Whiting Gets The Peery State (#16463) Back Into Production -- March 30, 2018

The well:

• 16463, 1,081, Whiting, Peery State 11-25H, Sanish, t5/0; 385K as of 9/15; now 397K 1/8; very little production after 2014; ... until mid-2017

I had not updated this well since September, 2015. That's about 2.5 years ago. I've gone through all the 16XXX wells, the 17XXX wells, the 18XXX wells, and am working through the 19XXX wells -- and there are thousands of Bakken wells drilled between 2007 and 2011 that are "lousy" wells.

So, going through all these thousands of wells, here's what can happen in the Bakken, something we don't see in conventional plays.

In October, 2013, for all practical purposes this well was taken off-line; occasionally there was some production.

Here's an example of the production in CY 2014:

BAKKEN	12-2014	1	3	3	1	21	19	0
BAKKEN	11-2014	4	2	3	2	8	0	0
BAKKEN	10-2014	31	78	86	42	66	4	0
BAKKEN	9-2014	30	713	711	142	450	260	131
BAKKEN	8-2014	4	258	251	55	237	129	101
BAKKEN	7-2014	0	0	0	0	0	0	0
BAKKEN	6-2014	0	0	0	0	0	0	0
BAKKEN	5-2014	0	0	0	0	0	0	0
BAKKEN	4-2014	0	0	0	0	0	0	0
BAKKEN	3-2014	0	0	0	0	0	0	0
BAKKEN	2-2014	0	0	0	0	0	0	0
BAKKEN	1-2014	0	0	0	0	0	0	0

Here's an example of the production from this well in CY 2016:

BAKKEN	12-2016	0	0	1	0	0	0	0
BAKKEN	11-2016	3	10	9	47	4	0	0
BAKKEN	10-2016	0	0	0	0	0	0	0
BAKKEN	9-2016	0	0	0	0	0	0	0
BAKKEN	8-2016	0	0	0	0	0	0	0
BAKKEN	7-2016	0	0	0	0	0	0	0
BAKKEN	6-2016	0	0	0	0	0	0	0
BAKKEN	5-2016	0	0	0	0	0	0	0
BAKKEN	4-2016	1	4	4	20	2	0	0
BAKKEN	3-2016	1	1	1	8	2	0	0
BAKKEN	2-2016	1	0	0	17	2	0	0
BAKKEN	1-2016	1	1	1	9	2	0	0

Maybe someone smarter than I can see the incredible difference in production between 2015 and 2016. I can't.

But prior to 2014, it was a pretty good well:

BAKKEN	9-2013	25	1143	1246	55	2242	2094	100
BAKKEN	8-2013	31	2466	2391	171	2782	2649	71
BAKKEN	7-2013	31	2576	2692	277	2980	2918	0
BAKKEN	6-2013	25	2830	2838	346	2053	2007	0
BAKKEN	5-2013	31	3480	3350	231	3353	3291	0
BAKKEN	4-2013	30	3637	3703	182	3418	3358	0

So, pretty much a dead well after 2015? Apparently not.

Look at the production starting in June, 2017:

Pool	Date	Days	BBLS Oil	Runs	BBLS Water	MCF Prod	MCF Sold	Vent/Flare
BAKKEN	1-2018	31	1502	1665	619	2127	2065	0
BAKKEN	12-2017	31	1504	1342	846	2747	2685	0
BAKKEN	11-2017	30	1440	1430	1048	2712	2652	0
BAKKEN	10-2017	31	1464	1461	1137	2745	2683	0
BAKKEN	9-2017	30	1473	1481	1681	2511	2451	0
BAKKEN	8-2017	31	1759	1786	1374	2159	2097	0
BAKKEN	7-2017	31	1626	1594	1354	1659	1597	0
BAKKEN	6-2017	27	1080	1066	2539	1162	1108	0

So, what happened?

FracFocus: no evidence that this well has been re-fracked. No evidence that this has anything to do with neighboring wells.

But, then there's a sundry formed received by the NDIC, June 2, 2017, for work completed May 23 2017: "Due to a tight spot found at ~8,180' in the HCL-80 casing, Whiting Petroleum set a 5.5" permanent packer at 8700' with 2500' of 5.5", 23 ppf scab liner above it with liner top packer."

An attached19-page diagram suggests work was begun April 11, 2017. The total AFE was $950,000. With the work-over, how is the well doing?

This well, #16463, was a tri-lateral horizontal. See graphic below. None of the neighboring wells were taken off-line while this well was being re-worked.
