I am an heir to mineral rights in the JS Nobles Survey A-526. The lease on these rights expired in Jan. 2011 but the address had not been changed on the lease during the leasing time. I have looked to see if any wells were permitted on that survey but am having trouble determining if any activity occurred at all. If anyone has any information on that area, I would appreciate the help. Thanks as I am trying to clear up some of my Dad's holdings.
