Inherited mineral rights in two places-- new to this, BPX wants to purchase one of them

my family and I inherited mineral rights in Caddo Parish Louisiana and Panola County Texas.

In Panola it is Lewis-Miles Bell -Roberson 4H, 5H, 3H and Miles Bell Roberson A 2HJDF and AL 1HJDF. Silver Hill Energy is managing those royalties, and I am always getting letters from companies wanting to purchase them.

In Caddo Parish it is Section 3 Township 17 Range 16, and I have around a 3 acre ownership there. PBX is drilling there, and just offered me $8500 an acre to buy my rights.

Any help is welcome– I have spent time here and there trying to figure out what I have and what it’s worth, and a BPX Landman just figured. out the title chain for the Caddo property.
