Original Post 

This post is not ready for prime time.

It may be deleted later when I find an obvious error or mistake. But for now:

******************************
By the way, there is something going on with the KOG wells. I haven't pulled down the file reports but look at this.

• 18987, 223, KOG, Two Shields Butte 14-21-16-2HS, Heart Butte, t4/11; cum 119K 4/13;
• 21513, 23, KOG, Smokey 3-6-7-14HS, Bully, t2/13; cum 24K 4/13

Those are the WORSE IPs KOG has ever posted, and these are in the best spots in the Bakken.

But KOG is producing:

18987, see above, KOG, Two Shields Butte 14-21-16-2HS:

Date	Oil Runs	MCF Sold
4-2013	29870	6877
3-2013	39636	0
12-2012	75	0

 21513, see above, KOG, Smokey 3-6-7-14HS, Bully:

Date	Oil Runs	MCF Sold
4-2013	11443	19911
3-2013	10894	0

In other words, these are HUGE wells for KOG, and yet their IPs were the worse possible.

It turns out these wells were drilled some time ago, and had lousy IPs. They were taken off-line for two to three months -- no one has said why -- what they were doing during these two months. Prior to taking them off line, they were producing 300 bbls/month.

After coming back on line, they were gushers, to 40,000 bbls/month in one case; and 11,000 bbls/month in the other case.

My hunch is that KOG drilled these wells a long time ago, but never fracked them (for all kinds of reasons) but they reported an IP before the wells were fracked. After fracking, the huge production.

The problem with that theory is that I have never seen an operator report an IP before the Bakken well was fracked. They simply carried it on the books as on DRL status.

I'm hoping the well files show something; if not, I will need Zeits or Filloon or a corporate presentation to explain what is going on.

But from 300 bbls/month to 40,000 bbls/month is absolutely incomprehensible.
