Updates
April 16, 2017: there are not eight (8) wells on this pad; in addition to the earlier five, add these three:
33267, SI/NC,
33268, SI/NC,
33269, SI/NC,
December 7, 2015: a similar, but perhaps less dramatic, example can be seen with the QEP Johnson wells in section 4-149-95 (#19680, #25490 - #25493, inclusive), another 5-well pad.
Original Post
- this is a five-well pad; the index well was drilled in 2010; the latest wells in 2014
- the first well was a Three Forks well at a time when most wells being drilled with middle Bakken
- one of the five wells was stimulated twice (it's possible others were but I missed them, although I doubt it)
- note the location of the laterals, and the date of the stimulations
- the index well, the oldest well, is a Three Forks well
- the two wells nearest it, on either side were middle Bakken wells
- the nearest Three Forks well was twice the distance to the index well as the neighboring middle Bakken wells
- the distance between each of the laterals is about 50 feet
- vertical separation between middle Bakken target and Three Forks target was about 150 feet
- the index well was a Helis well, and planning forms and data were in Helis format
- the four newer wells were QEP wells; planning forms and data were in QEP format
- a reminder that Lynn Helms once said that the Three Forks may, in fact, result in better wells than the middle Bakken
- Pythagorean theorem: a^2 + b^2 = c^2

The Wells
Disclaimer: in a long note like this there will be typographical and factual errors. In addition, because I have no formal training or background in the oil and gas industry, there are things I post but do not understand. I may be missing things and may be misinterpreting things. I may be seeing more than there actually is. Do not quote me on any of this. If this stuff is important to you, go to the source.
I posted this yesterday but did not get a chance to look at it more closely; it was late, I was tired.
But this well has an incredible story -- at least the very little we know about it.
There are five wells on this pad. This one runs right down the center and was drilled/completed some time ago. Later, four more wells were drilled/completed, with two wells one each side of the well in question.
Here is the graphic of the 5-well pad:
Abbreviated synopsis of the five wells, when they were tested, which usually occurs soon after they are fracked/completed:
- 18973, 10/25/10; Three Forks target at 10,750 feet; frack data not provided; API 33-053-03156-00-00;
- 28165 [stimulated twice], 10/25/14, middle Bakken stimulated 8/9/15 with 36 stages, 7.7 million lbs, IP, 2,117; middle Bakken stimulated 10/20/14 with 32 stages, 5.4 million lbs, IP, 1,444; middle Bakken target at 10,600 feet
- 28166, 10/23/14, middle Bakken, 33 stages, 8.6 million lbs; target at 10,600 feet.
- 28167, 10/21/14, stimulated the Three Forks, on 10/13/14, 39 stages, 9.9 million lbs; Three Forks target at 10,675 feet
- 28168, 12/10/14, the last sundry form, received June, 2015: QEP plans to re-frack this well; it will run new casing and complete stages 5 - 30 via sliding sleeves and will plug and perf stages 8 - 10 across stages 30 - 39 of the original sliding sleeves). The plug and perf is being done to the stages in which the sliding sleeves have been compromised. Original frack: 36 stages, 4.6 million lbs; middle Bakken target at 10,600 feet.
18973, 2,579, QEP/Helis, State 1-16/21H, Blue Buttes, a Three Forks well, t10/25/2010; cum 567K 10/15; inactive 4/14; looks like it might be back on line as of 10/14; yes, now shown to be active, 12/14; huge jump in production in 12/14; coming back on line after permission to commingle production from multiple wells; large production number could be due to 'mis-allocation' during early commingling; random update, March 20, 2015; random update, May 7, 2015; [note: the scout ticket shows this well in the Blue Buttes oil field, but it is clearly in the Grail oil field, and the scout tickets of its sister wells all show the Grail oil field. A file report has "Grail" typed in and then crossed out in ink and handwritten "Blue Buttes." The geologist's narrative also calls it a "Blue Buttes" well. The very earliest maps show the well clearly in the Grail oil field.
