Working Interest vs. Royalty Interest: What You Actually Own in Each

The short answer

A working interest makes you a cost-bearing participant in an oil and gas operation: you pay your share of drilling and operating costs and receive your share of revenue after royalties. A royalty interest pays you a share of revenue off the top, free of those costs, but gives you no control and no drilling-related deductions.

Most confusion comes from the fact that both are described as ownership in oil and gas, and both produce monthly checks when wells are producing. The difference is where you sit in the chain between the rock and the revenue, and that position determines almost everything else: what you pay for, what you decide, what you can deduct and what you are responsible for if something goes wrong.

What a working interest is

A working interest is the ownership share that carries the right to explore, drill, produce and operate an oil and gas lease, and the obligation to pay a matching share of the costs of doing so. If you hold a 10% working interest, you generally pay 10% of the costs and receive 10% of the revenue left after royalties.

Working interests are created when a mineral owner leases their minerals to an operator. The lessee receives the operating rights, and those rights can then be divided among several parties. One of them usually acts as the operator, the company that runs day-to-day activity, hires contractors and files with state regulators. The others are non-operating working-interest owners, who fund their share and participate in major decisions under a joint operating agreement, commonly based on the American Association of Professional Landmen’s Form 610.

In practice, a working-interest owner receives two recurring documents. An authorization for expenditure (AFE) sets out the estimated cost of a proposed well or major operation before work begins. A joint interest billing (JIB) statement then bills each owner for their share of actual costs, typically monthly. Revenue statements arrive separately once the well is producing.

Summit Ventures structures its joint ventures around direct working-interest participation, which is why JV members hold governance rights and share in operational decisions. You can read more about how that works on the Opportunity page.

What a royalty interest is

A royalty interest is the right to a fraction of production revenue, paid before drilling and operating costs are deducted. Royalty owners do not fund wells, do not approve operations and are not responsible for operating liabilities. Their revenue depends entirely on how much the operator produces and at what price.

The most common royalty is the landowner’s royalty, which a mineral owner keeps when leasing their minerals. Lease royalty rates have historically ranged from one-eighth to one-quarter of production revenue, depending on the basin and the era in which the lease was signed. Royalty owners may still see certain post-production deductions, such as transportation or processing charges, depending on lease language and state law.

Two related interests are worth knowing:

• Mineral interest. Ownership of the minerals themselves. A mineral owner can lease, collect a signing bonus and retain a royalty. Once leased, the economic benefit is usually the royalty.
• Overriding royalty interest (ORRI). A royalty carved out of the working interest rather than the minerals. It is cost-free like a regular royalty, but it typically ends when the underlying lease ends.

Working interest vs. royalty interest: side by side

The core trade is simple: a working interest accepts costs, liability and involvement in exchange for a larger share of the economics and access to drilling-related deductions. A royalty interest gives those up in exchange for cost-free revenue with no operational role.

How revenue reaches each owner: an illustration

Revenue flows to royalty owners first. What remains is shared among working-interest owners according to their net revenue interest (NRI), which equals their working interest multiplied by the share of revenue left after all royalties.

This gap between the share of costs you pay and the share of revenue you receive is normal, and it is one of the first things to check in any offer. If a presentation quotes a working-interest percentage without the corresponding NRI, ask for it.

Costs and obligations that come with a working interest

A working-interest owner pays a proportional share of every cost the property incurs over its life: drilling and completion, equipment, monthly operating expenses, repairs and, eventually, plugging and abandonment. Royalty owners pay none of these.

The costs fall into four broad stages:

1. Drilling and completion. Estimated in the AFE, then billed as incurred. Actual costs can exceed the estimate.
2. Equipment. Casing, wellheads, pumping units, tanks and other surface equipment.
3. Lease operating expenses. Ongoing costs of keeping wells producing, such as electricity, chemicals, maintenance and field labor.
4. Plugging and abandonment. When a well reaches the end of its life, it must be plugged and the site restored to state standards. Working-interest owners share that cost.

Before committing to any working interest, ask how additional funding requests are handled, what happens if an owner does not meet one, and how the operator reports actual costs against estimates. Our Operator Due Diligence Checklist covers these questions in a printable format.

How the tax treatment differs

Royalty income is generally ordinary income that qualifies for percentage depletion. Working-interest owners can also qualify for depletion, and in addition may deduct intangible drilling costs and depreciate equipment, because they pay those costs directly. Under IRC Section 469(c)(3), deductions from a working interest held without limited liability may offset active income.

The main differences, in summary:

• Intangible drilling costs (IDCs). Under IRC Section 263(c), a working-interest owner can elect to deduct their share of IDCs in the year incurred. Royalty owners bear no drilling costs, so there is nothing to deduct. See Intangible drilling costs explained for when these deductions are large and when they are small.
• Percentage depletion. Under IRC Section 613A, qualifying independent producers and royalty owners may deduct 15% of gross income from the property, subject to volume and taxable-income limits. This one is available to both.
• The working-interest rule. Most losses from businesses you do not materially participate in can only offset similar income. Section 469(c)(3) carves out working interests held directly or through an entity that does not limit your liability. Royalty income is treated as portfolio income under the same section.
• Self-employment tax. Net income from a working interest held without limited liability can be subject to self-employment tax. Royalty income generally is not.
• Retirement accounts. Royalties are generally excluded from unrelated business taxable income under Section 512(b)(2). Working-interest income is not, which is one reason working interests are rarely held in IRAs.

High earners should also understand the excess business loss limit, which caps how much a net business loss can offset wages in a single year. We explain it in The excess business loss limit, explained for salaried professionals. None of this is tax advice for your situation, and a CPA should model any specific interest against your own tax filing.

If the numbers only work because of the deduction, they don’t work.

Control, liability and liquidity

Working-interest owners have a voice in major operational decisions and carry proportional liability for the operation. Royalty owners have neither. Both types of interest are far less liquid than publicly traded energy shares, and neither has a public market.

Control. Under a joint operating agreement, working-interest owners typically vote on significant decisions such as whether to drill a new well, rework an existing one or replace the operator. A non-consenting owner may face penalty provisions if they decline to fund an operation the others approve.

Liability. Because a working-interest owner participates in the operation, they share proportional responsibility for its obligations, including environmental and plugging obligations. This is the same feature that enables the favorable tax treatment described above, and it deserves a direct conversation with your own attorney, particularly if you have asset-protection planning in place.

Liquidity. Neither interest can be sold on an exchange. Royalty interests have a more established private market, while working interests are usually held for several years and transferred through negotiated sales. Some working interests can qualify as like-kind property for a 1031 exchange, subject to specific requirements.

Which one fits which situation

A royalty interest tends to suit someone who wants oil and gas revenue with no cost obligations or operational role. A working interest tends to suit someone who wants a larger share of the economics and the associated deductions, and is prepared to fund costs, accept liability and take part in decisions.

Rather than asking which is better, ask these questions:

• Could I meet additional cost requests without disrupting my plans?
• Am I comfortable with proportional liability, and have I discussed it with my attorney?
• Would the deductions actually be usable given my income type and the excess business loss limit?
• Do I want a role in decisions, or would I rather have none?
• Can I leave this capital committed for several years?
