Later, 10:45 p.m. CT: with regard to these staggering numbers, a reader who follows this very closely, wrote:

I just noticed that the top of that MRO TF well was almost 12,000 feet down. 
A few things to consider going forward ...

How thick is this targeted horizon? (Well reports/geologists usually describe the zone's thickness). 
Most likely no additional casing will need to be run, but if depths start to approach 13,000 feet (third/fourth benches?), then higher pressures might necessitate the 'telescoping' of casing. 
This would pose significant additional cost.

The higher formation pressures (found at deeper depths) usually greatly boost overall recoveries of the hydrocarbons. 
This would validate Lynn Helms' long ago statement that the Three Forks production may ultimately surpass that of the Bakken.

Fracturing the rock in the TF must be substantially different than frac'ing  the middle Bakken. 
It would be reasonable to speculate that the operators - now, apparently being led by MRO and CLR - would have held back in pursuing the deeper TF benches as the learning curve would understandably be somewhat financially daunting.

All in all, as these deeper TF wells come online with high production profiles, increasing activity should emerge from other operators.

The XTO Bobcat Federal Wells, Bear Creek

The Bobcat Federal wells are tracked here

 The wells:

  • 34356, 1,305, XTO, Bobcat Federal 14X-35A, Bear Creek, t6/19; cum 470K 6/20; F; for early production: link here
  • 34358, 30 (no typo), XTO, Bobcat Federal 14X-35EXH, Bear Creek, 60 stages, 12.0 million lbs, t5/19; cum 413K 6/20; for early production: link here;

Look at those numbers.

Drilled/completed/tested in May / June of 2019.

A year later: almost 500 million bbls. 

It should be noted that these wells are "extended" long laterals -- three sections long -- which, explains, to some extent, the large amount of water, but, still, a huge amount of water. 

From a reader:

When you first posted the numbers of the XTO wells on August 22, I was struck by several numbers, especially the amount of frac water pumped (830,000 bbls and 585,000 barrels) as well as the exceptionally  long 'flowback/produced water' time frame and amounts recovered.
While I will immediately  follow with a somewhat clumsy, detailed explanation of what XTO has accomplished with these two completions, suffice to say that XTO has developed a way to pump VAST amounts of high pressure fluid underground in a CONTROLLED fashion.

Furthermore, the chemistry of these new fluids/water allows extended underground retention without damaging the formation.  
(In years past, fluid imbibing (softening) of the rock and/or leaving a production-inhibiting coating/skin necessitated a relatively quick removal of the frac fluid in the weeks immediately  following the fracturing). 
This extended period - several months - of maintaining the induced water underground enables the higher hydraulic pressure to push more oil into the wellbore.

Will follow up with explanation of the significance of effectively pumping ~35 million gallons underground.

Seven wells on that pad:

  • 34355, 176, XTO, Bobcat Federal 14X-35E2, Bear Creek, t4/19; cum 169K 7/20;
  • 34356, above,
  • 34357, 10 (no typo), XTO, Bobcat Federal 14X-35AXB, Bear Creek, t5/19; cum 318K 7/20;
  • 34358, above,
  • 34559, 83, XTO, Bobcat Federal 11X-2F2-S, Bear Creek, t5/19; cum 108K 7/20; 20 stages; 4 million lbs; Three Forks 2;
  • 34359, 456, XTO, Bobcat Federal 11X-2A-S, Bear Creek, t4/19; cum 84K 7/20; middle Bakken; 20 stages; 6 million lbs proppant;
  • 34360, 83, XTO, Bobcat Federal 11X-2E-S, Bear Creek, t5/19; cum 45K 7/20; Three Forks, 20 stages, 4 million lbs;

Middle Bakken: Great; First Bench: Better; Second Bench: Best -- March 21, 2020

These three wells were drilled from the same pad by the same company: the deepest well, a Three Forks 2nd bench well, about two months older; used significantly less proppant (14 million lbs vs 21 million lbs) and has produced twice the amount of oil as the middle Bakken well; and almost 60% more than the Three Forks first bench well.

Months of production/BOE cumulative
  • 35108, Three Forks first bench: about 7.75 months; 297,332 boe; best month: 36,639 bo
  • 35080, middle Bakken: exactly 7 months; 243,608 boe; best month: 40,993 bo;
  • 35081, Three Forks, second bench, 9.5 months; 464,916 boe; best month: 69,314 bo;
Disclaimer: in long notes like these, there will be content and typographical errors. If this is important to you, go to the source. 

These three three-lateral Carson Peak wells on this pad swing north to capture most of section 26, and then swing south through section 35, and then terminate near the south line of section 2. 

These are the three Carson Peak wells. Note: the typical length of a "standard" Bakken well is 19,000 - 21,000 (maybe, 22,000) feet. The Morris wells, for example that swing north from this pad measure about 19,000 feet MD.

Note the depths on these wells. The vertical depths (TVDs) vary by less than 40 - 100 feet between middle Bakken wells and Three Forks wells in general across the Bakken. The intervening shale seams are 10 - 30 feet thick; the targeted seams are about 40 feet thick.

Depths:
  • 35080, 2,076, CLR, Carson Peak 7-35H, middle Bakken, Oakdale, t6/19; cum 207K; TD: 25,248 feet
  • 35108, 1,824, CLR, Carson Peak 6-35H1, Three Forks 1st bench, Oakdale, t5/19; cum 252K; TD: 26,152 feet
  • 35081, 3,556, CLR, Carson Peak 6-35H2, Three Forks 2nd bench, Oakdale, t5/19; cum 398K; TD: 25,320 feet;
Frack data:
  • 35080, middle Bakken: 53 stages; 20.62 million lbs
  • 35018, Three Forks, 1st bench: 54 stages; 20.67 million lbs;
  • 35081, Three Forks, 2nd bench: 52 stages; 14.21 million lbs;

  • lateral: completed in three runs;
  • gas readings varied widely; 
    • gas buster brought on line at 12,056' MD after gas readings spiked to nearly 3,000 units
    • again, just after after 15,500' MD, readings often exceeded 3,000 units
    • at 21,500' MD, gas began building again; 3,500 - 4,000 units; faded to around 2,500 - 3,000 units through the last 1,300'  of the well;
  • depths:
    • upper Bakken shale: 11,224' TVD
    • middle Bakken member: 11,238' TVD (forty feet seam)
    • lower Bakken member: 11,278' TVD
    • Three Forks formation top: 11,295' TVD (first bench -- 43 feet seam)
    • internal 1 shale top of the Three Forks: 11,338' TVD (15 feet of shale)
    • Three Forks second bench: 11,353' 
  • ideal target: 15.5' thick; began 6.5' below the internal 1 shale base, extended 22' below the same reference point;
Based on limited data, just as the CDC bases coronavirus case fatality rates on limited data, suggests the second bench Three Forks is going to be twice as good as the middle Bakken, and upwards of 60% better than the first bench.

There Won't Be Any More -- Nothing About The Bakken -- YouTube Fugue -- June 19, 2019

Okay, not quite true.

I said "nothing about the Bakken" in the subject line. But here's a Bakken note.

The XTO Bobcat Federal wells are tracked here. They are still SI/NC (DUCs) but some older wells in the immediate area that were taken off line are now coming back on line suggesting that perhaps the Bobcat Federal wells have been fracked. There is nothing at FracFocus yet. But it gave me a chance to look at this well:
  • 34355, SI/NC, XTO, Bobcat Federal 14X-35E2, 33-025-03404, Bear Creek. This is a Three Forks, second bench well, extended reach (3-section);
From the file report:
  • depths:
    • upper Bakken shale penetrated at 10,996' TVD  (shale seam: 16' thick)
    • middle Bakken penetrated at  11,012' TVD (middle Bakken dolomite: 37' thick)
    • lower Bakken shale penetrated at 11,049' TVD  (shale seam: 19' thick) 
    • Three Forks, first bench, penetrated at 11,068' TVD (dolomite: 39' thick)
    • Three Forks, second bench, penetrated at 11,107' TVD 
  • description:
    • the uppermost section of the second bench is composed of brown shale, tan to light brown shaly dolomite and slighly pink dolomite, which is often referred to as the "Chocolate Shale" 
    • below the "Chocolate Shale / Dolomite" making up the upper third of the second bench, the target zone is composed of light gray-brown to pink, to very light brown dolomite interbedded with multicolored dark gray to blue-gray, to rare green-gry argillaceous dolomite
  • porosity / geology:
    • the best porosity and associated oil staining was observed in a 4' dolomite in the upper half of the target zone approx 2' to 6' high of target center
    • structure maps predicted the formation would stay flat
  • results:
    • the resultant target exposure was approx 80% within the target zone
    • the target up-dip was 0.03 degrees, with formation rising 7' over roughly 15,618' MD
  • total depth: 26,945 feet
  • gas units:
    • highest gas show: 1,190 units
    • average gas: 175 units
    • the lower amounts in gas readings is likely the result of tight porosity and distance from the Bakken source, resulting in gas taking long to infiltrate into the open wellbore
  • drilling:
    • spud date: March 11, 2018
    • re-entry date: May 27, 2018
    • TD: June 13, 2018

The Concert Page

I can count on one hand the number of "big-name" concerts I've attended. The golden age of concerts, at least for me, was in the 1960s and 1970's: Liberace (Vegas); Charlie Rich (southern California); Bob Dylan (San Antonio) -- that was about it. The price of tickets has definitely spoiled the opportunity. Live entertainment -- from Hamilton to Garth Brooks is now for the elite.

I remember going to the Greek Theater, Griffith Park, Los Angeles, on perhaps more than one occasion, but I don't remember the "act."

The best concerts were at the Hostfest in Minot: Charlie Pride; Myron Floren; Williams & Ree; the Ringling 5; Willie Nelson; others I've long forgotten. All "free."

I've seen more musicals in London than concerts in the US. A huge shout-out to the US Air Force for sending us to Europe for thirteen continuous years; four of those years were near London. Then later I returned to northern England for multiple deployments over several years. I never did see The Rocky Horror Picture Show. But I digress.

I was reminded of these things early this morning (see YouTube Fugue): After midnight I start with a random song on YouTube.com which leads me to another and then another. Later, sometimes hours later, I end up somewhere not knowing how I got there. Often I am in a fugue state. I am sure I am not alone.

This morning, shortly after midnight, up popped Charlie Rich:

There Won't Be Any More, Charlie Rich

****************************
On Another Note

I used to enjoy YouTube more but the constant interruption of ads destroys the "mood," for lack of a better word. It breaks the non-drug induced fugue state.

Now, it's Alexa. I love Alexa. Truly amazing. Free, except for the initial $25 outlay or whatever is now for the donut-sized / donut-shaped Echo. For $8 / month, literally every song available.

June 19, 2019: it was noted that some wells in the immediate area are starting to come back on line suggesting that the Bobcat Federal wells have been completed? Nothing at FracFocus yet, so maybe not, but we'll keep watching.

This is one well in in the immediate area that has just returned to production:
  • 18112, 442, XTO, Porcupine Ridge 14-35H, Bear Creek, t4/10; cum 269K 3/20;
Recent production:

If that 1,007 bbls over 7 days can be extrapolated over 30 days, it's going to be quite a well.
