My father in law passed away and we are trying to sort out his mineral rights. It looks like he had 3 different parcels. I can found paperwork about Dolar Energy from about 10 years ago but haven’t been able to find a contact phone # for them. I am hoping someone can tell me how you find out who pays the royalties and if any one has a contact # for Dolar Energy. This is all very confusing to me so any help would be greatly appreciated.
