Assignment of Oil and Gas Leases of all Interest, Reserving An Overriding Royalty Interest

An overriding royalty interest is the right to receive revenue from the production of oil and gas from a well. The overriding royalty is carved out of the lessee's (operator's) working interest and entitles its owner to a fraction of production.

Oil and gas lease is an agreement between a mineral owner (lessor) and a company (lessee) in which the owner grants the company the right to explore, drill and produce oil, gas, and other minerals below the surface of the earth.

Calculating net revenue interest formula To determine net revenue interest, multiply the royalty interest by the owner's shared interest. For example, if you have a 5/16 royalty, your net royalty interest would be 25% multiplied by 5/16, which equals 7.8125% calculated to four decimal places.

Royalty Interest an ownership in production that bears no cost in production. Royalty interest owners receive their share of production revenue before the working interest owners. Working Interest an ownership in a well that bears 100% of the cost of production.

The value of an overriding royalty interest is simple to calculate since it is a percent of the working interest lease. The ORRI value is based on production on the acreage leased by the working interest.

Wellbore. An assignment can be limited to the wellbore of a well. A wellbore limitation means that the assignor is assigning only those rights to production from the wellbore of a certain well, arguably at the total depth it existed at the time of the assignment.

An overriding royalty interest generally entitles the owner of the interest to a specified share of the oil and gas produced under the terms of the lease. In Texas and in many other oil-producing states, overriding royalty interests are generally treated as interests in real estate.

Overriding Royalty Interest (ORRI) a percentage share of production, or the value derived from production, which is free of all costs of drilling and producing, and is created by the lessee or working interest owner and paid by the lessee or working interest owner.

An Assignment of an Oil, Gas and Mineral Lease is a document in which the original Lessee, and or their successors, assign either all or part of their working interest and/or net revenue interest that they own in that lease. This is leasehold interest. You can also assign or reserve interest in wellbores.
