Far Southwest Corner of North Dakota -- Multiple Red River Zones

This first well below was reported in the May 14, 2012, daily activity report, which led me to look at a few other Red River wells in the area:

• 10327, conf-re-entry, Encore, Olsen 1-30, Horse Creek, Bowman (note: no "H" designation). This well first started producing in January, 1984, and targeted the Red River (see Cedar Hills for an example of Red River wells); it produced a total of 212K bbls of oil; it last produced oil in 1996; Horse Creek oil field is in the far southwest corner of North Dakota, just a few miles southeast of Cedar Hills. Encore has another re-entry well in the same area:
• 8774, conf-re-entry, Encore, Mud Buttes Federal 2-12, Horse Creek (note, no "H" designation).
