  1. Any information on XYO (sic; XTO?) putting 8 wells per 1280 acres?

    I spoke to a representative who told me they were already starting to drill 2nd and 3rd wells in the 154-96-6-9 area. I would think that would save 10-15 percent of the well costs since very little movement of the derricks would be required.

    Let me know what you have heard. I noticed this in the upcoming docket hearings.

    1. In the better/best Bakken, they will all get to 8 wells in 1280-acre spacing; fewer wells in the "less good" Bakken.

      And yes, they will save 10 - 15 percent; companies like CLR have mentioned that often. In fact, I think that was mentioned again in the past couple of days. An even bigger savings is in the number of days it takes to drill a well; Reuters says Whiting says it can reach total depth in 15 days, cutting cost of each well by $1.5 million. My hunch is the savings derived from pad drilling will be offset by the new ND regulation regarding waste management which is estimated to cost $400,000 per well.

      Back to your original question. Whiting is drilling the heck out of the Sanish, and will get as close to 8 wells average per 1280-acre spacing unit, and they still aren't there. It will be a long time before XTO and the others even come close to drilling 8 wells on even a few spacing units. I haven't yet found a section in the Sanish where Whiting has got that eighth well, though I could have missed one or two. They have a lot of spacing units with six and seven wells. We will see a lot of spacing units with three and four wells, and Hess/EOG have some six-well pads, but they are the exception right now.

      I check the NDIC GIS map server multiple times each day to get a feeling of who is doing what where.

    2. ....is Mission Canyon near the Tyler or where is it in relation to the Bakken?....I have seen some log files from the 70's from the ESER website that I think drilled into the Madison and were "dry" at the time in this general area.....and I think there are some early 2000's wells in the 138N-99(Sections 6/7/18/19) that are still active....that may be Madison I believe.....I also hear Heath formation and not sure if they all are talking about the same thing?(Mission Canyon vs Madison vs Tyler vs Heath vs etc)....thanks for all your excellent inputs...and very interesting blog!!

    3. At the top of the blog, is a tab called "Geology."

      The very first link provides the information you are interested in.

      It should be noted that the older stratigraphic diagrams often don't show the following (not all layers shown):


      Tyler/Heath
      Madison Group -- Mission Canyon
      Madison Group -- Lodgepole
      False Bakken / Scallion
      Upper Bakken
      Middle Bakken
      Lower Bakken
      Pronghorn Sand
      Three Forks (several units)
      Four (?) Benches of the Lower Three Forks
      Birdbear/Nisku
      Duperow (some refer to this as the Devonian, but Devonian is much more)
      Winnepegosis
      Red River

    4. Was in ND to see family. Went by Decker, Grenze, and Kostenko.

      Nomack 312 is being repaired to move north, not sure what's going on at Decker. It looks like everything is in place but wellhead still closed off. Talked to neighbor on Kostenko, sounds like cracked casing.

      They could not frack earlier this year because of it. Not sure what would happen next if anything. If anybody has input it would appreciated.
