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:
BAKKEN12-2014133121190
BAKKEN11-20144232800
BAKKEN10-2014317886426640

BAKKEN3-20140000000
BAKKEN2-20140000000
BAKKEN1-20140000000

Here's an example of the production from this well in CY 2016:
BAKKEN12-20160010000
BAKKEN11-2016310947400
BAKKEN10-20160000000
BAKKEN9-20160000000
BAKKEN8-20160000000
BAKKEN7-20160000000
BAKKEN6-20160000000
BAKKEN5-20160000000
BAKKEN4-201614420200
BAKKEN3-20161118200
BAKKEN2-201610017200
BAKKEN1-20161119200

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:
BAKKEN9-201325114312465522422094100
BAKKEN8-201331246623911712782264971
BAKKEN7-20133125762692277298029180
BAKKEN6-20132528302838346205320070
BAKKEN5-20133134803350231335332910
BAKKEN4-20133036373703182341833580

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

Look at the production starting in June, 2017:

BAKKEN6-201727108010662539116211080

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.
