The case:
- 28293, CLR, Elm Tree-Bakken and/or Antelope-Sanish; i) an overlapping 1280-acre unit, sections 28/33-153-93; two wells; ii) an overlapping 2560-acre unit; sections 28/33-153-93 and sections 1/12-152-94, 22 wells on said overlapping 2560-acre unit; Mountrail and McKenzie counties;
There are two extended long laterals (3-section long horizontals) in this area, running north from the south:
- 35542, TD = 27,066 feet; spacing unit: S1, 2, 11, 12 13 & 14 - T152N R94W; 3840-acre unit; middle Bakken; 67 stages; 16.1 million lbs; 2,587, Bruin, Fort Berthold 152-94-14D-2-13H3; t6/19; cum 233K 11/19;
- 35541, TD= 27,112 feet; spacing unit: S1, 2, 11, 12 13 & 14 - T152N R94W; 3840-acre unit; 67 stages; 13.44 million lbs; Three Forks B1; 2,539, Bruin, Fort Berthold 152-94-14D-2-15H3; t5/19; cum 214K 11/19;
It's a double-wide unit. So really more like 11 wells/unit (normal width). Not that noteworthy. You can see how the river will cause them to have to bend out from one normal unit into the next one, thus the consolidation into a double-wide. That area at the Montrail/McKenzie border is good land too.
ReplyDeleteYou are correct, though I think, if I have the stars aligned correctly, it's a four-section stand-up, but I could be wrong. I often do these quickly and I do make mistakes.
DeleteThere were a number of reasons to post that case as a separate stand-alone and if I have time, or the interest, I will come back to it.
It's four sections, but the standard unit in the Bakken, for several years, has been a 2mi by 1 mi unit (i.e. two sections is normal). This allowed 9800 ft laterals, which became the norm. So a normal 2 by 1 (think domino shape, ask Sophia to show you. ;-) would have 11 long laterals. When they go to 4 sections, that's double the "normal" 2 by 1, making a 2 by 2. Lateral length will stay ~9800 ft (perhaps a little longer, shorter from the curve to get under the river, but nominally 9800). And they will have 22 of them. But it's 11 per normal "domino". Just two dominos side by side.
ReplyDeleteWhat would be interesting is to know the exact plan. Wonder if you can pull the permit or the like? How many wells are going into each layer? Details of the wineracking. And also what contortions necessary to get under the river.
I'm far from an expert but just guessing, would think something like
MB: 5
TF1: 4
TF2: 2
TF3: 0
TF4: 0
That would be for each domino. (So double for the double wide.) It may be slightly different, but would think that's close.
Disregard everything I wrote!
ReplyDeleteI thought it was two dominoes side by side (28, 29, 33, 32), but they are actually in a row (your stars show 12, 1, 33, 28). I guess they will want to use 1 as a pad to send some laterals north into 33 and 28. Maybe it will be more like ll wells in 28 and 33 (headed north). And 11 in 1 and 12 (headed south). The complications with the river make them want to unitize 1 and 33.
Yes, most interesting will be where they will site these wells. Historically, in a stand-up they've sited them in the middle, half going north, half going south. It is noteworthy that there are two extended long laterals (3-section-long laterals) in the immediate area.
