Northeast Energy and Marion Energy Leasing

So I have family with around 40 ac in Marion County Pawpaw District. Current offer from Marion Energy is $2000. Per ac bonus at 15% net royalty. No surface rights. Leased about 8 years ago with another company for $4000. At 16% gross royalty. I know inflation has affected everyone so why do you think the offer is so low? They definitely plan to drill ,proposed pad site has been approved less than a mile away. Based on research of leases near ,the property will be at the end of the drill line. Any input or advice?
