I know nothing about Mineral Rights . I know years ago I received letter about Pooling. drilling etc XTO Energy Common source of supply Goddard. Size of Unit. !640 acre When I receive a royalty I only see Jacob. In love Co I thought I used to see Logan, Goddard and different sections and townships The checks are almost not worth the paper. How do i know what the family owns I am sorry I feel way out of my league and would love some schooling . Was all the money. they put into the horizontal wells worth it Asking what’s it’s worth ,how to tell how many sections are owned what does it all mean ??! Thank you Penny Nichols
