Testing the Lower Benches of the Three Forks North Of Williston, Divide County, The Tangsrud Wells

Updates

February 8, 2013: I received this comment from a reader earlier. In case some folks don't read comments, I am re-posting part of it here:

I just talked our land man in ND and he told me that the 14 wells or "more" that is happening especially with CLR will become the norm. It seems that the Hamlet field along with others are all being talked about for multiple wells everywhere. The Milton wells have three, plus the Rosenquist will have three starting shortly. They may become 14 or more wells in the future. All the oil companies are talking about it. I think the Milton wells come off conf next week. And that might determine how many more.

February 8, 2013: Mike Filloon on EURs for the Three Benches; this is a "cut and paste" from an earlier post:

From Filloon on KOG, May 20, 2012:

Kodiak Bakken EURs in this area are 800 to 900 MBoe. Upper Three Forks EURs are 700 to 800 MBoe, plus there is possible upside to additional benches. Continental and Burlington Resources have both tested the second bench successfully in areas very close to the Koala Prospect. Whiting is also testing the second bench of the Three Forks. There are also two benches below, for a total of four Three Forks benches. Continental has stated the second has been consistent throughout its acreage, but the third and fourth benches have hot spots throughout the Williston Basin.

February 8, 2013: the Tangsrud wells have been re-arranged on this post based on formation that is being targeted, so that one can easily compare the Tangsrud wells with the Wahpeton wells.

February 7, 2013: on the daily activity report, four CLR Tangsrud wells, which will be added to those in the original posting. CLR now had 12 new permits for wells in section 1-160-96, Hayland oil field.

Original Post (updated with the new permits)

[Note: this is one of the very few "original posts" that is being updated to reflect significant changes.]
On May 13, 2013: there is a 6-well pad, two 2-well pads (both very close together, almost a 4-well pad), four single wells.

It looks like CLR is testing the lower benches of the Three Forks north of Williston in Divide County; four were added on the February 7, 2013 daily activity report:

• 17649, 922, CLR, Tangsrud 1-1H, t7/09; Dolphin, cum 123K 3/13; lateral runs south in Hayland, but NDIC says they are in Dolphin field (cannot be correct)
• 19107, 488, CLR, Tangsrud 2-1H, t11/10; Dolphin, cum 87K 3/13; lateral runs south in Hayland, but NDIC says they are in Dolphin field (cannot be correct)
• 24924, conf, Tangsrud 14-1H, Hayland, rig-on-site, May, 2013;
• 24965, conf, Tangsrud 5-1H, Hayland,
• 24967, conf, Tangsrud 9-1H, Hayland,
• 24928, conf, Tangsrud 11-1H1, Hayland, rig-on-site, May, 2013;
• 24936, conf, Tangsrud 8-1H1, Hayland,
• 24924, conf, Tangsrud 3-1H2, Hayland,
• 24930, conf, Tangsrud 13-1H2, Hayland,
• 24964, conf, Tangsrud 6-1H2, Hayland, 
• 24966, conf, Tangsrud 10-1H2, Hayland,
• 24929, conf, Tangsrud 12-1H3, Hayland,
• 24934, conf, Tangsrud 4-1H3, Hayland, rig-on-site, May, 2013;
• 24935, conf, Tangsrud 7-1H3, Hayland, rig-on-site, May, 2013;

I assume the "H" designation: middle Bakken; "H1" the TF1; the "H2" the TF2; and, the "H3" designation, the TF3. With the four additional wells added February 7, 2013, there are five wells with the "H" designation; there are two wells with the H1 designation; four wells with the H2 designation; and, three wells with the H3 designation.

So,

• 5 wells: middle Bakken
• 2 wells: TF1
• 4 wells: TF2
• 3 wells: TF3

Hayland oil field is a two-section oil field in the far southeast corner of Divide County. It looks like the field is about 20 miles due north of Tioga, the oil capital of North Dakota. There are already two long lateral Bakken wells in this oil field, and one older Madison well.

The other producing well in this field is an old Madison well that was re-entered in 2003 targeting the Bakken (as a vertical well), at which time the Madison was taken off-line. Only the Bakken in this well is currently producing, maybe a 100 bbls/month.
