Update

December 18, 2011: went through the list below; looks like six wells have been re-worked/re-fracked

Original Post

Back on October 25, 2009 -- feels like "ages ago" -- I posted:

Energy production in North Dakota can be thought of as a series of three-legged stools:

Energy: oil, natural gas, and coal.
Technology: hz drilling, multi-stage fracking, re-frac.
Formations: Bakken, Three Forks Sanish, Lodgepole.

Brian sent me a nice note today reminding me that that at the 2011 Howard Weil Energy Conference, Marathon Oil (in slide 73 of 95 slides) said they planned to re-frack 18 wells in the Bakken in 2011. 

I don't know what 18 wells MRO selected, but I will put put a few wells on my list to follow-up to see if production has changed six months from now. This is done for my own benefit, so I don't forget.

I have selected about 25 wells, based on information from various sources and for various reasons; again, this is just for my own benefit; I will tag these "follow-up and look at them six months from now, just simply for the fun of it. Don't try to make sense of the list:

• 16758 - 30 -1559; summer of 2012?
• 17140 - 30 - 1290; Dec 11:  production at 1,607, but never taken off-line
• 17693 - 30 - 1368; summer of 2013? re-worked late 2014/early 2015 -- significant jump in May, 2015
• 17876 - 30 - 1196; Dec 11: no evidence of any refracking; update, November, 2017, it looks like it was re-fracked;
