Slawson's Dual Laterals

Purpose of the blog: to see some innovative drilling by Slawson. Other operators may be doing the same thing, but if so, I've not seen any examples (to the best of my recollection). I've talked before about some of the innovative things Slawson is doing in the Bakken.

Disclaimer: in a long note like this, there will typographical and factual errors. The purpose of the post is to give me an idea of what Slawson is doing in the Bakken. Errors will be corrected when found but errors should not detract from the purpose of the post.

Comment: I particularly enjoyed the common sense solution to a problem encountered by Slawson (see below).

Slawson dual laterals -- transferred White Butte:

• Three White Butte/Slawson Panzer wells.

Screenshot from October 22, 2019 -- Slawson dual-laterals.

29471, 1,423, Wolf 2-4MLH, Big Bend, t3/15; cum 289K 8/19; a good well, not a great well;

• lateral #2, middle Bakken: 17 stages; 1.8 million lbs (no typo); 15,095' measured depth;
• lateral #1, middle Bakken: 21 stages; 3.0 million lbs (no typo); 14,570' measured depth;
  

19993, IA/1,242, no production since 8/18; Hunter 2-8-17H, Big Bend, t11/11; cum 285K 8/18;

• a good well, but off line for the past year, concerning; local oil spill discovered 6/22/19; frack data, middle Bakken, 10/25/11, 28 stages; 2.6 million lbs; open hole;
  

30074, 981 (two sundry forms; see below; 981/238),  Slawson, Howo 2-4-33MLH, Big Bend, t4/15;  cum 521K 7/19;

• huge well; came off line 7/19; remains off line 8/19; 
• lateral 2, IP = 238: middle Bakken, 31 stages; 4.5 million lbs; 4/18/15;
• lateral 1, IP = 981: middle Bakken, 25 stages; 4.7 million lbs; 7/25/16;
• both laterals completed during same time period, March 18, 2015;
• spud date, February 10, 2015
• vertical, big rig, began on/about February 17, 2017
• the curve was begun February 19, 2015, and completed February 21, 2015
• lateral 1: completed March 4
• lateral 2: began, March 8, 2015; completed March 18, 2015, although in the "conclusion," the geologist states the well was completed march 8, 2015 (which makes more sense); challenges with completing the lateral

30540, SI/NC, Slawson, Jeriyote 8-5-32MLH, Big Bend, no production data,

• FracFocus shows the well fracked 10/2/2019 - 10/11/2019; 11.4 million gallons of water (a big frack); 91% water by mass; sand, 8.7% by mass; only one lateral on the initial permit, but a sundry form in autumn, 2018, with a request for an additional lateral;
• lateral 1 BHL: 200' FNL & 1320' FEL, 32-152-92
• lateral 2 BHL: 200' FNL & 2640' FEL, 32-152-92
• so, the "big frack" if divided between two laterals, relatively modest fracks

30763, SI/NC, Slawson, Hunter 5-8-17MLH, Big Bend, no production data, was to be a dual lateral;

• then February 20, 2016, permit was canceled for economic reasons (sundry form); sundry form, August 17, 2018, request for name change to Hunter 5-8-17MLH; 
• then, of all things, a Jun 23, 2019, sundry form, "Slawson is submitting a drill plan change for a 3rd lateral due to technical issues on previous two laterals. Please see attached plan ...." 
  
  
  
  
• to sort this out, I'll wait for the frack data
  

30764, PNC, Slawson, Hunter 10-8-17TF2H, Big Bend,

• sundry form, received October 23, 2014, mentions that #18792 was drilled with a Triple Combo open hole log suite
• sundry form, received February 2, 2016, permit canceled for economic reasons
