Update On A Wildcat Well Northwest Of Mohall, North Dakota -- August 2, 2015

Over at the discussion group, a reader asked this question: Do you have any information on an oil well drilled in the Mohall area some time ago that turned out to be a Bakken and not a Madison?

I assume the well in question was posted at this link, February 20, 2015:
This well came off the confidential list today; it was a wildcat. Based on its location, I thought the Madison would have been the target; in fact, the target was the middle Bakken, and fairly shallow, which makes sense based on its location --
  • 28571, drl, Roff Operating Company, Osterberg 2-16 H1, wildcat, far north, and east, about 6 miles northwest of Mohall, near Little Deep Creek oil field, a Madison formation area; if a good well, might extend Little Deep Creek east, , no production data; very, very interesting -- the geologist's report states that the target was the middle Bakken; that the wellbore entered the middle Bakken target at 6,350 feet (shallow); oil present; gas values ranged between 50 and 100; the dipping suggests that anticlinal oil trapping structures could exist and be exploited; awaiting fracture/completion; spud August 20; ceased drilling September 13; total drilling days, 26; short lateral (640 acres);
This well came off the confidential list on February 20, 2015, and went to SI/NC status (it was drilled to total depth, but it was shut in before it was completed, and has been added to the "fracklog" or backlog of wells waiting to be fracked). This is the scout ticket (note that the pool is indeed the Bakken):
