February 26, 2013: all but two sections are now held by production. All horizontals are long horizontals, except for two short laterals. There are no rigs in the field at this time.
February 26, 2013: Nick H over at Teegue's Bakken Shale Discussion Group has noted that EOG has a great Short Prairie well:

October 16, 2012: no rigs in this oil field this date
Original Post
The Round Prairie oil field is very, very active right now: four rigs on site in this small field, about 20 sections. It is "owned" by EOG. The field is directly west of Williston, North Dakota, and abuts the Montana border. In fact, the sections along the border are only about half the size of a "normal" section.There are currently four rigs on site:
- 19928, 651, EOG, Round Prairie 7-1201H, Round Prairie, Bakken, running north, t7/11; cum 106K 12/12;

We have minerals located in a section in Williams County next to Montana which is smaller than a regular section. I talked with the NDIC and was told this would be a 640 spacing unit.
ReplyDeleteIt looks like the spacing will vary in these smaller sections.
ReplyDeleteAccording to the NDIC GIS map server, the smaller sections along the Montana border will be "combined" with the abutting 640-acre sections in some fields (including Round Prairie) to give 960-acre spacing. That may not be true in other areas.
The following sections are shown as 960-acre spacing on the GIS map server.
Hebron field (note the orientation of the spacing units):
Sections 10-15
Sections 11-14
Sections 22-27
Sections 27-26
Sections 34-35
Rounded Prairie field (note the orientation of the spacing units):
Sections 2-3
Sections 10-11
Sections 14-15
Sections 22-23
Sections 26-27
Painted Woods
Sections 2-3
Interestingly, farther south, some of the "smaller" sections are not designated yet on the GIS map server as to spacing size.

ReplyDeleteThe "Strandahl" field is where our minerals are located (Section 31). I think G-3 Op. has this area temp. spaced. Is this a 640 or 960 acre spacing unit?
Yes, all those "half-sections" along the Montana border are 640-acre spacing by combining two sections into one for spacing.
ReplyDeleteSo, in the Strandahl field, the following sections are combined into one 640-acre spacing unit:
Sections 6-7
Sections 18-19
Sections 30-31
And that is true for other sections north and south of this field along the Montana border.
The Strandahl field is about eight miles north of the Hebron field on the far west (along the Montana border). The Strandahl field is 36 sections (of course, the six sections on the west are "half-sections") and has one producing well and one well on the confidential list.
Oh, I forgot, I should have added. This information can be found on the NDIC GIS map server.
ReplyDeleteWhen you get to the map, go to the legend on the sidebar to the right of the map, and expand the "Drilling and Spacing" file, and by checking the spacing under the "Bakken" one can find the spacing of most areas inside the Williston Oil Basin.
I think as far as Round Prairie wells go, you might be impressed with the
ReplyDelete4-805H I believe nearly 50k barrels in three months. Unless I read it wrong.
You are reading that correctly: 50,000 bbls in less than three months.
DeleteThere's something else that is noteworthy about that well, also. I will post it later, but I'm watching "Columbo" at the moment. Smile.
This is huge (at least for me). Thank you for taking time to comment.
