So, Which County Is Averaging Better IPs? McKenzie County or Mountrail County? -- Bakken, North Dakota, USA

I will leave this up for just a few days and then remove it. It is simply raw data, very unscientific, but "anonymous" suggested that in the past few months, McKenzie County was reporting better IPs than Mountrail County.

So, let's see. 

In 2010, McKenzie County was granted 330 permits, compared to 426 permits for Mountrail County.
Of the wells that have reported IPs, the data is as follows. McKenzie is  the left hand column; Mountrail is the right column.

The average IP in McKenzie County (left hand column) is 1,274 bbls.
The average IP in Mountrail County (right hand column) is 1,141 bbls.

The IPs are generally taken from the official NDIC daily activity reports, but on many occasions I used data from corporate presentations. I was not always careful about bopd vs boepd, so the entire exercise is suspect. However, the law of large numbers would suggest that I made as many errors in each column (on a percentage basis) and thus the analysis is probably not too far off.

So, there you have it: a fairly meaningless exercise, but someone asked the question, and this is the data I have (as imprecise as it might be). 

McKenzie County                            Mountrail County
