For the English land law concept of overriding interest, please see Overriding Interest.
An Overriding Royalty Interest (ORRI) is an oil and gas interest is separated from the participatory interest of what is called the working interest. It is percentage of gross production that is not charged with any expenses of from an oil and/or gas well. An ORRI is a covenant running with the land between the assignor and assignee. However, it expires if the associated leases expire.[1]
Calculating ORRI edit
The overriding royalty interest, for well units, is calculated as follows:
(Overriding Royalty Rate) × (Working Interest) × (Mineral Interest) × (Tract Participation Factor) = ORRI[2]
Where the terms are defined as follows:
- The working interest is the ownership interest that would require the participation in production expenses.[3]
- The mineral interest is the percentage of real property interest after severance of oil and gas from surface rights.[4]
- The Tract Participation Factor is: Number of Lease Acres of the Lessor divided by total number of acres.[5]
