Original Post

This is one of my most-visited posts: fracking companies in North Dakota.

I posted that some months ago, at a time when I was pretty close to the Bakken geographically, and was pretty comfortable with the list based on comments I received.

The list may need updating; I don't know.

If there are errors in the list, please let readers know.
