Net revenue interest (NRI) is the percentage of production revenue an owner actually receives from a well after royalties and other burdens are deducted from the gross.
NRI answers a practical question: of every dollar of revenue from this well, what share is yours? It is expressed as a fraction or decimal (for example, 0.12500000 on a division order), not as acres. Two owners can hold the same number of net mineral acres in the same tract and still have very different NRI figures if their royalty rates, burdens, or unit shares differ. Surface ownership is not an input at all — a severed mineral owner holds no surface and still has an NRI.
Operators, purchasers, and buyers use NRI (or the equivalent decimal interest) to connect title to payment. If the decimal on your paperwork does not match what you believe you own, that gap is worth resolving before you rely on the number for planning or a sale.
A working interest owner pays a share of drilling and operating costs and owns a gross share of production — but their net revenue is smaller, because royalties and overriding royalties are carved out first. NRI is what is left after those burdens. Lease vocabulary for the broader grant sits in the oil and gas lease terms guide.
A simple way to think about it: gross working interest is the size of the pie slice before royalty burdens; NRI is the slice after those burdens come off the top. Cost-bearing owners care about both figures; royalty owners — and mineral owners whose tracts are under lease — usually track the cost-free decimal that drives their check. Cost-free status comes from the royalty reserved under a lease, not from mineral ownership itself: an unleased mineral owner who participates in a well, is pooled by order, or is developed under cotenancy rules can bear or reimburse costs out of production.
For a pure royalty or mineral owner, the figure that functions as your net revenue share is usually the decimal interest on your division order. People still say "NRI" in conversation, but division-order and revenue-deck language for non-operated royalty is often just "decimal interest."
Net mineral acres (NMA) measure ownership size in the minerals, not the revenue share from a particular well or unit. You can hold many net mineral acres and still have a small decimal on one well if the unit is large, your royalty rate is modest, or only part of your minerals sit in that unit. NRI/decimal answers "what share of this well's revenue is mine?"; NMA answers "how much mineral ownership do I hold?"
Typical burdens that sit ahead of a working-interest owner's net revenue include landowner royalties under the lease and any overriding royalty interests (ORRI) carved from the working interest. Non-participating royalty interests (NPRI) and other reserved royalties can also affect how production revenue is shared, depending on the chain of title.
Who bears a burden matters as much as its size. A lease royalty is normally shared proportionally by every working-interest owner. An override carved solely out of one owner's working interest is borne by that owner alone, so it reduces that owner's net revenue and nobody else's. Read the assignment or the override's own instrument to see which of the two a given burden is before you fold it into a calculation.
The exact stack is property-specific. A short illustration used across the industry: if a working interest is 100% of the working interest in a lease burdened by a 1/5 royalty and no other overrides, the working-interest NRI before further splits is often described as 80% of production revenue (1 − 0.20). Real wells add unit participation factors, multiple tracts, and additional burdens — so treat any illustration as orientation, not a substitute for your division order.
Most owners first meet the number on a division order or a recent royalty statement / check stub. The division order states the decimal interest the payor will use; the stub shows how that decimal was applied to a production month. Title instruments (mineral deed, probate decree, assignment) explain why you own an interest, but they may not restate the well-level decimal.
If you have limited paperwork, start with the state, county, operator or payor name, well or lease name, and anything you know about the interest type.
Anyone reviewing an interest — including a direct buyer — needs a credible revenue share to understand past checks and to think about future cash flow. NRI (or decimal interest) sits alongside producing status, well performance and decline, operator activity, lease terms, title complexity, and commodity conditions. Those are factors, not a public price list: this page does not publish dollar offers, acreage price bands, or income multiples.

When paperwork is incomplete, clarifying the decimal early reduces back-and-forth later in title review. Inherited interests, trusts, and multi-owner tracts often need extra time because several decimals and instruments may have to line up before a deed can close.

For a working interest owner, NRI is the working interest share less the burdens attributable to that interest, adjusted for any unit or tract participation factor. The familiar shorthand — working interest multiplied by (1 minus the total burden) — holds only where every burden is shared proportionally across the working interest, as a lease royalty normally is. An override carved solely out of one owner's working interest and stated as a gross decimal comes off that owner's share alone, and the shorthand overstates the result. The controlling figure for payment is the decimal interest on your division order — not a back-of-the-envelope estimate.
For a royalty or mineral owner, your division-order decimal interest functions as your net revenue share. The label "NRI" is used most often for working interest ownership, but owners and buyers often use the terms interchangeably when talking about "what share of the check is mine."
Because royalties, overriding royalties, and unit participation can reduce a gross ownership share down to a smaller net revenue share. Acreage alone does not equal the decimal applied to a specific well.
Look for a decimal interest on your division order and on recent royalty statements or check stubs. Deeds and probate papers explain ownership but may not restate the well-level decimal the payor uses.
Not by itself. A higher net revenue share matters, but value also depends on production, decline, remaining well life, operator activity, location, lease terms, title condition, and commodity prices. Compare interests using the full picture, not NRI alone.
A recent royalty statement or check stub, a division order, and any deed or probate papers you have are the usual starting set. Confirm the decimal against the payor's files before relying on it.
