Hess Will Report Three Huge EN-Joyce Wells -- July 11, 2021

Remember how "everyone" says the daughter wells will never do as well as the parent wells. 

Read on. 

The Hess EN-Joyce wells in the Manitou oil field are tracked here

A reader recently alerted me to these wells telling me that they should be huge, and that they should be coming off the confidential list shortly. 

The wells were drilled quickly, and completed quickly; the fracks appear to be "moderate" fracks for the Bakken. 

They remain confidential, but runs are being reported:

  • 37977, conf, Hess, EN-Joyce-LE-156-94-1721H-6, Manitou, from the permit, sections 16/17/20 & 21-156-94; 844 FSL 749 FWL; 33-061-04835; fracked 4/7/21 - 4/11/21; 10.7 million gallons of water; 85.2% water by mass; note four days for the frack; generally, I expect a seven- to 10-day frack; to come off confidential list, 10/24/21;

Parent / Child Wells -- Random Note -- October 11, 2019

Well, look at this.

Regular readers of the blog know that I am inappropriately excited about the "halo" effect -- that jump in production seen in Bakken wells when they are brought back on line after being off line for a few weeks or a few months while neighboring wells are fracked. In some cases (rarely) the "parent" well is off-line for less than a month.

I tag posts discussing this phenomenon as "halo" or "jump in production." I noted the phenomenon almost a decade ago but had not seen validation from a credible source.

[The very first post that was tagged with the halo effect was dated August 19, 2010. Link here: http://themilliondollarway.blogspot.com/2010/08/another-first-for-north-dakota_19.html.]

I did receive a phone call from an analyst at the largest fracking company in the Bakken at that time about six years ago asking me about my observations. The analyst said his company was referring to these as "parent/child" wells. I did not post the specifics of that phone call at that time assuming that some of the information I had been told was proprietary.

[I was in Belmont, MA, when I received the phone call. I was last in Belmont, MA, in 2013: that's why I know that the phone call was at least six years ago.]

I continue to look for validation from credible sources. About a month ago, maybe two or three months ago, I started getting hints of validation from Whiting. I think I have posted some of that, but I can't recall for sure.

Break, break.

It's my observation that the parent / child interaction in the Bakken is "positive." Either there is no effect, a subtle effect, or a huge positive effect, but I have not seen any suggestion that the parent / child interaction is "bad news" in the Bakken.

On the other hand, however, there have been numerous stories in the popular press that this is not the case in other shale plays. There are concerns, particularly in the Permian, that new wells (or "children" wells) are having an adverse effect on older wells ("parent" wells).

Break, break.

Tonight, in the process of looking for something else, I ran across this slide in a recent Whiting presentation.

The link: https://event.webcasts.com/viewer/event.jsp?ei=1260399&tp_key=d761d52d8c.

Slide #9.

Note: "Parent / child well activity [in the Bakken] is positive vs experience in other shale plays."

By the way, that one slide above has many, many other interesting data points.

This Is Absolutely, Positively, Not Happening InThe Bakken -- September 20, 2019

The note below is pretty much complete; there may be some fine tweaking but consider it done.

**************************
Off The Radar Scope: Rigs Do Matter 

This is interesting. I had not thought of this. Because there is so little national news regarding the Bakken and because the Permian is getting all the press, a lot of folks outside the region mistakenly think the Bakken has completely slowed down. An operator looking for capital among investors (east coast, west coast) were surprised to hear that the Bakken was still very, very active. Potential investors were surprised to hear that North Dakota was producing as much oil with 50 - 60 rigs as the state was producing (actually more) than when there were 200 rigs in the Bakken (lousy grammar on my part).

So: the number of rigs does matter when it comes to "demonstrating" activity (and perhaps investor interest). That driller, by the way, suggests that North Dakota would likely produce upwards of 2 million bopd in about three years. If the takeaway capacity was sufficient and the price "right," I think we could be at 2 million bopd now.

In addition, see first comment:
Regarding the linked articles below: Basic concept, not news. Poorly explained (some mistakes).

Also, despite the shift to closer spacing [in the Bakken?], we are still not seeing a dropoff in performance. Obviously there must be other aspects that are improving and the net result is okay, on average.
***********************************
The Note

The world's top oil basin is running out of space -- link here.
Permian "child" wells may cut oil recovery up to 20%, bank says -- Bloomberg.

I'm in a rush right now so I will have to come back to this, but this is so not happening in the Bakken.

First of all, it's an old story regarding the Permian, previously posted on the blog, but both Bloomberg and oilprice make it sound like something new.

From the linked articles:


But whatever. It's not happening in the Bakken.

I don't have the statistical analysis, but I have the anecdotal evidence to make that statement. But Whiting does. Exhibit A:


I don't know the Permian at all. I follow it a little bit and have noted a few things. Most important(ly): it appears unconventional / shale basins are not all alike.

I am inappropriately exuberant about the Bakken, so everything that follows, take with a grain of salt. This is my worldview of the Bakken vs other shale plays, particularly the Eagle Ford and the Permian.

First, I think the Bakken is still going to be the best of the three plays (Bakken, Permian, Eagle Ford) in these categories:
  • effect the Bakken will have on the state economy compared to that of the Permian/Eagle Ford and the Texas economy
  • the amount of money that will be returned to mom-and-pop mineral owners in North Dakota on a per capita basis compared to those in Texas
  • crude oil production per well
Now, with regard to the linked articles above, that "child" wells are a challenge in the Permian. It appears to be quite the opposite in the North Dakota Bakken (I can't speak to the Bakken in Montana and/or Saskatchewan).

It certainly appears the operators have figured out the "Goldilocks" density, although even that will change / improve over time.

It appears that in Tier 1, middle Bakken, six wells in 1280-acre spacing will be the norm.

It appears that in Tier 1, first bench Three Forks, six wells in 1280-acre spacing will also be the norm.

All other tiers and all other Bakken formations, the jury is still out.

To see examples of well density in the Bakken, click on the follow tags:
Years ago I noticed the positive impact that "child" wells had on their parents and on their sibs. I have blogged about that often. An analyst / research student working for Halliburton telephoned me years ago to discuss this with me (he called me; I didn't call him).

I devoted an entire site to these "wells of interest." At the index to that site, one can see all the examples of the positive impact of "child" wells. I think at one time they were called "daughter" wells, but I don't recall for sure. The list of wells has gotten so long, I've pretty much quit doing that. Whether I've "proved" the point or not to others bothers me not at all. I believe what I see.

The Bakken is a bit easier about which to generalize. For the most part, when we talking about the Bakken now (2014 - 2018) we are talking about one formation, about 20 to 40 feet thick, pretty much being fracked about the same by all operators.

I have no clue about the Permian but it's my understanding the unconventional target formations in the Permian are many and they are thick. So, when I see a Bloomberg article with so much generalization it makes me wonder. If I were following the Permian or interested in the Permian I would want to know a lot more specifics.

They used to talk about the Bakken development being like a baseball game and early on we were only in the first inning. No one makes that analogy any more but I would guess we might be in the third inning.

The Permian? Easily the first inning, maybe the bottom of the first inning. But that's it. Based on what little I know about the Permian it sounds like there is a lot to learn. My hunch is that the operators have gone after the absolutely easiest stuff to lift.

Oh, a random note: in the Bloomberg article they talked about "dry" wells in the Permian. That's interesting. Hitting a dry well in the Permian has to be concerning. There are no "dry" wells in the Bakken. We've talked about that before. Yes, some wells are reported as "dry" but that's because of a failure of the well itself, usually a failure in the cementing / casing process. But if the well is completed in the Bakken it will strike oil.

It may not be an "economic" well but we've discussed that also. But it won't be dry.

I have yet to see more than a handful of recent middle Bakken wells abandoned due to low oil production.

MRO Wells In Section 12-150-93 Appear To All Be Back On Line -- Some Huge Wells; Many Reporting Nice Jumps In Production -- August 5, 2019

Newbies: as you look scroll through this post, recall the hand wringing about parent-daughter interference in the Permian. The data below is not atypical for the Bakken, but some fields are much better than others with regard to this phenomenon. Hard to sort out how much has to do with location / oil field, and how much has to do with the operator / completion strategies. Everything I've seen suggests the Bakken operators have a good handle on this issue. Could be wrong.

The well:
  • April 2, 2019: see this post. #33668; #18514; #33431; #23176; and, #21458; and, this post. As of 4/19, older wells still off line; as of 6/19, it appears all wells back on line.

Reason #1 Why I Love To Blog -- Reader Feedback -- Another Well With 50-Fold Increase In Production -- July 26, 2019

I never would have caught this one. A huge "thank you" to the reader who sent this to me.

The well:
  • 17325, 130, Oasis, Thorlaksen 11-14H, 10 stages, 1.35 million lbs, Gros Ventre, t1/09; cum 52K 5/19;
FracFocus: no data suggesting a re-frack. Last NDIC sundry form back in 2013. This well was off line for about one month.

Jump in production: 10,206 bbls over 30 days / 200 bbls / 30 days = 51-fold increase in production.

Recent production, 8,846 bbls over 26 days extrapolates to 10,207 bbls over 30 days:

Production Jumps 55-Fold; An Old CLR Lansing Well In Banks Oil Field -- July 26, 2019

Production jumps 55-fold, 9,000 bbls over 31 days in 12/18, from 163 bbls over 31 days in 8/18 -- just four months later. The well was originally drilled / fracked back in 2010. This well had a 55-fold jump in production when it was already eight years old. And it will continue to produce for 30 more years.

Another well, a bit further to the west, also showed a jump in production, but it was only a 3-fold jump in production.
