November 28, 2010: Status of EOG wells in 151-91, Van Hook field updated; see below.
April 1, 2010: Another "Liberty" well; #18877, Liberty 103-13H, NWNW 13-151N-91W. Liberty is the name of the township.
ORIGINAL POST
It's a quiet news day (for the moment), so I will join the discussion guessing what EOG plans to do with two permits granted yesterday.
The two permits under discussion are in the Van Hook oil field, in a section adjoining the prolific Parshall oil field. The two wells will be on the same pad, 100 feet apart from each other in the northwest quadrant of the northwest quadrant of section 36:
18827, Liberty 10-36H, 36-151N-91W, short lateralThese two wells will be on the same pad, and will be in the section closest to the river to allow drilling under the river.
18828, Liberty LR 16-36H, 36-151-91W, long lateral
April 30, 2010: new permit with "LR" designation -- #18979, EOG, Liberty LR 14-23H; section 23 close enough to river to drill horizontal under it
My opinion: the short lateral will go southwest and remain in section 36. The long lateral will go directly west and drill into sections 34 and 35.
The simple nomenclature for 18827 (10-36H) is shorthand for a "development" well.
I have not seen "LR" before and not sure what it means. Since most, if not all, of the EOG wells in the Parshall to date have been short laterals, I think the "L" in "LR" refers to long lateral. Does the "R" mean under the river? If so, why would that matter? Because #18828 is simple nomenclature (no 100, no 101, etc.) suggests to me this is also considered a development well in the Middle Bakken.
Township T151N-91R is Liberty Township.
Township T152N-91R is Van Hook Township.
Because of the river, there are only twelve (12) sections on which a pad could be placed: 1, 2, 11, 12, 13, 14, 23, 24, 25, 26, 35, and 36. In addition, six (6) additional sections under the river could be reached with long laterals, and it appears section 34 will be the first such section under the river to be reached.
With the two permits under discussion (above), EOG will not be putting a pad on section 35. That leaves eleven (11) pads.
Looking at the GIS map server (and including the two newest permits), EOG has at least one permit in each Section of 151-91 that is not under the river. All are short laterals unless otherwise stated: (current status in red, updated Nov 28, 2010)

Section 36: 19919, Liberty LR 21-36H
Opinion: look for permits in sections 14 and 23 to be long laterals, with names: Liberty LR XX-14H and Liberty LR XX-23H, unless the acreage belongs to someone other than EOG (e.g., Slawson).
Now switching gears (this has nothing to do with drilling under the river in the Van Hook/Parshall fields):
Look at the December 17, 2009, docket, specifically case 11939, a request for 99 more wells. EOG requested that the Van Hook or the Parshall pool be extended by a total of 33 more sections. In 151-91, EOG wanted to add sections 9, 16, 21 - 28, 34 - 36, a total of 13 more sections, which are all under the river. In addition, EOG wanted to drill up to three (3) wells in each of these sections with 640-acre unit spacing. Again, I have opined that the "three" refers to three formations: the Middle Bakken, the Upper TFS, and the Lower TFS; more likely, now, two into the middle Bakken and one into the TFS.
Case No. 11939, Dec 17, 2009: Application of EOG Resources, Inc. for an order extending the field boundaries for the Parshall or Van Hook-Bakken Pool to include the following lands: Sections 12, 13, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35 and 36, T.151N., R.90W.; Sections 9, 16, 21, 22, 23, 24, 25, 26, 27, 28, 34, 35 and 36, T.151N., R.91W., Mountrail County, ND; further amending the field rules to allow the drilling of up to three horizontal wells for each 640-acre spacing unit on the following lands: Sections 1 through 36, T.151N., R.90W.; Sections 1 through 36, T.152N., R.90W.; Sections 1, 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 19 through 36, T.153N., R.90W., Sections 1 through 36, T.154N., R.90W.; Sections 25, 26, 27, 28, 31, 32, 33, 34, 35, and 36, T.155N., R.90W.; Sections 1, 10, 11, 12, 13, 14, 15, 23, 24, 25, 26, and 36, T.151N., R.91W., Sections 1, 2, 11, 12, 13, 14, 15, 22, 23, 24, 25, 26, 35, and 36, T.152N., R.91W.; Sections 5, 6, 7, 8, 17, 18, 19, 20, 29, 30, 31, and 32, T.153N., R.89W., Mountrail County, ND, and further redefining the pool limits for the Parshall-Bakken Pool and such other relief as is appropriate.
How many well's can they put on your land..(640 acre)?
ReplyDeleteI'm not sure what you are asking, whether you mean how many wells could physically sit in one section (640 acres) or how many wells (vertical or horizontal) could produce oil from one section.
ReplyDeleteIn the old days, some vertical wells had spacing as low as 40 acres, I am told. With that spacing, one could put in as many as 16 wells in one section.
In the current boom, the spacing has generally been 640- or 1280-acre for Bakken pool wells. But it turns out that 640-acre spacing will support as many as three wells in some areas, maybe more.
In cases 11939 above, EOG was asking to put as many as three wells in some sections. There are other cases in which operators want to place even more wells in one section.
The number of wells on a section, and the spacing unit for royalty purposes are two separate issues.
