Introduction
If you are familiar with mineral rights, you are probably aware of the term Net Mineral Acres, or NMA. You may have also heard the term “NRA,” which stands for Net Royalty Acres. But what is the difference between these two measurements? How do you calculate one from the other? Read on to find out.
Definitions
Net mineral acres and net royalty acres are two distinct concepts in oil and gas property ownership that represent different types of interests and economic rights in mineral resources.
Net Mineral Acre Definition
Net mineral acres refer to the actual fractional ownership interest in the mineral rights beneath a tract of land. This represents the owner’s proportional share of the minerals that can be extracted from the property. For example, if you own an undivided 1/4 mineral interest in a 100-acre tract, you would have 25 net mineral acres. The mineral interest owner typically has the right to lease their minerals to an oil and gas company and receives lease bonus payments, delay rentals, and royalty payments based on their fractional ownership. Mineral rights can be severed from surface rights and sold or transferred independently.
IN SUMMARY: The number of NMA you own determines your total percentage of ownership out of a tract’s gross acres. In other words, it refers to the number of mineral acres in a given tract that you own.
Net Royalty Acre Definition
Net royalty acres, on the other hand, represent the economic interest in production royalties without necessarily owning the underlying mineral rights. This is calculated by multiplying the gross acres by the royalty percentage. For instance, if you have a 1/8 royalty interest (12.5%) in a 100-acre lease, you would own 12.5 net royalty acres. Royalty interests can be created through various means, including non-participating royalty interests, overriding royalty interest, or carved-out royalty interests that have been separated from the mineral estate.
IN SUMMARY: NRA is a different method of expressing mineral rights ownership that takes into account the fact that a specific mineral acre may have multiple owners with different levels of interest. It is calculated based on the royalty percentage that the minerals have been leased at.
Examples:
Converting between net mineral acres (NMA) and net royalty acres (NRA) requires understanding the relationship between mineral ownership and royalty rates. These conversions are essential for evaluating comparable interests and determining fair market values in transactions.
Converting NMA to NRA
Let’s say you own 64 NMA in a tract of land that have been leased at a 15% royalty rate. You can use the following formula to calculate the number of NRA that you own:
If you plug in the values above, you would get:
RESULT: Your 64 Net Mineral Acres generate the same economic benefit as 76.8 Net Royalty Acres when leased at a 15% royalty rate.
Converting NRA to NMA
Let’s say you own 83 NRA in a tract of land that have been leased at a 22% royalty rate. You can use the following formula to calculate the number of NMA that you own:
If you plug in the values above, you would get:
RESULT: Your 83 Net Royalty Acres generate the same economic benefit as 47.2 Net Mineral Acres when leased at a 22% royalty rate.
