n: an interest carved out of the lessees working interest. It entitles its owner to a fraction of production free of any production or operating expense, but not free of production or severance tax levied on production. An overriding royalty may be created by grant or by reservation. Commonly, an override is reserved by the assignor in a farmout agreement or other assignment. An overrides duration corresponds to that of the lease from which it was created.
