Random Examples of Non-Bakken Monster Wells In The Williston Basin

There are probably more examples, but for no particular reason here are four examples of some very old wells that have targeted three formations. All three formations are now PNA in one well; one formation is still producing in two of the wells; and in one well, two formations are still producing. The oldest well was spud in 1953. There could be typos; I was pretty tired by the time I got to these wells.
