UPDATE: I Stand Corrected On This: Another Well Put Back On Confidential List -- And Another Good Whiting Well in Their Pronghorn Prospect -- The Bakken, North Dakota, USA

Update

I am wrong with these examples regarding wells being placed back on the confidential list. Teegue provides a good explanation. The Pronghorn State Federal 21-16TFH is on the confidential list. Again, the Bakken Shale Discussion Group is the authority on Bakken issues. I am only an amateur, trying to figure out the Bakken. I'm learning as I go along. Please go to the link: lots of great information regarding the Bakken.

Original Note

20839, CONF-->DRL-->CONF, Whiting, Pronghorn State Federal 21-16TFH, Park, s6/11;

I could be wrong, but my database is usually pretty accurate. This well was confidential at one time; one could access the drilling report. Then it went on DRL status. Tonight, while updating Whiting wells in the Pronghorn prospect, I noted that this well is back on confidential status.

This appears to be accurate. It is listed as confidential but yet one can access the 141-page file report which would normally not be there if this well had been on confidential list all the time. 

The reason for noting this can be found at this post.

If I am wrong regarding this well I apologize, but this is the way it seems to me.

On another note, it looks like Whiting might have another good well in their Pronghorn prospect:
