To clear up some confusion, let’s first discuss the difference between a royalty interest and an overriding royalty interest.


Royalty Interest

When a mineral owner executes an oil and gas lease, the mineral owner (lessor) retains an oil and gas royalty, which is usually described in the lease as a fraction, such as 1/8th. A royalty is a portion of the proceeds from the sale of production. So if a well is successfully drilled by the operator (lessee), the mineral owner will receive an oil and gas royalty payment every month for as long as there is production on the leased lands or being allocated to the leased lands.

Overriding Royalty Interest

An overriding royalty interest (ORRI) is similar to a royalty interest in that it is also a portion of the proceeds from the sale of production. However, it is not retained under the terms of the oil and gas lease. An ORRI is granted, assigned and created under the terms of a separate document. The most common documents used to create of ORRI are:

  • Assignment of an Overriding Royalty Interest

  • Assignment of Oil and Gas Lease, where the Assignor retains an ORRI


A couple of different scenarios:


Oil Company takes an oil and gas lease from Mrs. Smith, the mineral owner. In the lease, Mrs. Smith retained a 12.5% mineral royalty.  Now, Oil Company owns the rights to 87.5% of the revenue, as 12.5% was retained by Mrs. Smith. As compensation for identifying the drilling locations, Oil Company assigns a 2%  ORRI (in the lease from Mrs. Smith) to Mr. Geologist. When a well is successfully drilled on the lease, the revenue from the sale of production will be split:

Mrs. Smith- 12.5% Mr. Geologist- 2% Oil Company-85.5%


Mr. Landman is speculating that Oil Company will be interested in leasing minerals owned by Mrs. Smith.

Mr. Landman contacts her first and leases Mrs. Smith’s minerals. The lease provides for a 12.5% royalty. Oil Company wants to drill on Mrs. Smith’s minerals but now has to negotiate a deal with Mr. Landman. Mr. Landman agrees to assign the lease to Oil Company and reserves a 5% ORRI. When a well is successfully drilled on the lease, the revenue from the sale of production will be split:

Mrs. Smith- 12.5% Mr. Landman- 5% Oil Company- 82.5%

An overriding royalty interest:

  1. Is carved out of the working interest (oil company) share of production

  2. Is not ownership in the minerals, but in the proceeds from the sale of oil and gas

  3. Is free from the drilling and completion costs

  4. Is “tied” to the oil and gas lease.  When the lease expires, so will the ORRI Buying and Selling ORRIs is a big business.
