Random Note On A Madison Sweet Spot In The Williston Basin

I always get a kick out of finding sweet spots in the Williston Basin. These are Madison wells in Lone Butte oil field, right on the county line between McKenzie County and Dunn County, about 20 miles southeast of Watford City. Look at how long some of these wells have been active, and look at some of these production numbers.

Interestingly, there is almost no Bakken activity in this area yet.
