Random Update of CLR's Development of the Three Forks Formation in The Killdeer Area: Provided By a Reader; Did Stimulating a New Well Increase Production at a Neighboring Well?

A reader sent the following information in as a comment. Some folks don't read the comments, but this is an excellent piece of work and needs broader reader exposure, so I am re-posting it here.

One of the reasons it has been difficult to follow development of the Three Forks is because the names of the well may not indicate it is a Three Forks well, though that seems to be changing. (Whiting does a great job with the "TF" and "PH" designation, for example.) The next challenge will be identifying 2nd, 3rd, and 4th benches of the Three Forks. I don't know if CLR's goal to re-define the stratigraphic limits of the Bakken Pool will get to that degree of granularity; if it did, the information might show up in the file reports. Otherwise, our only recourse may be the corporate presentations. 

The following: Continental's effort to develop the TF in the Killdeer area. From west of Killdeer (Roadrunner) to the North Killdeer Mountains a swath about 4 or 5 miles wide the reader found 26 wells producing from the TF.

Just short of 3 million barrels.

On a side note go to the Mittlestat 1-20H (17201) well file and you can see that for 7 months prior to June the well did not exceed 2,000 barrels per month. 30 days in June 1,771. Then,  wow: 31 days in July 12,548; then 31 days in August 6,997.

No indication of any down time for clean out or refrac therefore the only thing it appears to me going on the area was the completion of the (21569) Mittlestat 2-20H which comes off confidential this week. Somehow the frac job from the second well must have stimulated the first well. Without plugging it from migrating sand.

I am now curious to see if the second well might be a lower bench TF well. Across the gravel road to the south is the Bice 1-29H and the 2-29H. The second Bice well was drilled into the MB and maybe had some impact on production from the first but I don't think very much, not 6- or 7-fold. It was shut down during the completion and frac of Bice 2 to do some testing for communication between formations.

  1. I took a look at the well file for #21584. Nearly 30,00 barrels production in August alone!!! That's an incredible number!!

    1. You are correct; some of these wells are incredible. Also, some of these wells do not have a horrendous decline that is generally so typical.

      It was very nice that someone took the time to sort out the TF wells in the Killdeer area and then shared their results.
