The Bakken -- March 21, 2021

Note: in a long note like this there will be typographical and content errors. I often see things that don't exist. If this is important to you, go to the source. I am inappropriately exuberant about the Bakken. Facts and comments will be interspersed. It may be difficult to recognize the comments or separate them from the facts. This post was not proofread prior to final posting. I may or may not proofread it later. The mainstream media seldom, if ever, reports some of the observations that are made in this post.

In the graphics below,

  • in the first graphic, a three-well pad; an old well and two new wells; one assumes the two new wells on confidential list will run to the northwest, parallel to the older well;
  • in the second graphic, the entire section of interest; note four "older" wells running to the south; no big deal; except ....
  • in the third graphic, note that two horizontals are likely to cut right across these south-running horizontals; one already does;

Production, below the graphics, note the production profile of the four south-running wells; things to note:

  • the four wells running south were taken off line in the spring of 2020; they were probably taken off line while the wells from the southeast (still confidential) were being fracked;
  • the oldest well, #17668, was also taken off line during this same time frame and was recently taken off line again in late 2020; it might be coming back on line; it produced for three days in 1/21;
  • three of the fourth south-running horizontals, almost eighteen months old now are still flowing, without a pump (it should be noted that paperwork often lags what is going on in the field);
  • two of the wells, not yet eighteen months old, have already reach 500K bbls crude oil cumulative;
  • the oldest well under consideration, #17668, has produced 668K bbls over its lifetime but there's more to it:
    • his well had produced 505K bbls of crude oil from 2009 to 2019, ten years. And then, between late 2019 and very, very early 2021 (seventeen months), this well produced another 163K bbls of crude oil -- a well that is now in its twelfth year of production. 
    • this is not an unusual phenomenon in the Bakken and is clearly something unique in unconventional oil; I don't follow other unconventional plays, so I do not know if this phenomenon is seen elsewhere; if not, then it's unique to the Bakken

Other comments:

  • Petro-Hunt "owns" the Charlson oil field;
  • like the Bailey oil field, the Charlson seems favorable for re-fracks and the halo effect; this does not seem to be true of all fields in the Bakken;
  • there is very little talk in the mainstream press about the phenomenon of a huge production jumps in Bakken wells even after ten years of production;

From the north:

  • 34658, 1,050, Petro-Hunt USA 153-95-3A-10-4H, Charlson, F, t8/19; cum 240K 1/21;
  • 34657, 1,328, Petro-Hunt USA 153-95-3B-10-3H, Charlson, F, t8/19; cum 510K 1/21;
  • 34656, 1,131, Petro-Hunt USA 153-95-3B-10-2H, Charlson, AL, t8/19; cum 217K 1/21;
  • 34655, 1,748, Petro-Hunt USA 153-95-33-10-1H, Charlson, F, t8/19; cum 495K 1/21;

This well goes over 500,000 bbls cumulative, and the well does it with a flourish:

  • 17668, 1,163, Petro-Hunt, USA 3D-4-4H, Charlson, t9/09; cum 505K 8/19; cum 668K 1/21;

This well was first drilled in 2009, ten years ago.

Note: the above entry does not have an error. I am initiating something new on the blog. I will start retaining prior cumulative data when there is a point to be made. So, in the example immediately above, this well had produced 505K bbls of crude oil from 2009 to 2019, ten years. And then, between late 2019 and very, very early 2021 (seventeen months), this well produced another 163K bbls of crude oil -- a well that is now in its twelfth year of production. 

The two wells that will parallel #17688:

  • 34654, conf, Petro-Hunt USA 153-95-3D-10-6H, Charlson, producing, 1/21;
  • 34653, conf, Petro-Hunt USA 153-95-3D-10-5H, Charlson, nice well, 1/21; 6K after first 12 days;
