Storhaug Well -- Wildcat -- Near Dublin Oil Field -- Madison Wells? -- Bakken, North Dakota, USA

Update

November 15, 2013: there are a lot of comments to scroll through, and comments are not searchable by search engines, as far as I know. On this date, a reader posted this important note for those trying to follow the development of the Bakken. We had raised a question about some new wells in this area without the "H" designation; apparently they are horizontal wells, regardless. See comments posted about this date.  We also raised a question about 1280-acre vs 2560-acre spacing for new wells, which had to do with a 2560-acre spacing that included sections 1, 2, 11, and 12 in T157-R100. This was the answer provided by the reader:

I visited with HRC about this and the only wells affected will be any new wells along the section line between the two 1280 spacings (maximum 3 wells). All other new wells drilled will remain part of the original 1280 spacing. They sent me their drilling plan which is to drill up to 13 wells per 1280 spacing and 3 wells in the 2560 spacing.

November 22, 2011: New wells in the immediate area.

• 21882, PNC, Petro-Hunt, Dullum Family Trust 157-100-2C-1-1, wildcat

Three wells in a cluster, in the northeast corner of the next section to the west, 3-157-100:

• 21746, 653, Oasis/Zenergy, Mary 3-10H, wildcat, t1/12; cum 157K 4/20;
• 21747, 685, Oasis/Zenergy, Hanson 34-27H, Dublin; t12/12; cm 182K 4/20;
• 21748, PNC, Oasis/Zenergy, Mad Dublin 1-3H, Dublin/wildcat; a Madison well;

One well in the northeast corner of the next section to the west, 4-157-100:

• 20953, 343, Bruin/HRC/Petro-Hunt, Johnson Family Trust 157-100-4A9-1H, Marmon; s9/11; t2/12; cum 114K 4/20;

And finally, one more well, this one immediately across the section line from 20953:

• 21496, 791, Oasis/Zenergy, Hanson 33-28H, Church/wildcat, t5/13; cum 189K4/20;

I promised a reader I would do a stand-alone post on the Storhaug well:

• 19646, 482, Petro-Hunt, Storhaug 157-100-2A-11-1H, Bakken; s3/11; t8/11; cum 198K 10/16; 23 stages, sand only, no acid.

The well is a good well, but not yet great.

In looking up this well, I noted a peculiar well pattern in this section (2-157-100), which I have blogged about before, and perhaps in a big more depth:

• 19646 is in the northeast quadrant
• 21036 (PNC) is in the northwest quadrant
• 21161 is closer to the midline on the east; rather than near a section line where one normally finds horizontal Bakken wells.

In addition, a similar well, #21326 is also in an unusual location in the neighboring section.

• 21036, PNC, Petro-Hunt, Storhaug 157-100-2B-2-1 (note, it lacks "H" designation) Dublin field
• 21161, TA, Petro-Hunt, Ostad 157-100-2D-1-1 (also, lacks "H" designation) Dublin field
• 21326, PNC, Petro-Hunt, Swenson 157-100-1C-2-1 (lacks "H" designation), Dublin field

It's also interesting that the three latest wells are now in the Dublin field; the 19646 Storhaug well was a wildcat; the Dublin field must have been extended; if so, the GIS map server has not been updated to show that.

Now for the interesting part (and this is why I love to blog; one never knows what one might find):

Notice the three wells above that don't have the "H" designation. Could they be vertical wells? Could they be targeting the Madison forrmation. In the adjoining/same section (section 1-T157N-R100W):

• 11490, 31, Rim Operating/SM Energy (originally HNG Oil), Curran 1 1, Dublin, a Madison well; 1985; t1985; 383K 10/16; still producing a respectable 700 bbls/month (700 x $50 = $35,000/month with almost no expenses). This well has been a steady producer from the beginning. It has been producing steadily for 29 years; the longest it has been off-line in any one month was 8 days back in 1998.
