Anyone offering to help you here is going to need a lot more information. Are the minerals leased? What County? How long producing? …etc… in fact there are too many etcs to be of any use… and this is all assuming you have to sell because if not, then that is a whole new game too… I know a guy who sold 5 acres to a family member for $10,000 an acre in a new Bakken well spacing… he only sold some of the acres in order to have money to participate in that well… anyway… if anyone is going to help you, be prepared to offer way more information.
