My family has 40 acres about by Watonga. 11 acres of clear land and the rest is wooded. I believe we only own the surface rights to it. We got a letter today that they want to do a seismic survey on it. They offered us 750 dollars for the access. First question is do we have to let them do it at some point if the mineral rights owner agrees ? how much damage can we expect from it ? thanks ahead of time for your time.
