Comparing Legacy And Corinthian Wells Targeting The Spearfish In North Dakota: A Random Update -- October 22, 2014

A reader noted this less-than-spectacular well in the Spearfish, coming off the confidential list today. There are two names that make up most of the Spearfish activity in North Dakota right now: Legacy and Corinthian. My understanding is that Legacy bought Corinthian acreage earlier this year, but permits are still being issued for both Legacy and for Corinthian.

A reader noted this less-than-spectacular well that was reported today:

• 28112, 11, Legacy, Legacy Berge 13-31H, North Souris, a Spearfish well, t6/14; cum --

I was curious: are the IPs of the wells significantly different between Legacy and Corinthian, and are their significant differences in IPs in the various Spearfish fields? The IPs are listed below for wells whose permits were issued in the given year. I did not include wells with permits from 2104; too many of them would not yet be completed.

About all I can tell, is that the "Corinthian" wells have marginally better IPs than the "Legacy" wells; and the North Souris oil field is probably a bit better than Red Rock.

I only looked at a couple of well files; it looks like these wells are being completed with 24 - 26 stages, and 200,000 lbs of proppant, compared to 2 million lbs and more of proppant in Bakken wells.

Maybe other readers have a different perspective. 

In a long note like this, there will be typographical errors. If this information is important to you, go to the source.
