ORIGINAL POST (Permits and IPs Updated)

For those well acquainted with my craziness and irrational exuberance, you might get a kick out of this posting. In addition, it raises questions and I would love to hear from anyone who might have insight on what I'm seeing.

Bottom line: Slawson seems to be putting two wells on the same pad, with one lateral going north, and one lateral going south in the Big Bend / Van Hook oil fields. (Also, are they all "short laterals"?)

If you enjoy looking at the NDIC GIS map server and the NDIC active rigs page, this might interest you. This activity is all in the Big Bend and Van Hook oil fields, just south of New Town.

The wells with the following permit numbers are discussed below:

17504, Holst 1-33H, 1 sec, 825 boepd
17505, Wolf 1-4H, 1 sec, 309 boepd
17748, Fox 1-28H, 1 sec, 1,208, bopd -- Feb 9, 2010
17801, Jericho 1-5H, 1 sec, 750 boepd
17864, Jughead 1-26H (Thompson 1-35H), 1,255 bopd
18180, Stallion 1-1-12H, 2 sec, 2,735 boepd, 36 frac stages
18195, Cougar Federal 1-30H,1,264
18199, Zulu 1-21H, 290 bopd
18207, Machete 1-19H,1,215 bopd
18211, Minx 1-29H, 1 sec, 1,000 bopd, 34k in first 60 days
18220, Coyote 1-32H, 846, bodp, 40k in first 103 days
18239, Bazooka 1-20H, 876
18287, Skybolt 1-24H, 911
18331, Fed 1-34-35H-152-92, producing
18363, Howitzer 1-25H, 1,156
18364, Zephyr 1-36H, 1,637
18407, Ripper 1-22H, 2,369
18416, Wizard 1-35H, 849

NDIC reports that Slawson has only four active rigs, so the fact that sometimes I have more than four rigs on site in the list above (and below) I would assume is due to some rigs in process of moving from one site to another (and one well is a Questar well).

I noticed that Slawson was scheduled to start drilling Cougar Federal 1-30H in the Big Bend oil field, east of the river, inside the Fort Berthold Indian Reservation.  When I went to the map, I saw four rigs in the immediate area. Zooming in, this is what I found interesting:

Section 24-152-93: two wells (#18287 and #18363, Skybolt 1-24H (911) and Howitzer 1-25H (1,156), respectively, and both Slawson wells). These wells are right next to each other, maybe 100 feet apart. Based on their legal descriptions, it appears Skybolt will be a lateral in section 24 and Howitzer will be a lateral going south into section 25. Both wells are listed as confidential, but are reported as producing or plugged, which in the current boom, suggests both are producing.

Section 30-152-93: two wells (#18195 and #18207, Cougar Federal 1-30H (1,264) and Machete 1-19H (1,215), respectively, and both Slawson wells). Again, these wells are so close to each other, one has to zoom in to separate them; they, again, appear to be about 100 feet apart. Again, based on their legal descriptions, it appears that Federal will stay in section 30, and Machete will be a lateral north into section 19.  There is a rig currently on 18195 and this is the well that is to start drilling December 9, 2009. A rig is now on site for the Machete well (18027).

Section 29-152-93: again, two wells (#18211 and #18239, Minx 1-29H (1,000) and Bazooka 1-20H (876), respectively, both Slawson). Repeat the chorus. It looks like Minx stays in section 21 and Bazooka is a lateral into the north, section 20. Both wells are listed as confidential, but are reported as producing or plugged, which in the current boom, suggests both are producing.

Section 35-152-93: again, two wells (#17864 and #18416,  Jughead 1-26H/Thompson 1-35H (1,255) and Wizard 1-35H (849), both Slawson wells. The Thompson well was originally a Windsor well, but in July 2009, it was obtained by Slawson, and apparently renamed. I don't know if there is a relationship between Windsor and Slawson, but it wouldn't surprise me).  With the new name, it is likely that Wizard will stay in section 35, and Jughead will go north to section 26. Wizard is confidential (I assume it has been drilled) and Jughead has a rig on site -- January 14, 2010).

Section 1, 151-93: again, two wells (#18364 and 18180, Zephyr 1-36H (1,637) and Stallion 1-1-12H (2,735), both Slawson wells). The designation of 18364 suggests it will be a lateral into section 36 to the north, whereas the Stallion may be a "long lateral," extending in both sections 1 and 12 to the south.  Stallion is confidential with no news, and Zephyr has a rig on site.

Section 5, 151-92: again, two wells right next two each other (#17801 and #18220, Jericho 1-5H and Coyote 1-32H, both Slawson wells). Jericho had an initial production flow rate of 750 boepd, a nice well; Coyote, even better, 846.

Section 28, 152-92: again, two wells, practically on top of each other (#17748 and #18199, Fox 1-28H (1,208) and Zulu 1-21H (290), both Slawson wells). Both are confidential but based on nomenclature, it looks like Fox stays in section 28 and Zulu goes north to section 21.

Obviously there is very little information on how good these wells might be. I mentioned Jericho (#17801) above with a nice initial flow rate of 750 boepd. In addition, another Slawson well (#17504, Holst 1-33H) reported a nice initial flow rate of 825 boepd. Slawson's #17505, Wolf 1-4H, reported an initial flow rate of 309 boepd. This is not a particularly remarkable well, but it might have been a single-stage fracture back in January, 2009, time frame. In the past year, "we've" come a long way in increasing the initial flow rates through multiple-stage fracturing.

Meanwhile, #18407, Ripper 1-22H (2,369), another Slawson well, 22-152-92, had an IP of 2,369.

#18331, Fed 1-34-35H-152-92, a Questar well, 34-152-92, is now producing (2 sections).

Some of these wells were mentioned in a NOG press release, November 4, 2009.
