Random Look At Some New Whiting Activity In The Sanish; Ness And Brown Wells -- January 28, 2020

The four-well pad of interest (note the "chronologic" number:
  • 18244, 3,014, Whiting, Ness 44-21H, Sanish, t1/10; cum 557K 11/19; an incredibly non-descript well that quietly goes over 500K cumulative oil;
  • 37090, loc, Whiting, Ness 44-21-2TFH, Sanish,
  • 37091, ros (January 2020), Whiting, Ness 44-21 2H, Sanish,
  • 37092, drl, Whiting, Ness 44-21-21HU, Sanish, 

  • 20505, 2,868, Whiting, Brown 41-28XH, Sanish, t3/12; cum 409K 11/19;
  • 25728, 892, Whiting, Brown 41-28-2XH, Sanish, t10/13; cum 237K 11/19;

  1. Julia TTT right next door is an exceptional well, drilled right alongside an existing TF well about 4 years ago.

    1. 31622, IP=902, Whiting, Julia TTT 34-22H, STILL FLOWING, no pump according to the scout ticket; t11/15; CUM: 546K bbls oil.

      Yes, a huge well, and just one more example of why I say there is still so much work left to be done in the Bakken.

      Thank you for taking time to write.

  2. Was 18244 well drilled in 2010? Am I reading that right? 37090, 37091,37092 are the new wells? What does los, ros, and drl mean? Any help would be greatly appreciated

  3. Most acronyms are NDIC or other agency acronyms. Some acronyms I use for my own benefit for short-hand.

    LOC: NDIC acronym; "location"; a permit has been issued for this location but nothing else has happened at the site; it is not "confidential."

    ROS: my own acronym to show that a "drilling rig is on site" at the time of the post.

    DRL: an NDIC term that means that the well is on DRL status. It is in the process of being drilled; it is not on the confidential list; it has not yet been fracked.

    CONF: confidential list.

    Yes, #18244 was drilled in late 2009. It was completed/tested in early January, 2010.

    FAQ #1 at this site explains my shorthand. The shorthand will vary but the key data is always there. http://themilliondollarway.blogspot.com/p/faq.html.

    Generally, permits with numbers before 24XXX were from the early days of the Bakken boom. North Dakota is up to permit # 37355.

    Permit numbers for various years, some data here: http://themilliondollarway.blogspot.com/2019/06/random-note-on-number-of-permits-2019.html.

  4. On the NDIC maps:

    black circle, with no line extending: generally a vertical well, completed and producing;
    black circle with line extending from the black circle: a horizontal well, completed and producing;

    an orange circle: a well on confidential status; might be a DUC (drilled to depth but not yet fracked);

    a green, empty circle: drill (DRL) status;

  5. Thank you so much for the quick response and clarification. So is 37090, 37091, & 37092 infill drilling or just drilling on same pad? Thanks!

    1. Almost all drilling in the Bakken is pad drilling. There will initially be one well drilled in a drilling unit (a drilling unit being one section or two sections, generally). That first well will hold the lease by production. The operator will generally come back later, sometimes years later, to drill more wells on that same drilling unit.

      For any number of reasons, they will drill all subsequent wells around that original well on a pad. Originally, pads were two-well pads; then the norm became four-well pads. Now, six-well pads are common; and, we're starting to see 10-well pads.

      I think different folks use the term differently, but generally speaking almost all wells being drilled in the Bakken now are infill or development wells.

      Occasionally, and very, very rarely, we will still see a "wildcat" well.

  6. Thank you for the quick response. So is 37090, 37091 , & 37092 infill wells or just same pad as 18244? Thanks!

    1. It appears that all four wells are on the same pad. #18244 was the original well to hold the lease in that drilling unit. The operator has now come back to drill additional wells which in this case would be considered infill or development wells.

      Note: all my comments/replies are "general" in nature. There are many exceptions, and I sometimes use words as laymen use words, not the "official" way that oilmen use the terms. And even among operators, it seems different folks use some terms differently.

    2. When the Bakken boom began, in general, drilling units were one section (640 acres); one mile x one mile. Very quickly, the "standard" drilling unit/spacing unit became 1280 acres (two section; one mile wide x two miles wide.

      Because horizontals have to be set back from the section lines a lot of oil was "orphaned." For that reason, there are now "overlapping" spacing units, starting at 2560 acres (four sections) so that oil along the section lines can be captured. We are now seeing larger and larger spacing units to capture orphaned oil -- six sections (3840 acres) and 5,120 acres (eight sections) for example.

      The majority of wells being drilled are still middle Bakken wells but more and more operators are drilling just below the middle Bakken to the Three Forks. Originally, there was "just" the Three Forks, which was usually meant to be the "upper" or "first bench" of the Three Forks. In some areas there are one, two, three, or four benches of the Three Forks, not all benches will be economically productive.

      In general, in the better part of the Williston Basin/Bakken, one can expect six to twelve middle Bakken wells, six first bench Three Forks wells, and six or more wells targeting the deeper Three Forks, in a 1280-acre drilling unit. In these better parts of the Bakken, a mineral owner have minerals in any one of those 1280-acres, will "participate in as many as 24 wells, maybe more, perhaps less, but it may be many years before we get to that many wells in these better drilling units.

      Again, "generally speaking."
