Whatever Happened To The Upper Bakken Shale? -- October 9, 2014

This takes us back to a June 16, 2012, posting in which we discussed Slawson targeting the Upper Bakken Shale.

For newbies, it might be advantageous to review the geology being discussed at this post (at the linked post, scroll down to the "geology"). 

 A reader asked "whatever resulted from the Slawson wells that targeted the upper Bakken shale?"

In the linked post above to the June 16, 2012, entry, the Slawson wells were not specifically identified.

Going to "well search" at NDIC site, there are only two wells that fit that description:
  • #16920, 216, Slawson, Piranha 1-4H, upper Bakken shale, one section, t3/08; cum 105K 8/14;
  • #16401, conf, Slawson, Stingray Federal 1-32H, upper Bakken shale, two sections; t4/07; cum 195K 8/14;
The file reports are incredibly interesting. I had not looked at them until recently. They clearly state the objective was the (upper) Bakken Shale.

Both wells are moderately successful and both wells are still active.

Some things to note:
  • the "Bakken" is not otherwise specified, but the report clearly stated "Bakken shale" or "upper Bakken shale"
  • the earlier well is described as a directional well; the older well, a horizontal well
  • although it's possible I missed it, or did not understand the report, it appears these wells were not fracked
  • despite the low IP (and particularly if they were not fracked), the total production has exceeded 100,000 bbls (though it has taken quite a bit of time)

  1. Not stimulated, flat production, 6' of shale with minimal sideboard contribution multiple vintages, lateral lengths subsequent stimulations and far more than 2
