Case Study -- Bakken Well -- Bruin -- Fort Berthold -- McGregory Buttes -- #20879

This page won't be updated. See this note for background. This is what makes unconventional drilling / shale oil / tight oil so exciting.

As I've mentioned many times before, over the course of a Bakken well's lifetime -- 35 years -- the well will see work-over rigs; will undergo mini-re-fracks; and, major re-fracks. Existing wells will be impacted by neighboring wells. The wells will not follow a simple/conventional "depletion" rate curve.

Here's another example.
I followed this well for quite awhile some time and then removed it from the list of wells that needed to be followed.

The well:

• 20879, 2,709, Bruin/HRC, Fort Berthold 147-94-1A-12-2H, McGregory Buttes, t1/14; cum 486K 10/18; back off-line 9/18;

I quit following this well back in 2014 after the successful frack. Since then, it has been an outstanding well, with the typical Bakken decline.

Now I see that this well is back off line. Full production profile here.

There is a lot of activity in this area, as one can see in the graphic below.

Other wells of interest in the graphic:

• 32503, off line as of 10/18; t12/16; cum 295K 9/18;
• 32505, production jump form 3,000 bbls/month (9/18) to 7,000 bbls/month (10/18) but it looks like it might have been off-line much of 8/18 and 9/18; and now back on line for the full month; t12/16; cum 249K 10/18;
• 30680, 823, Bruin, Fort Berthold 147-94-1A-12-9H, McGregory Buttes, t8/15; cum 348K 8/18;
