Update: this is from the first comment below (in the comment section).
#19236, 680, Petro Harvester/Sagebrush, Asheim 2, in the Renville oil field in Bottineau County, is in fact two (2) wells with one lateral each. Both laterals start at the same point and are about three (3) degrees apart; one extends about 2,400 feet and the other about 3,200 feet. The actual formation is the Wayne formation, part of the Madison Group. According to that link the Spearfish is the youngest oil-producing formation in North Dakota which unconformably overlies the Madison Group across much of eastern North Dakota. The Spearfish Formation is productive where oil has migrated into it from Madison Group strata.
This is another stratigraphic link I have found useful.
Original Posting
Yesterday (Friday, January 14, 2011) I posted
my usual update regarding new permits, and highlighted several very nice Newfield and EOG wells, all with IPs around
1,000 or significantly higher.
I purposely left one very good well off the list because its IP paled in comparison to these thousand-bbl IPs and I did not want to get newbies wondering if there was a problem with a well with an IP less than a
1,000.
So, now to make up for that oversight, another great well that was noted in yesterday's daily activity report was #19236,
680, Sagebrush, Asheim 2, in the Renville oil field in Bottineau County. This has to be one of the best wells in that field. Not only that, this is a) not a horizontal well (if I understand the designation correctly); and, b) not a Bakken well. It is a Madison well.
The obvious question is whether the IP as reported is a 24-hour flowback, or something else. If this is a 24-hour flowback, this is a huge well for a Madison.
For comparison, from my database here are the IPs of other Madison wells that reported in 2010:
- 18612, 25, WLL, BSMU 3602X, Big Stick, Billings County
- 18625, 368, WLL, BSMU 3604, Big Stick, Billings County
- 18738, 50, Jayhawk, Knudsen 1, Crosby, Divide County
- 18740, 30, Jayhawk, Jenks 1, Crosby, Divide County
- 18899, 1, Sagebrush, Busch 2-5, Portal, Burke County
- 18902, 2, Sagebrush, Busch 10-5, Portal, Burke County
- 18962, 55, Sagebrush, Lodoen 11-7H, Kuroki, Bottineau County
- 18986, 59, Sagebrush, Johnston 1-22, Columbus, Burke County
- 19027, 111, Sagebrush, Erickson Et Al 1B, Renville, Bottineau
- 19028, 98, Sagebrush, Erickson Et Al 3B, Renville, Bottineau
- 19062, 37, Sagebrush, Wright 12-12H, Kuroki, Bottineau
- 19139, 99, Sagebrush, Erickson Et Al 1A, Renville, Bottineau
- 19177, 95, Cornerstone, Rawn 4-26H, Wildcat, Burke
- 19194, 37, Sagebrush, Lodoen 11-8H, Kuroki, Bottineau
Others, plugged or producing:
- 18751, Cornerstone, Karpyak 4P-33H, Upper Des Lacs, Burke
By the way, look again at #19139, Erickson Et Al 1A. That is one of five wells that Sagebrush is putting on one pad, SWSE 30-162N-82W:
- 19140, Erickson Et Al 4B
- 19141, Erickosn Et Al 3A
- 19142, Erickson Et Al 4A
- 19143, Erickson Et Al 2B
By the way, I have to thank an "anonymous" reader for calling attention to the Sagebrush well in Bottineau County. Thank you.
