For Newbies -- August 20, 2017 -- One Of The Peculiarities Of The Bakken

There are now enough wells drilled throughout the Bakken that one can do this:
  • find a recently fracked Bakken well that has a huge initial production
  • go to the NDIC map and find a horizontal well parallel to the recently fracked Bakken well
  • check FracFocus to see if the older Bakken well was re-fracked
So, let's do that.

These two wells were recently fracked by Oasis and will come off the confidential list this week:

32241, see below, Oasis, Forland 5198 41-33 3B, Siverston:

Let's check a nearby Bakken well that was fracked some time ago. In this case,
  • 21657, 1,844, Oasis, Forland 28-33H, Siverston, t3/12; cum 456K 5/19;
There is no report at FracFocus to suggest this well was ever fracked after the original frack in 2012. So what was the production profile for this well over the past 12 months?

In this case, this well was producing about 2,000 bbls / month; it was taken off-line for five to six months, and then brought back on line, and produced about 22,000 bbls in one month -- equal to what this well would have produced in one year. 

The graphic:



Just one of the peculiarities of the Bakken, I guess. Take a Bakken well off-line for a couple of months, in this case five or six months, and watch production jump 10-fold. Rinse. Repeat.
