Random Update Of A Zavanna Gust Well in Long Creek, April 20, 2018

Updates

April 23, 2018: a reader with an interest in this area writes:
Well number 19981, the jump in production was after fracking Gust wells 28885 and 28886.

In my view, Zavanna has used the Nelson and Gust wells to test Middle Bakken and TFH combinations, the Nelson 26776 and Nelson 26777 are TFH wells and the old 20085 Middle Bakken. 28885 is a TFH and 28886 is a Middle Bakken.

The Nelsons are fracked with 35 stages. Gust with 50 stages. Some has a GL (gas lift); others AL and one still F.

A Zavanna testbed?
I think the reader is exactly correct. Operators are testing completion strategies on newer wells, taking offset wells into consideration. Also, don't forget the microseismic array across the Bakken.

Wow, this is quite remarkable, and why I love to blog. I already noted this well some time ago -- and predicted they were going to be huge wells. See this post.

This page will not be updated; the wells are followed at the link above.

Look at the recent production profile for this well:
  • 19981, 1,003, Zavanna, Gust 2-11 1H, Long Creek, t3/12; cum 455K 2/18, partial production profile:
There is no evidence this well was re-fracked (FracFocus or sundry form). However, a sundry form said a work-over was accomplished on/about October, 2016: MIRU workover rig; pull GLA; perform cleanout; install GLA; RDMO workover rig; return to production 10/3/16.

This appears to be simply the result of a work-over. This is quite fascinating. Earlier today, for newbies, I posted the "life" of a Bakken well. A little over six years old, almost 500K and one workover. Pretty exciting.
