Resources to learn about what my mom inherited in Burke County, ND

I am helping my mom learn more about some mineral rights she inherited in Burke County, ND. From the lease, I can see there is about 1400 acres in one township, but not contiguous. She would own it with her siblings and some cousins.

I work actively in agricultural banking and very familiar with land records and happy to do my own research prior to hiring someone.

There was an exploration lease signed in 2014 and it appears one well may be producing (we have had companies inquire about purchasing the right), but no one is receiving a royalty check.

The land is in the following sections.

It appears to be an okay area, but not actively doing a lot of drilling and exploration at the moment.

Thank you in advance to any guidance provided.
