Give Credit Where Credit Is Due -- EOG, Two Great Wells -- Bakken, North Dakota, USA

Over the past year I have given EOG a lot of grief for reporting wells with less-than-impressive IPs (just one data point, yes, I know).

But elsewhere some folks were talking about production in "35/36-151-91."

Those are sections 35 and 36 in T151N-91W, Parshall oil field, Williston Basin, North Dakota.

According to the NDIC GIS server, there are only three wells in these two sections (and all of them are spudded in section 36). I originally thought all of them ran under the river, but I was wrong:
  • 18827, 732, EOG, Liberty 10-36H, Parshall, t2/11; cum 182K 6/12;
  • 18828, 1,066, EOG, Liberty LR 16-36H, Parshall; this is a shorter short lateral running northwest to southeast; t2/11; cum 201K 6/12;
  • 19919, 1,648, EOG, Liberty LR 21-36H, Parshall, t7/11; cum 197K 6/12;
The "LR" designation for #18828 is confusing; one almost wonders if plans for the well were changed after the permit was granted.  I thought "LR" stood for long lateral under the river, but this is a shorter-than-usual short lateral running away from the river. (Of course, with changing channel, or with flooding, the horizontal may actually be under water at times.)

2-2011157500

These two wells, to date, after just three months, have produced 99,356 bbls of oil, and at $50/bbl --> $5 million. At $75/bbl --> $7.5 million.

No precipitous drop in production after the first month which is common for Bakken wells, but I assume we will see the typical Bakken decline over the next six months or so. But still, two very nice wells, and a third being drilled.

Note the nomenclature of the wells.

  1. 18828&19919 Go West under the river out to the west edge of Section 34. 18827 Goes diagonally from the NW corner to SE corner of S 36. All in the Middle Bakken.

  2. Yes, the "hint" is "LR": which I believe designates super-long horizontal, longer than a standard long horizontal. "LR" long under the river?

  3. I just pulled up the well files, they are mapped out in the .pdfs

    You are probably right about the little codes though. Each operator seems to have their own way of doing things. The one thing I've noticed with EOG is if it is a ThreeForks well it will have a 3 digit number. Whiting is really specific, they indicate if its a TF well, If it crosses a section line, if it is a wing well. There seems to be no standard.

  4. It's really just a "cocktail hour" trivia game (guessing at the codes) but it's fun to play. Thank you for taking the time to comment.

  5. I work for a company that does a LOT of work relating to North Dakota / Bakken etc.
    I visit this site regularly and appreciate it.

  6. Thank you for your kind comments.

    I wish I could keep up with all the activity in the Basin.

    I honestly think that no one can visualize how busy this area get over the next few years, but seven to nine new motels/hotels in Williston should provide some idea.

    Again, I am glad you enjoy the site. Good luck in all your endeavors. Drive safely.
