Seven Wells on One Section (640-Acre Spacing Unit) -- Slawson, Denbury Onshore -- Bakken, North Dakota, USA

If I am reading the NDIC September dockets correctly, both Slawson and Denbury Onshore are proposing to put 7 density wells in one section. I went through the dockets fairly quickly, so I may misunderstand what I'm reading, but someone will correct me if I'm wrong.

Here are the case numbers from the September, 2011, NDIC dockets that suggest to me, 7 wells on 640-acre spacing units. The dockets can be found at the NDIC website, linked at the sidebar on the right, under "Data."
