Locating ownership etc for Property in Logan County

I live in CA from OKC. How can I find previous ownership/sell information and current property owner info for property in Logan County. My dad passed and we have no records available to us regarding his sell of this property and want to research mineral rights. I believe the records were destroyed in OKC flood of his home. Where do I start? All I have is my dad's name (leased with right to royalties/sold In 1980's and that it was located in Logan County.

Go to okcountyrecords.com and you can search by name.

Thank you I will start there.
