Anyone want to guess why?  Drum roll: two (2) stimulation stages; "skip 1, 3, and 4" -- only frack stages 2 and 5 using 20/40 Teng/Fel; 350K lbs proppant (for newbies: the "norm" -- 24+ stages; 2 million + pounds of proppant)

This supports a "private theory" of mine that I have not posted. Maybe time to post that "theory."

[Update: don't ask; I've long forgotten what that "private theory" was. No one asked at the time, so I must have lost interest. -- February 25, 2017.]

Now, for comparison, let's look at:
  • 19587, 2,665, Rimrock/KOG, Skunk Creek 12-10-11-9H, South Fork;  t10/11; cum 367K 3/19; off line as of3/19;
Yup, there it is: 30 stages; 4.3 million pounds of proppant (20/40 ISP)
