November, 2019 Hearing Dockets: BR To Request 20 Wells In One 2560-Acre Stand-Up Unit -- Middle Bakken And First Bench Only -- October 25, 2019

From the NDIC, November, 2019, hearing dockets:
  • 28117, BR, Johnson Corner and/or Pershing-Bakken, twenty (20) wells on a 2560-acre unit, section 15/22/27/34 -150-96; McKenzie County
Thinking out loud:
  • currently nine horizontals running north in a 1280-acre unit
  • currently nine horizontals running south in a 1280-acre unit
  • plan for ten more horizontals running north through those two sections: a total of 19 horizontals running north (but the new wells will be spaced at 2560-acre spacing)
  • plan for ten more horizontals running south through those two sections: a total of 19 horizontals running south (but the new wells will be spaced at 2560-acre spacing)
  • these are all middle Bakken and first bench Three Forks wells
  • lower benches of the Three Forks yet to targeted (may or may not happen)
  • many, many ways to look at density
    • one way: 1280 acres / 19 wells = 67 acres (MB and TF1 combined)
    • another way: 1280 acres / 10 wells = 128 acres (MB or TF1 separately)
    • another way: vertical array of 19 horizontals is still less than the 24 or more that some have proposed
    • another way: spacing between horizontals, horizontally: 5280 feet / 10 wells = ~ 500 feet
    • note: about two years into blogging about the Bakken I opined that fracking was effective out to 500 feet radially; something tells me I may be off by a factor of 2 before this is all over
Wells in the graphics (not all wells are in these 1280-acre or 2560-acre spacing units; some of the wells below lie outside these spacing units):

Random Update On An Old Oasis Case Looking To Put Nearly Two Dozen Wells On a 640-Acre Spacing Unit -- August 7, 2019

Spoiler alert: long note, but there is nothing new here. I was simply checking up on an old case. For my benefit only; not of any use to readers. 

Most concerning: of the 12 wells in the drilling unit, it appears only six are producing and only two of them are any good. 

Re-posting part of an earlier note:

Generally speaking, fourteen wells is about the maximum number of wells I've seen in any 1280-acre drilling unit in the Bakken. If any 1280-acre unit has more than fourteen wells, they are few and very far in between.

However, in the August, 2019, NDIC hearing dockets:
Case 27809, Newfield, Siverston-Bakken; 14 wells on each of two existing 1280-acre units; 6/7-150-98; and, 30/31-151-98, McKenzie; already 6 wells on each of these units; this will make it 20 wells in each of these 1280-acre units;
Reminder: that's a case, not a permit.

It's been said that operators won't drill wells in the Bakken if the EUR is not at least one million bbls.
There is an interesting look at dollars / acre at the original post, but I wanted to re-post that note to also note this older case from a post dated January 31, 2014:
From the February, 2014, NDIC hearing docket:
  • 21849, Oasis, Sanish-Bakken, 21 horizontal wells on a 640-acre unit, 4-153-93, Mountrail,
[For newbies: when the drilling started in the Bakken back in 2007, the "word on the street" was one well per section. Folks got excited when they heard talk of four wells in a 1280-acre spacing unit. Now: 21 wells in one section, one 640-acre spacing. Who wudda thought -- just in the past three or four years. I think it's incredible. And that's why the Bakken never ceases to amaze me.]
At that link are the graphics of that area. 

So, what does that section (section 4-153-93) look like today? It has not changed:
  • there are still 12 horizontal wells in that section;
  • it is still spaced at 640 acres; however,
  • section 4 is now part of an overlapping 2560-acre unit

Moving To Twenty Wells In 1280-Acre Drilling Units In The Bakken -- August 6, 2019

Generally speaking, fourteen wells is about the maximum number of wells I've seen in any 1280-acre drilling unit in the Bakken. If any 1280-acre unit has more than fourteen wells, they are few and very far in between.

However, in the August, 2019, NDIC hearing dockets:
Case 27809, Newfield, Siverston-Bakken; 14 wells on each of two existing 1280-acre units; 6/7-150-98; and, 30/31-151-98, McKenzie; already 6 wells on each of these units; this will make it 20 wells in each of these 1280-acre units;
Reminder: that's a case, not a permit.

It's been said that operators won't drill wells in the Bakken if the EUR is not at least one million bbls.

Back of the envelope ciphering:
20 wells x one million bbls (EUR) = 20 million bbls

20 million bbls x $50 / bbl = $1,000,000,000 ($1 billion)

Each well with  infrastructure, etc: $10 million/well (wells are now costing about $6 million to drill/complete).

20 wells x $10 million/well = $200,000,000 ($200 million)

$1 billion - $200 million = $800 million

$800 million / 1280 acres = $625,000 / acre.

Anticipating Another 24-Well Array In A 1280-Acre Drilling Unit -- Lillibridge -- Abraxas -- May 4, 2018

Updates

May 6, 2018: see comments and updates at this post regarding exactly what is meant by "... not to exceed 16 wells..." Without doubt, I am 99.999999% sure that this means that the operator is asking to drill another 16 wells in this drilling unit. I have not gotten a definitive answer from a reliable source, but based on three "data points" it is clear to me that the operator is asking for permission to drill up to 16 additional wells on this drilling unit regardless of what is already there when the operator begins drilling (if the operator, in fact, continues to drill). My three "data points" are subject to debate and/or interpretation so I won't get into them now.


May 5, 2018: see comments regarding this issue. Still no definitive answer to question being raised.

Later, 8:35 pm. CDT: after posting the original note, a reader replied, with a comment and a question. The reader raises a question for which I have no answer. It's a very basic question regarding the NDIC hearings/cases but even after blogging all these years, I'm not sure of the answer.

It has been my impression that readers who have skin in the game -- that is, readers who have mineral rights watch their wells very closely and have a better understanding of what is going on in "their" area than I do. For that reason I defer to readers if I have any doubt regarding my understanding of the issue.

With that in mind, I will leave the original post "as is," but post the comment and the question sent to me by a reader.

First the comment:

In the section to the south of section 20, there are four wells, still on confidential list but their names, Lillibridge, and their siting location, suggest that they will be running north into sections 20/17, also. With the eight Lillibridge wells already in sections 20/17, that means there are already 12 horizontals in this standup drilling unit (one assumes that these four wells are also in the 1280-acre drilling unit, but that is not a given). That's pretty much all factual; we will know for sure when these four wells come off the confidential list.

Now the question: does case #26681 below, in the May, 2018, hearing dockets mean there will be a total of sixteen wells in this 17/20 (1280-acre) drilling unit? If so, that means only four more wells might be drilled in this drilling unit.

This is such a basic question, I know there are readers out there who know the answer.

For now, that's where we stand.

Original Post 

From the May, 2018, NDIC hearing dockets:
  • 26681 (case number, not permit number), Abraxas, Pershing-Bakken; 16 wells on an existing 1280-acre unit; McKenzie; section 17/20-150-96;
The map as it stands today. Only section 20-150-96 is shown; section 17 is not show, but all horizontals run north into section 17, and there are no other wells sited or running through section 17. There is an old vertical well in section 17 (#8816) that is now permanently abandoned. I do not know whether Abraxas will put the wells in section 17 (which would be interesting) or in section 20. There are already nine (9) wells in this drilling unit, if one includes the ULW, and now Abraxas wants to add another 16 wells (1280/24 = 50-acre spacing). The map:

Deciphering Designations Of Twelve (12) New BR Permits; House Of Cards -- September 16, 2014

There may be errors on this page. Early on a lot of locations -- fields -- were inaccurate. They were updated from the NDIC website January 4, 2015. If something seems wrong, it probably is. Go to source if questions or to confirm / check data.

Note: with regard to the wells on this page, see also this link. 

Updates

May 22, 2020: production updated; production data here; 

January 28, 2019: production data updated; see below;

August 5, 2017: 18047, Teton 21-3H, recently taken off-line; also, #29428 also taken off-line recently; re-fracking one or the other?

August 12, 2015: with regard to the Kings Canyon wells, we have some new information -- from an update elsewhere --
#29434, 1,080, BR, Kings Canyon 3-1-27MTFH; 36 stages, 4 million lbs; t7/15; cum 118K 2/21; off line as of 8/19; back on line 2/20; is an important well from standpoint of understanding "legal" names of BR Kings Canyon wells in Camel Butte. In the original post below, written a long time ago, I suggested that the "M" in MTF stood for "middle Three Forks," a new term for me. In the old days, it was simply the upper Three Forks that was targeted whenever we saw "TF" in the legal name. Shortly thereafter, operators starting talking about the four benches in the Three Forks, and the "upper TF" became TF1, the first bench. Now, we see "middle Three Forks. In the application, this is identified as Three Forks B2 (second bench). From the well file, for #29434, "the Middle Three Forks Formation [in this location] is a 20-foot-thick zone (~ 52' below the base of the Lower Bakken Shale)." Later in the report, the target zone lithology was said to have been taken 13 - 30' below the base of the Lower Bakken Shale. Another interesting note: this is a 2560-acre stand-up drilling unit; this well is sited in the northernmost section 339 feet from the north line, and then runs south, as a long lateral. Formation tops:
  • KOP: 10,400'
  • Carrington State: 10,766'
  • Scallion: 10,772'
  • Upper Bakken Shale: 10,789'
  • Middle Bakken: 10,819'
  • Lower Bakken Shale: 10.885'
  • Upper Three Forks: 10,936'
September 19, 2014: in today's daily activity report, seven more BR Teton / Kings Canyon wells to be drilled in Camel Butte:
a 4-well pad in the SWSE quadrant of section 10-150-96 (right next to the SESW pad in same section 10):
  • 29461, 2,926, BR, RemingTeton 8-8-10MBH ULW, Blue Buttes, t7/15; cum 313K 2/21;
  • 29462, 2,565, BR, Teton 8-8-10TFSH, Camel Butte, t7/5; cum 197K 2/21;
  • 29463, 2,645, BR, Teton 7-8-10MBH, Camel Butte, t7/15; cum 293K 2/21; back on line 2/20;
  • 29464, 2,525, BR, Teton 6-8-10MBH, Camel Butte, t7/15; cum 284K 2/21;
a 3-well pad in the NESE quadrant of section 34-151-96:
  • 29465, 2,565, BR, Teton 7-1-3TFSH, Camel Butte, t7/15; cum 205K 2/21;
  • 29466, 2,124, BR, Kings Canyon 8-7-8-34MBH, Camel Butte, t7/15; cum 258K 2/21;
  • 29467, 1,566, BR, Kings Canyon 6-8-34UTFH, Camel Butte, t8/15; cum 208K 2/21;
September 18, 2014: from a reader -- see first comment -- There is also a 4-well pad in section 10,  kitty corner, southwest to section 34. Despite the different names, they are all on the same pad, lot 1 section 4-150-96:
  • 29048, 2,112, BR, Teton 2-1-MTFH, Camel Butte, t7/15; cum 162K 2/21; back on line 2/20;
  • 29049, 1,560, BR, Tetonnorman 1-1-3UTFH, ULW, Johnson Corner, t6/15; cum 272K 2/21;
  • 29050, 1,584, BR, Kings Canyon 2-8-34UTFH, Camel Butte, 4 sections, KOP - Dec 16; TD - Dec 21, 2015; 17 - 48 feet below the base of the lower Bakken shale; t7/15; cum 237K 2/21; back on line 2/20;
  • 29051, 2.064, BR, DeKing 1-8-34MBH-ULW, Camel Butte, t6/15; cum 341K 2/21;
Notice the combined names on permits #29049 and #29051 and the abbreviation ULW. These are overlapping spacing units and the ULW stands for Unit Line Well.

[In these long notes, I don't often take time to proofread them two or three times. There may be typographical and/or factual errors. I have no formal training and no background in the oil and gas industry. No one should make any financial decisions, or otherwise, based on anything they read here or think they read here. With regard to the Bakken I make every effort to be as accurate as possible, but I blog quickly and don't double- or triple-check most things. (With all non-Bakken items, expect satire, parody, humor, sarcasm, opinions, factual errors, etc.) With regard to the posted information, I could use Microsoft Word to do the same thing but it would be more cumbersome; HTML works much better.

Go to sources.]

Refer to the graphic below.

In today's daily activity report, BR was issued twelve (12) permits in Camel Butte oil field. Four wells will be placed on each of three pads. I noted the designations (which may have been used earlier, but if so, I've missed them, or never paid any attention).

The three pads are designated by the "red rectangles" in the graphic above, in sections 10, 27, and 34. 

The following wells will be placed on each of the three pads, as noted:

SWSE 34-151-96

I am assuming the "M" does not stand for monitoring, but of course that's always a possibility.

The usual designation for a horizontal in the middle Bakken is: MBH (sometimes simply "H").

The usual designation for the Three Forks Sanish, also often referred to as the upper Three Forks, has been TFS. I suppose there might be horizontals in the TFS designated as TFSH.

I could be wrong, but I believe what we used to call the TFS, is now the upper Three Forks, and which is now generally referred to as the first bench, TF1.

The underlying benches are TF2, TF3, and TF4. To date, it is accepted that some areas in the Williston Basin are productive in TF2 and TF3, but to the best of my knowledge, TF4 is not yet recognized as a productive target.

But I haven't seen any operator use those designations (TF1, TF2, or TF3) in the names of their permits/wells.

This is, just as one example, how Oasis "sees" the formations in the Bakken Pool, which I believe is the same way that CLR "sees" the formations:

From the September, 2014, Oasis presentation.

So, back to the BR permits above.

We have UTFH, MBH, TFSH, and MTFH in the BR permits above.

Until I'm corrected, I am assuming:
  • UTFH: upper Three Forks, but because there is also TFSH, this is most likely TF2;
  • MTFH: the middle Three Forks, and for the same reason, this is most likely TF3;
  • TFSH: the traditional (legacy) upper Three Forks, or TF1; and,
  • MBH: middle Bakken, of course.
Section 27 has all "M" wells: middle Bakken and middle Three Forks (TF3).
Section 34, with the "question mark," has "UTFH" and "TFSH" designations.
Section 10, with "MB, TFS" has the traditional "MBH," as well as the "TFSH" designation.

I could be very wrong; maybe BR had earlier permits which could explain all this and I simply missed them.

KOG has its own system for designating the various formations but I haven't sorted them out, nor have I have sorted out designations used by other operators.


Trivia: #8873 is still flowing, no pump. The Devonian was first drilled in 1982; re-entered the Madison in 1988; total production approaching 400,000 bbls of oil. They also drilled the Silurian in 1982 but it was dry. (Note: factual errors and typographical errors are possible.)

Of course, as Blondie's Chris Stein once famously said, "It was never raveled in the first place."

And now more unraveling.

CNBC is reporting: "big" Minnesota insurer is leaving ObamaCare site.
The "Blue Ox" of Minnesota Obamacare is calling it quits.
PreferredOne, the insurer that sold nearly 60 percent of all private health plans on Minnesota's Obamacare exchange, on Tuesday said it would leave that marketplace.
PreferredOne's plans were the lowest-cost options on that exchange, known as MNSure.
PreferredOne cited the costs of doing business on MNSure as the reason for its surprising decision, saying that selling plans is "not administratively and financially sustainable going forward," according to KSTP.com, the website of that Minnesota TV News network. 
This will be the first of many across the nation. Slowly, but surely. 

Remember, by executive order, most of ObamaCare is on hold, delayed until 2015, and 2016.

House Of Cards - Fake

My wife and I have just finished watching Season 1 of "House of Cards," and are now starting on Season 2 having watched the first two episodes (of Season 2).

SPOILER ALERT.

I really, really enjoyed Season 1 but with the death of Zoe at the end of Season 1, I've pretty much lost interest in the series (I've lost interest, but I still watch it). The music is still worth listening to, although my television speakers don't do the bass justice.

I've also lost interest in the series because as "incredible" (as in "unbelievable") as it was coming to be with each new episode, it could not keep up with what seems to be occurring in real life.

Just How Effective Is Fracking (Radially)?

Early on, I suggested the "effectiveness" of fracking extends out no more than 500 feet radially. See this note posted back on October 11, 2011:
Somehow the conversation got around to "how many wells in a section?"

Of course that depends on how many formations one is talking about and how "good" the location is.

There is also the question of how effective fracturing is the farther one gets away from the borehole. I suggested that the general consensus is that fracturing is effective out to 500 feet laterally (500 foot radius, or 1,000 feet diametrically) suggesting 4 to 5 wells average across a 5,280-foot section line. Note: "general consensus" in previous sentence.

I suggested that it is very likely that fracturing is not necessarily effective that far out. I am way beyond my depth here, so it was just idle chatter. And then this: Coincidentally I see that "luckyone" elsewhere has opined the very same thing -- back on September 22, 2011. I don't recall reading that entry before (although I probably have) but the point is that there are at least a couple of us armchair observers suggesting that it may be as little as 300 feet laterally or radially. That is a game changer. I also think (and have previously posted) that the farther away from the well, the less effective the fracturing. And, of course, that is borne out by the number of reports in which not all stages were successfully fracked, and usually it is farther out than closer in.
Fast forward to May, 2013, and Oasis corporate presentation, slide #10. Oasis plans to:
  • vary spacing distances to as low as 400 feet in certain areas (equates to 6 wells per formation in single spacing unit). [The link will take you to the current corporate presentation which will change over time; this refers to the May, 2013, Oasis presentation only.]
If that pans out, and there are four payzones in the "better" Bakken (middle Bakken, TF1, TF2, TF3), that could be as many as 24 wells in one spacing unit. [By the way, CLR has a graphic that suggests one could see as many as 40 wells in one spacing unit.]

24 x 300,000 = 7.2 million bbls/spacing unit @$50/bbl = $360 million/spacing unit.

By the way, contrary to some folks' early concern, there are now indications that fracking a "new" well actually improves the production of an older, neighboring well. Of course, the jury is still out on that, but it certainly makes common sense.

September 11, 2013: from Mike Filloon --
The most important is the Wahpeton Pad. Continental chose the important location to drill a total of 32 wells from the middle Bakken to the 3rd bench. Since this was the first 160-acre pilot project, it very well could be the best area overall for pad drilling.

Meanwhile, the "Charlotte" wells sited in either section 22 or 27-152-99, Banks, but all probably drilling 22/15-152-99:
  • 19918, 496, Charlotte 1-22H, middle Bakken, SWSE 22-152-99; Banks, 30 stages; 2.5 million lbs; t6/11; cum 360K 4/20; total depth: 21,090 feet;
  • 23664, 657, Charlotte 3-22H, Banks, TF1, SESE 22-152N-99W, t11/12; cum 186K 4/20;
  • 21128, 692, Charlotte 2-22H, Banks, TF2, SWSW 22-152-99; 30 stages; 2.3 million lbs; t10/11; cum 255K 4/20; total depth: 21,358 feet;
  • 23612, 673, Charlotte 4-22H, TF3, 4 secs, Banks, [Update: see press release, December 3, 2012], t7/13; cum 173K 4/20;
  • 23608, 1,303, Charlotte 5-22H, Banks, ?TF4, 4 secs; t6/13; cum 248K 4/20;
  • 23664, 657, CLR, Charlotte 3-22H, Banks, t11/12; cum 186K 4/20;
So, unless I'm misreading the GIS map server and/or the permits, it appears the Wahpeton wells will be parallel to the Charlotte wells, in adjoining sections (spacing units). But the Wahpeton wells will be running north-to-south; and the Charlotte wells will be running south-to-north.

By the way, look at #23664, Charlotte 3-22H, still confidential, but production runs for first month:

What do you notice?  Yes, it was hooked up to a natural gas pipeline almost immediately. As the well density increases, the natural gas flaring will take care of itself. Already we are starting to see this happen on a larger scale. In the most recent Director's Cut:
Additions to gathering and processing capacity are helping with the percentage of gas flared dropping to 29%. The historical high was 36% in September 2011.
With more wells/month being drilled; more production/well; to see a downward trend this early in the boom speaks volumes about a non-issue.

***********************

And, then, of course, to the east, in the next spacing unit to the east are the very good Chicago/Syracuse wells.
