Refracking Wells in the Bakken -- The Bakken, North Dakota, USA

Elsewhere they are talking about refracking wells.

Back in July, 2011, I posted a story about Marathon (MRO) talking about refracking.  I went through the MRO wells and came up with a list of 25 wells that MRO might refrack. I went through that list tonight and came up with six wells, that based on production only, that suggests these wells have been re-worked or refracked:
  • 17753: looks like it was re-fracked/re-worked July 11
  • 17844: looks like it was re-fracked/re-worked May 11
  • 17971: definitely refracked or re-worked
  • 17865: off-line now; being re-worked?
  • 17712: probably refracked/reworked in June 11
  • 17713:  probably refracked/reworked July/Aug 11
Update: March 22, 2022: 

17753: back on line as of August, 2011, and produced 3,100 bbls in June, 2012; t6/09; cum 341K 9/16; At 6/09: 0 stages; 200K proppant; API: 33-025-00851; FracFocus: fracked 8/9 - 9/10/2014; cum 516K 1/22;
17844: only on-line for 9 days in May, 2011, and is now producing 4,000 bbls/month (June, 2012); t9/09; cum 293K 9/16; API: 33-025-00874; FrackFocus: no evidence of being fracked as of 11/26/16; IA/10/20; cum 389K 10/21;
17971: looks like it was off-line for several months last summer (2011), and is now producing 2,500 - 3,000 bbls/month (June, 2012); t9/09; cum 146K 9/16; cum 186K 1/22;
17865: was off-line last autumn (2011) for several months; it is now back on-line and produced more than 6,500 bbls in May, 2012, and almost 5,500 bbls in June, 2012; t259; cum 188K 9/16; API: 33-025-00878; according to FracFocus, fracked 12/11 - 12/11/2011; cum 236K 1/22;
17712: this well was off-line late autumn, 2011; it is now back on line producing in excess of 3,500 bbls/month (June, 2012); t4/09; cum 193K 9/16; API: 33-025-00844; FracFocus, fracked 7/24/2011; cum 245K 1/22;
17713: this well was off-line for almost three months last summer, 2011. Before going off-line it produced 1,800 bbls/month; the first month back on-line, almost 8,000 bbls/ month. It is now pumping 3,500 bbls/month; t4/09; cum 212K 9/16; API: 33-025-00845; at 4/09, 1 stimulation stage 190K proppant; FrackFocus, fracked 8/29/11. Cum 266K 1/22;

    Looking back at dates of posting it looks like maybe Brigham needed to move on the mercer county leases. Don't know how long the leases were written for but 31,000 acres is a lot to do before the end of 2012(lease expires?)if they are producers. Very excited to see what will happen to that BEXP wildcat in Mercer. Fact that they were bought out by Statoil makes it even more interesting.



    (Mercer is already being explored/leased, and there is talk that drilling could begin this year).

    See recent ND State lease auction for starters http://www.land.nd.gov/minerals.htm

    I noticed that Brigham Exploration Company was actively gathering leases in Mercer county during the last mineral auction in February. Given this was an oil & gas company rather than just some speculator would seem encouraging.

    Mercer county also had some reasonably impressive results (around a $100 bonus on average). This would suggest (at least to me) there will be some activity in the next 5 years.

    What is the 'layman' geological explanation for an area, such as western Mercer County, to be outside the eastern assessmetnt area? Do you anticipate these boundary outlines to change in the near future as drilling intensfies in the eastern Dunn county area?

    I checked the GIS map on the ND oil & gas site and it shows one drilling rig on the far east side of Dunn county. If I remember correctly, it was located in T145 R91.

    It looks like there have been several holes drilled in that particualr area recently.

    It will be interesting to see how these perform.

    It turns out that of 14 counties in the Feb. State lease auction, more than half (55%) of the total proceeds went for Mercer County acreage. Also third parties bidding on behalf of some of the larger oil co's.

  4. If leased in 2008, five years takes us to 2013.

    31,000 acres/1,280-acre spacing: 24 wells. They can always farm out their leases to another.

  5. Nice report from Coalinga, CA. Chevron is using 8,000 Solar panel farm to boil water into steam to re-inject oil field there (one of Cali's first and oldest fields). Getting good results so far. Nice combo of a "green" resources helping an immediate need in a proven industry.
