Land ownership

How do I find out if I own the land. I have received a very lucrative offer from ferrell oil company for the property located at township 8 south, range 2 east, I.M. sections 12 and 13 love county Oklahoma. I have no connection to this land and I dont even know how they got my name and address. Could this be a scam?
