Advise in leasing our families mineral rights


Hello, I’m seeking advise in mineral rights leasing for my mother-in-law. She owns rights in section 11-10N-14W. 160 acres more or less. I believe the prior company that leased it went bankrupt and she recently received an offer from Bistro energy for $500/acre, 3 yr term with a 2 yr option, and 3/16th royalty. I’m not sure if this area is productive or not. I’m not sure how I would find that out for her. My goal is to maximize her income from these rights. She just recently lost her husband and has asked me to assist her with this. This is un-treaded water for me so I’m reaching out to anyone with advice on leasing her rights. Thank you
