Random Look At A Bakken Well -- Delay In Production Following Fracking / Testing -- December 11, 2014

I'm sure there are simple explanations for all these things, but when I come across something like this, it certainly suggests I know less than 1% (or even much less) of everything that is occurring in the Bakken.

Take a look at this well:
  • 20815, 325, CLR, Lindell 3-10H, Stoneview, Bakken, 4-section spacing; Stoneview, 30 stages, 3.0 million lbs sand/ceramic; gas maxed at 945 units, t3/12; cum 110K 10/14;
It was tested March 25, 2012.

It was stimulated (fracked) several months earlier, December 18, 2011.

One would assume that it would have some pretty good production in the first month following fracking; and certainly some great production the first month after testing.

But look at the production profile for this well for the first twelve months:

BAKKEN10-20123170266832676920298202980
BAKKEN9-20123088699049724920320203200
BAKKEN8-2012311074110893734314464144640
BAKKEN7-2012311113411510698111482114820
BAKKEN6-201227128081182210298122651224520
BAKKEN5-20120000000
BAKKEN4-20121330273073
BAKKEN3-201210048000
BAKKEN2-20120000000
BAKKEN1-20120000000
BAKKEN12-20110000000
BAKKEN11-20110000000

So, this well was fracked in December, and had no production for the next several months. Nada, zilch, zero.

Even after it was tested in March, there was almost no production; in fact, in May, two months later, there was again absolutely no production, not even one bbl.

But, I guess on June 3, 2012, or thereabouts, they opened the spigot, and lo and behold, almost 13,000 bbls of bubbling crude over the next 27 days.

By the way, this is an "old" well by Bakken standards, spud back in 2011, and yet look at the spacing: 2560-acre spacing. I've always thought 2560-acre spacing was fairly recent.
