The Mineral Rights Terms
Every Landowner Should Know

What it is

A Pugh clause limits a production lease to only the acreage actually being drilled — it prevents the operator from holding all of your land with a single producing well on a small part of it.

Why it matters

Without one, an operator can drill one well on 5 acres and legally hold the other 95 acres of your land indefinitely. You receive no additional bonus and cannot lease those acres to anyone else during the entire primary and secondary term.

What ONR does

We insist on a meaningful Pugh clause — including depth restrictions — in every lease we negotiate. It is one of the highest-value protections we routinely add.

What it is

Post-production deductions are costs the operator takes out of your royalty check for gathering, compressing, processing, transporting, and treating the gas after it leaves the wellhead.

Why it matters

These deductions can reduce your royalty payment by 20–40%. A lease that says '18% royalty' but allows unlimited post-production deductions can pay out far less than a '15% royalty at the wellhead' with no deductions.

What ONR does

We fight to get deductions excluded from the royalty calculation entirely — or capped and clearly defined. The difference in lifetime royalties can be substantial.

What it is

The royalty rate is the percentage of production revenue you receive from your leased minerals. A 15% royalty means the operator keeps 85 cents of every dollar and sends you 15 cents — before any deductions.

Why it matters

Even a 1–2 percentage point improvement in royalty rate can mean tens of thousands of dollars over the life of a well. The operator's first offer is almost never their best.

What ONR does

We routinely negotiate royalty rates from 15% up to 18–20% depending on formation, county, and competition in the area. We know what comparable deals look like and use that to push yours higher.

What it is

The bonus is the upfront cash payment you receive when you sign an oil and gas lease. It is typically quoted per acre and paid regardless of whether the operator ever drills a well.

Why it matters

The bonus is the one guaranteed payment in any lease. Operators often start with a low number because most landowners accept it without negotiation. The market value is often 2–3× or more than the initial offer.

What ONR does

We bring competing buyers to your deal and leverage market knowledge to push bonuses well above the opener. In one recent transaction, we took a landowner's bonus from $3,500 to $6,000 per acre.

What it is

The primary term is the fixed initial period of the lease — typically 3–5 years — during which the operator has the right to drill. If no well is producing by the end of the primary term, the lease expires (unless it contains an extension clause).

Why it matters

A longer primary term means the operator can sit on your acreage for years without drilling. You're locked out of re-leasing at potentially higher future rates. Shorter terms keep you in control.

What ONR does

We push to shorten primary terms and remove automatic extension options. A 3-year term is our standard starting point wherever the market will support it.

What it is

A shut-in provision allows an operator to maintain your lease beyond the primary term by paying a small per-acre rental fee — even when the well is not actually producing. The well is 'shut in' (temporarily idle).

Why it matters

Weak shut-in provisions let operators hold your minerals for years at token payments — $1–3 per acre — while production is suspended. A strong shut-in clause limits how long this can happen and sets meaningful payment terms.

What ONR does

We negotiate shut-in clauses with strict time limits (typically 60–90 days cumulative) and require the operator to actually restore production or release the lease.

What it is

A depth clause limits the lease to specific geological formations or depths. Without one, a single lease can cover every mineral formation beneath your land — even those the operator has no intention of developing.

Why it matters

If you lease your Utica Shale rights but the operator has no plan to ever drill the Marcellus above it, a lease without a depth clause ties up both formations. You can't lease the Marcellus to someone else who would develop it.

What ONR does

We routinely add formation-specific or depth-limited restrictions to ensure you retain the right to negotiate separately for formations not targeted by the current operator.

What it is

Surface use clauses define what the operator is allowed to do on top of your land — where they can build roads, lay pipelines, erect equipment, use water, and cut timber — in connection with their drilling operations.

Why it matters

Broad surface use rights in a lease can allow operators to fundamentally alter your land with little notice and no compensation. In some states, mineral rights dominate surface rights, which makes this even more important.

What ONR does

We push hard on surface use restrictions: requiring written notice, limiting disturbance areas, requiring reclamation bonds, and restricting use of surface water. These provisions matter enormously if you live on or farm the land.

What it is

Pooling combines multiple small tracts or mineral interests into a single drilling unit. Unitization does the same at a larger scale across a full field. Your royalty is then based on your proportionate share of the unit, not the whole well.

Why it matters

Operators use pooling to satisfy spacing requirements and may combine your acreage with neighbors'. Without protections, your royalty can be diluted significantly by how the unit is structured.

What ONR does

We negotiate pooling clauses carefully — setting maximum unit sizes, requiring your consent for any pooling beyond basic statutory requirements, and protecting your royalty from being diluted by unfavorable unit configurations.

What it is

Mineral rights and surface rights can be owned separately. Mineral rights give you ownership of what's underground — oil, gas, coal, and other subsurface resources. Surface rights cover the land above. One person can own both; they can also be split ('severed').

Why it matters

Many families inherit land without realizing their ancestors sold the mineral rights decades ago — or vice versa. Understanding what you own is the essential first step before any negotiation or transaction.

What ONR does

We help clients confirm exactly what they own before any offer is evaluated. Title examination is part of our process so no one is surprised at closing.

What it is

A working interest is a share of ownership in a well that comes with both the right to produce and the obligation to pay a proportionate share of drilling and operating costs. This is what the oil company holds — not you.

Why it matters

As a mineral owner (royalty interest), you receive a share of production revenue without bearing any drilling or operating costs. Understanding the distinction clarifies your rights and protects you from agreements that try to pass costs through.

What ONR does

We make sure royalty agreements never accidentally include language that could expose you to production costs — a mistake that occasionally appears in poorly-drafted leases.

What it is

A royalty interest (RI) is tied to the land and runs with your ownership. An overriding royalty interest (ORRI) is carved out of the working interest and is only valid as long as the underlying lease is in force. When the lease expires, an ORRI disappears.

Why it matters

Some buyers or intermediaries will offer you an ORRI instead of purchasing your mineral rights outright. An ORRI sounds like a royalty — but it has no permanent connection to your land and evaporates when the lease does.

What ONR does

We identify and flag these distinctions so you understand exactly what you're being offered and what you'd be giving up. Permanent mineral ownership is almost always more valuable than an ORRI.

What it is

A force majeure clause excuses the operator from obligations — including lease expiration — when extraordinary events outside their control (weather, government action, market disruptions) make performance impossible.

Why it matters

Operators sometimes invoke force majeure broadly to extend leases during market downturns. Without clear limits, a lease that should have expired can be held open indefinitely while you wait and cannot re-negotiate.

What ONR does

We tighten force majeure language to define triggering events narrowly and set strict time limits on any suspension, protecting your right to reclaim your minerals if the operator can't or won't develop them.

What it is

A lease is 'held by production' when a producing well extends the lease beyond its primary term — for as long as production continues in paying quantities. There is no fixed end date; the lease survives as long as the well does.

Why it matters

HBP is how a single well drilled decades ago can still control every acre a family owns today. Combined with a lease that lacks a Pugh clause, one marginal well can lock up hundreds of acres indefinitely at terms negotiated generations ago.

What ONR does

We examine whether production is genuinely in 'paying quantities' — marginal wells are sometimes kept barely alive purely to hold acreage. Where an HBP claim is weak, there may be an opportunity to break the lease and renegotiate at today's rates.

What it is

A delay rental is a small annual payment — often just a few dollars per acre — that allows the operator to postpone drilling during the primary term without losing the lease.

Why it matters

Delay rentals let an operator sit on your acreage for years at trivial cost while you wait. In older 'unless' leases, the structure can also create traps around payment timing that have spawned decades of litigation.

What ONR does

We prefer paid-up leases where the full consideration comes as bonus at signing — no annual dribble of small checks, no ambiguity, and no incentive for the operator to warehouse your acreage cheaply.

What it is

A division order is a document the operator sends before paying royalties, stating your decimal share of production revenue from a well or unit. Signing confirms you agree with their calculation of your interest.

Why it matters

An incorrect decimal costs you money on every check for the life of the well — and errors are more common than most owners assume. A division order also cannot legally amend your lease, though poorly drafted ones sometimes include language that tries.

What ONR does

We verify the decimal against your deed, lease, and unit designation before you sign, and strike any language that attempts to modify lease terms. It takes us minutes and protects every royalty check you'll ever receive.

What it is

Net revenue interest is your actual decimal share of a well's production revenue after all burdens are accounted for — calculated from your acreage in the unit, your ownership fraction, and your royalty rate.

Why it matters

NRI is the number your money actually flows through. Two neighbors with identical acreage can have very different NRIs because of royalty rates, ownership splits, or unit boundaries — and a miscalculated NRI silently shorts you on every payment.

What ONR does

We calculate your NRI independently rather than trusting the operator's math, and reconcile it against your royalty statements. When the numbers don't match, we pursue correction and back payment.

What it is

A top lease is a new lease signed while an existing lease is still in force, taking effect only if and when the existing lease expires. Companies use top leases to lock up acreage they expect to become available.

Why it matters

If someone offers you a top lease, it's a strong signal they believe your current lease is about to expire — and that your minerals are worth competing for. That knowledge is leverage most owners don't realize they have.

What ONR does

We treat top lease interest as market intelligence. If one company wants to top-lease your acreage, others likely will too — so we run a competitive process rather than letting the first mover set the price.

What it is

An extension or option clause gives the operator the unilateral right to extend the primary term — typically for a second term of equal length — by paying an additional bonus, often at a rate fixed years earlier.

Why it matters

A 5-year lease with a 5-year extension option is really a 10-year lease. If market rates double during the first term, the operator still extends at the old fixed price — and you have no say in it.

What ONR does

We push to remove extension options entirely. If the operator insists, we demand the extension bonus float to market rates at the time of extension — not the rates from years earlier.

What it is

A warranty clause makes you legally guarantee that you own clean title to the minerals you're leasing — and obligates you to defend that title, at your expense, if anyone challenges it.

Why it matters

Mineral title in Appalachia is frequently tangled by centuries of splits and conveyances. A general warranty can make you personally liable for title defects created generations before you were born.

What ONR does

We strike warranty clauses or reduce them to 'quitclaim' language — you lease whatever you own, without personally guaranteeing a chain of title you didn't create and can't control.

What it is

A free gas clause entitles the landowner to use a set amount of gas from a well on the property for household purposes at no cost — a traditional feature of many older Appalachian leases.

Why it matters

Free gas can be worth thousands of dollars a year to a rural household, but modern leases quietly omit it, and operators sometimes resist honoring it in older leases through metering disputes and liability requirements.

What ONR does

Where a well will sit on your property and you want free gas, we negotiate for it explicitly — with clear volume, measurement, and maintenance terms so the benefit survives operator changes.

What it is

A market enhancement clause is a softer-sounding cousin of the deduction clause: it prohibits deductions for making gas marketable, but allows them for costs that 'enhance' the value of already-marketable gas.

Why it matters

The line between 'making marketable' and 'enhancing value' is where your royalty disappears. Operators interpret these clauses aggressively, and what sounds like a no-deductions lease can still leak 10–25% of your royalty.

What ONR does

We treat market enhancement language as a red flag, not a protection. We negotiate for true gross-proceeds royalties with deductions flatly excluded — and clearly defined if any must remain.

What it is

Minerals are 'severed' when their ownership was split from the surface at some point in the chain of title. A title opinion is a professional examination of county records that establishes who actually owns what today.

Why it matters

In western Pennsylvania, severances from the 1800s oil boom still govern ownership today. Families routinely discover they own less — or more — than they believed. Every serious transaction stands or falls on title.

What ONR does

Title examination is part of our process before any deal is evaluated. We find the gaps, heirship questions, and old reservations before closing — when they're still fixable — not after, when they're expensive.

What it is

An NPRI is a carved-out right to receive a share of royalty income without the right to lease, negotiate, or collect bonus payments. The holder 'participates' in royalties only — someone else controls the leasing decisions.

Why it matters

NPRIs are created — sometimes accidentally — in deeds and inheritances, and they complicate both selling and leasing. If you hold one, your income depends entirely on a lease you had no voice in negotiating.

What ONR does

We identify NPRIs and other fractional interests during title review, explain exactly what each party controls, and structure transactions so every interest holder understands what they're entitled to.

What it is

A right of first refusal gives a party the option to match any competing offer before you can accept it. In mineral documents, buyers and operators sometimes insert ROFRs in their own favor.

Why it matters

A ROFR held against you quietly kills your negotiating leverage: serious buyers won't spend effort on an offer that an insider can simply match, so competition — and price — evaporates before it starts.

What ONR does

We strike ROFRs that run against you and flag any existing ones during document review. Your minerals are worth more when every buyer knows the process is genuinely open.

What it is

An assignment clause governs whether and how the operator can transfer your lease to another company. Unrestricted assignment means your lease can be sold to anyone — including a thinly capitalized operator you've never heard of.

Why it matters

The company you negotiated with may not be the company you end up with. Leases are traded constantly, and obligations like royalty payment, surface care, and plugging wells are only as good as the company that ends up holding them.

What ONR does

We negotiate notice requirements for assignments and, where possible, continuing liability for the original lessee — so the operator who made you promises can't simply sell them away.
