Looking for information on Grandparents property

I was recently given documentation by my mother in which was paperwork that showed she owned 160 acres in Renville County. There are two references to the property. They are:

township159 North, Range 85 west
section 21: NE 4
township 160 North, range 85 west
section 17: SE 4
Can anyone point me in the right direction or tell me where this property is located specifically and whether there has been any activity on it? There are a few oil lease documents in the paperwork but none active that I can see.
Thank you,

Hi Kevin, the townships that you give are not in Eden valley township not sure what township they are in do a search for them here: https://www.dmr.nd.gov/oilgas/findwellsvw.asp, I hope this helps you.
