Denbury Completed Wells Update -- Bakken, North Dakota, USA

Denbury (DNR) provides the following information in its December corporate presentation.  DNR says these wells were completed in 2010. Some of these wells have been reported elsewhere on this blog. The IPs are based on "consecutive 24-hour tests." In some cases, the IP that DNR reports is significantly greater than that reported in the NDIC file report. On my blog, the IP report can vary, depending on the source, and I seldom provide the source. If there are two conflicting numbers, the larger number is probably a "24-hour flowback test" provided in a corporate presentation; the lower number is probably the number reported in the NDIC file report, which is more likely a 30-day, or even a 60-day average.

DNR reports that the Klamm well below was in the Cherry oil field; my database shows the Siverston oil field, east of Watford City; the Cherry Creek oil field is southwest of Watford City, but DNR calls this area their "Cherry" prospect.

They also refer to the non-Bakken formation as the "Sanish" formation. I assume that is the Three Forks formation. Early on, most folks referred to this formation as the Three Forks Sanish; then, the Three Forks/Sanish; and, now, most refer to it simply as the  Three Forks formation.

So, with all that preamble, here goes (well name, area, formation, 24-hour IP):

• Werre Trust 44-34H, Bear Creek, Sanish, 2,532 
• Porcupine 14-35H, Bear Creek, Sanish, 1,681
• Porcupine 11X-2H, Bear Creek, Bakken, 1,885
• Swenson 31-33SWH, Charlson, Bakken, 2,355
• Gilbertson 11-26H, Charlson, Bakken, 1,500
• Beckert 24-7H, Bear Creek, Bakken, 1,519
• Klamm 34-9NWH, Cherry, Bakken, 1,212
• Hanson 11-12H, Murphy Creek, Bakken, 944
• Jorgenson 34-9, Bear Creek, Sanish, 1,471
• Joseph 11-1H, Camp/Indian Hill, Bakken, 1,329

The 60-day average dropped to the 400 - 800 range in most cases.

A reminder: DNR acquired Encore back in 2009 and these wells were permits filed by Encore.

SeekingAlpha: Another "Bleak" Assessment for Natural Gas -- Not a Bakken Story

Link here.

The bottom line from that article:

Price is low and spreads are tight – so the prospect for a 25% haircut from here to $3.30 is remote. But the prospects for price gains in gas from here through the next two months are bleak to quite bleak and the chance for gas to lose 10% over the next couple of weeks looks real.

A Nice Sagebrush Madison Well in Bottineau County; Five Wells On One Pad -- North Dakota, USA

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.
