of about that many formations on a well or wells in Tioga County.

I know of three formations in Tioga County at the Sharrett Well..........all fracked waiting for gathering lines

And along with the multiple stacked pays of Western and Central PA, it's also heartening to hear of industry execs publicly speaking about "100 years of drilling" as they talk about the future here :)  So, when it seems like Shell and others may be taking longer than everyone wants in these developments, it may help to consider that 100 year perspective.

Could be a total of five, Geneseo, Burket, Middlesex, Marcellus & Utica. Not 26.

Please don't continue to prove yourself to be another of the Johnny-Come-Latelys to oil and gas, David.  Shell happens to specifically list the entire 26 on their own documents. Truth be known, there are other portions of Western PA which actually have 30 or more layers beneath them which have proven productive in the past in various locations, or are potentially productive (Which is why Shell lists them as such).

I stand by my comments. Economic strata will come from those areas that have both enough carbon content and total thickness to be make shale drilling worthwhile. I have researched this area for seven years and have never seen any other strata worth looking at. Furthermore there probably is no one well going to get all five of the strata I referenced. While technology may advance someday, these five are known to be worth looking at with current day technology. And to support what I am stating, the highest number of strata producing from one PA well (actually a pad) is currently three, not 26.

I often wonder if people even read some of the posts made on this site, before they write comments or replies. David, When you read the simple two lines which began this thread, where do you see the word "production" ? It isn't even there !! Where do you see any statement in this thread that a single well in PA is "producing" from 26 strata ? Again, not even part of the subject !! This is a post about the various formations which Shell lists and describes as targets on a single well in Western PA. It was meant to stimulate thoughtful consideration for those members and readers who were not already aware of these formations.
If you want to start a thread about the "shale only" economically productive targets which your study indicates Central and Western PA. will be limited to, both now or in the future, then I suggest you begin a thread which has that as the subject. However, I wouldn't recommend adding your seven years of "study" to a resume anytime soon.

21 irrelevant strata, sorry to dismiss them so flippantly but if they are not economic they are just that - irrelevant. And "stacked play" most certainly has a connotation of being economically relevant.

I'm not sure why everyone just can't get along and have an educated conversation regarding this.

Question for David: You've been studying/learning this for 7 years now. How long have you known about the Marcellus, how long have you known about the Utica/Point Pleasant, and how long have you known that there would be 3 landing points for horizontal wells in the Upper Devonian?

Follow up question, how long have you known the estimated gas in place for these formations?

Answer for most us is we have known only as long as the operators released this data, such as after nearly everyone was HBP'ed.

Hence, as an educated guess, I would surmise that Shell testing 26 formations will lead to more economic wells to be drilled in other formations.

Todd,

I doubt it. If you look at the carbon content and total shale thickness, it will clue you in to its potential. Without carbon content, you will not see enough gas & oil potential. I read somewhere along the way that it is a minimum of 50 feet of organically rich zone to get close to economic production. Certainly there will be variations and anomalies, but don't bet the ranch on it. Specifically look for the black shales as they have greater carbon content, the others are not as prospective.

And to answer your question, seven years. There are different strata for upper Devonian that are specific to areas of PA & NY, such as the Rhinestreet. Range has reported good results in that zone, but it will be limited to counties in the West/Central NY & PA The Middlesex, Geneseo, Burket and others will probably be other zones that are productive, specific to certain areas. All three of these have potential in Tioga, but each will not be good everywhere in the county. There are a plethora of maps detailing this, simple google searches will reveal this.

Irrelevant to David Perotto, but not so irrelevant to Shell Oil. How very interesting ! And how very revealing... I can't waste any more of my time.

Is your name Charles or did my ex wife just change her name?
