Unfortunately the well file report does not shed any light on what is going on with this well. It is interesting that on June 19, 2009, this spacing unit, Bakken pool only, qualified as "Stripper Well Property." The well produced from a depth greater than 10,000 feet and at a maximum efficient rate, with average daily production from the property 28.3 bopd. (I wondered about this issue back in 2007 when I first started blogging, but intentionally avoided the subject.)
This is an unusual well. It is a vertical well with two horizontal legs, one to the northeast, and one to the southeast. It is located up along the Canadian border.
I do not see any frack report. However, the initial production suggested at least one leg was fracked and the amount of water returned early on suggests at least one leg was fracked.
This is the well. The two arrows point to the two legs of this well:
- 16207, 28, CLR, Zimmerman 1-13H, Border, t11/06; cum 58K 10/13;
It was a very, very unremarkable well. Until recently.
Note: the name of the well has not changed; it does not include the "R" suffix suggesting this is not a re-entry. Was it recently fracked for the first time? I don't know. Hopefully some reader might have some additional background.
The well has produced a cumulative of almost 60,000 bbls since it was drilled back in 2006 (remember, this was before the Parshall discovery in 2007 that marks the beginning of the current Bakken boom). Note the production over the past few months:

The well was spud in August, 2006, with first production in November, 2006. This is the production history early on:

My hunch: either one leg was fracked for the first time, or one or both legs were re-fracked. The big question is the one I avoided back in 2007 and that has to do with "stripper well status."
The Zim - 1 to my understanding had a work over rig this year and a newly completed well targeting the middle bakken was completed in the same zone passing through the zones of the older well - if that makes sense
ReplyDeleteA newly completed well --
Delete"Completed" often means fracking ... it sounds like they fracked one of the two existing horizontals....but beyond my understanding or comfort zone. I appreciate you taking time to write. The work over rig information is very helpful; supports my thesis thatwe are going to start seeing more work over rigs
