Per mineral acre royality average

I have 40 plus acres in Williams County, North Dakota.

It is leased now to an oil company. And they will be drilling soon.

This is in the Bakken/Sanish 3-Forks. Prime stuff I hear.

What would the average royalty per acre be?

Well if you already have a signed lease it really has no bearing on your minerals. Unleased minerals will go anywhere from 18% to 20% depending on what area they are in.
