FDIC - Stranger in title

Newfield drilled a well in a section where I purchased an ORRI from the FDIC in 1990. The original ORRI property is still producing. In Newfield's title opinion, they state that the FDIC is a stranger in title since obviously there was no conveyance document to the FDIC from what was probably a failed bank. How can I prove my ownership of my ORRI?

PS Newfield never informed me of a title requirement until I contacted them when I noticed they had drilled a well over a year ago in a section where I own an ORRI.

The conveyance documents would be the court action wherein the FDIC seized the asset which was sold to you.

You can prove your ownership by running title to your ORRI and chain it to the failed bank. Then follow the chain forward by finding when the bank failed and then find the relevant action that allowed the FDIC to seize the assets. The local abstract office will occasionally have that information. I find that the Oklahoma Closed, Merged, Renamed & Relocated Banks Report can be a helpful source of information as it narrows the date range to search.

I would also check with the company operating the still producing well and see if they completed a Division Order Title Opinion.

Thanks!
