From the May, 2012, NDIC hearing dockets:
17789, Oasis, Sorkness-Bakken, 6 wells on 4 existing 1280-acre units; 24 wells; Mountrail County
17790, Oasis, Bonetrail-Bakken, 6 wells on 5 existing 1280-acre units; 30 wells; Williams County
17791, Oasis, Sanish-Bakken, 6 wells on an existing 640-acre unit; Mountrail County
17792, Oasis, Camp-Bakken, 6 wells on 3 existing 1280-acre units; 18 wells; McKenzie County
17793, Oasis, Willow Creek-Bakken; 6 wells on an existing 1280-acre unit, McKenzie/Wms
I did this quickly; didn't double-check for accuracy, and may be misreading the dockets. But this is my initial take.
I am not concerned with "absolute accuracy" -- whether I'm off by a few wells or not. It's the general picture I'm interested in. In this case, 6 wells on a 640-acre spacing unit; six wells on 1280-acre spacing units. Compare with 8 wells on 1280-acre spacing units that Zenergy is looking at.
