Idle Rambling Comparing Two Wells That Were Not All That Great Early On -- Then Their Production Diverged -- February 26, 2017
This is going to be a long note. It is likely to be confusing. It may not be worth the effort. In a long note, there will be factual and typographical errors. If this is important to you, go to the source.
These are two QEP wells very, very close to each other and drilled about the same time. They both had similar births. One died early; one is still alive.
The first QEP well; it may have been killed prematurely; it was never all that good to begin with; its production was about 1,000 bbls of oil/month when it was killed (PA). Monthly production data shortly before it was killed:
Monthly Production Data for well #1:
Notice: that well was killed in May, 2012.
The second well was drilled/completed/tested at almost the very same time, in early 2008.
This is well #2. This was its production between December, 2011, and May, 2012, to compare with the well above:
That well, well #2, was no better, producing about 1,000 bbls of crude oil / month.
But it was allowed to live.
Look at the production since October, 2015, and to the present. Going from around 1,000 bbls of crude oil / month, it jumped to over 8,000 bbls (extrapolated to full 31 days) in October, 2015:
I do not know why well #1 was killed and why well #2 was allowed to live. That's unimportant now.
The question is whether well #1 could have come back as strong as #2 came back after it, too, looked like it was never going to do all that well.

I do not know why well #1 was killed and why well #2 was allowed to live. That's unimportant now.
The question is whether well #1 could have come back as strong as #2 came back after it, too, looked like it was never going to do all that well.
The wells:
- #1, killed: 16959, 971, QEP, Jones 16-14H, Blue Buttes, t6/08; cum 102K 5/12;
- #2, kept alive: 16960, 768, QEP, Jones 4-23H, Blue Buttes, t4/08; cum 156K 12/16;
- #3, in the graphic but not discussed in this post: 17266, 912, QEP, Jones 4-24H, Spotted horn, t1/09; cum 186K 12/16;
Re-Entry; A Second Lateral; Production Profile Of A QEP Well In The Blue Buttes Oil Field -- February 26, 2017
Updates
April 27, 2017: update.
Original Post
- 16652, 434, QEP, Levang 3-22H, Blue Buttes, t6/07; cum 230K 12/16;
- Lateral 1: 368,600 lbs Carboprop open hole, test date, 9/5/2007; Three Forks (short lateral)
- Lateral 2: 98,600 lbs Carboprop open hole, test date, 2/27/2008; middle Bakken -- problems with drilling -- notice in graphic show short the middle Bakken lateral is;
From a sundry form:
The lower / lateral #1 (Three Forks) was IP's separately on 9/5/2007 543 bopd 597 mcfd 218 bwpd. The upper / lateral #2 (middle Bakken) was IP'd separately on 11/14/2007 269 bopd 253 mcfd 37 bwpd. The combined rate was IP's on 2/27/2008 434 bopd 312 mcfd 65 bwpd. The lower lateral is obstructed with proppant and precipitated salt and will be cleaned out and returned to production later in 2008.Production profile for this well:
