Pemit 14154, CLR, Southwest North Dakota

Well, this is sort of interesting in light of all the discussion regarding the Tyler formation. It's probably nothing, but then again, who knows?

In southwest North Dakota, in Bowman County, and in Slope County, there are two active rigs according to NDIC GIS map server. They are both CLR's.

One is particularly interesting, the one in Slope County, just across the county line from Bowman County.

The rig sits on a well that is currently shown as active and producing, with a status date of October 4, 1997 (thirteen years ago, or so), file number 14154, 19-133-106, Flor 24-19RH.  A work-over rig? I don't know enough about the industry to know whether the GIS map server includes work-over rigs.

Notice the interesting designation for this well: "RH."  The "H" designates "horizontal, but I don't know what the "R" designates. There are also several wells in this field that have an "F" designation (no "H" at all); I also have no idea what the "F" stands for. 

It will be interesting to see what CLR is up to. Interesting enough I may have to subscribe to NDIC's "Basic Subscription," $50/year. We'll see.

By the way, CLR has another confidential file just 750 feet northwest of Flor 24-19RH: Flor 24-19NH, file number 19862.

UPDATE: see comment below that explains much of this. Neither the Bakken nor the Three Forks formations are in play here. These are Red River wells. According to first comment below, the well in question is an injection well. I would assume the "R" designation means Red River. I still don't know what the "F" designation means.

  1. Continentals development in the Red River B of Bowman and Slope Counties has been to alternate injection wells with production wells.

    If you zoom in far enough you can see a light diagonal line going through the well head of 15353 just to the north and 15328 just to the south of 14154. The line designates injection wells. Click on legend of the GIS map to see designation.

    There are two new permits 19862 & 19507 that would be spaced between the well you are talking about the two I just mentioned.

    I would think the plans that Continental has if they are being consistent in their development would be to turn the 14154 into an injection well then drill the other two wells as production wells in the Red River B.

    Im pretty sure Cedar Hills and surrounding fields had injection wells from the get go to make them more productive/cost effective.

    If you scan the area close up on the GIS map you will see that probably 1/2 the wells are injection wells.

    What I wonder is if Continental will eventually take the same approach with the Three Forks, Middle Bakken, and possibly the Lodgepole as their new developments mature. Can you imagine 1280 spacing units with 12 production wells and 12 injection wells? They claim with current spacing there is no communication between wells. To do injection wells as secondary recovery the wells will have to be close enough together to communicate.

  2. I am not knowledgeable enough about the oil industry to have seen this, but I am a bit embarrassed nonetheless: I was recently given a tour of this area and the injection wells were pointed out to me.

    I wish I could do more or say more than just a simple "thank you" for your comment.

    You have provided a lot of folks some great insight. Thank you.

    With regard to whether the wells communicate: time will tell.

    12+12=1280 -- almost seems a bit poetic.
