Is there a database of mineral rights

I received a court notice last week that my property in Oklahoma County is one that a company is planning on doing horizontal drilling under? It says I can appear in Tulsa County Court to say whatever I might want to. Then, this week I received a call from a Chance with Spring Rock Minerals saying he wanted to talk to me about some mineral rights in OK County. I can only assume he means the ones under my property, but I don’t even know that I own ANY mineral rights. Can anyone tell me if there is a database I can look it up on?
