#What Is a Division Order?
A division order is a legal document that certifies the ownership interests in a producing oil or gas well and authorizes the operator to distribute revenue accordingly. It is, in practical terms, the document that tells the operator how to split the money. Every party with a financial interest in a well — mineral owners, royalty owners, working interest owners, and overriding royalty interest holders — should appear on the division order with a precisely calculated decimal representing their share of production revenue.
That decimal is commonly referred to as your Net Revenue Interest, or NRI. It is expressed as an eight-digit decimal (for example, 0.03125000) and determines the exact fraction of every dollar of production revenue that flows to you. Getting this number right is not a minor administrative detail. It is the single most important number in your oil and gas financial life.
Under Texas law, operators are required to distribute division orders in a timely manner. Specifically, Texas Natural Resources Code Section 91.402 requires operators to furnish division orders to all payees within 120 days after the first sale of production from a well, or within 60 days after a change in ownership that affects the distribution of proceeds. These are not suggestions — they are statutory requirements, and they exist to ensure that royalty owners are informed of their calculated interest and have the opportunity to verify it before payments begin.
#How Decimal Interest Is Calculated
Understanding how your NRI is derived requires walking through a straightforward but detail-sensitive calculation. Every step matters, because the final decimal is the product of several underlying fractions, and an error in any one of them cascades through to your check.
#The Basic Calculation
Suppose you own the mineral rights under 160 acres, and that acreage has been pooled into a 640-acre drilling unit. The operator's lease with you provides for a 1/8 royalty. Your mineral interest — before accounting for any additional burdens — is calculated as follows:
Mineral Interest = (Your Acreage / Unit Acreage) x Royalty Rate
Mineral Interest = (160 / 640) x (1/8) = 0.25 x 0.125 = 0.03125000
That 0.03125000 is your base royalty decimal. It means you are entitled to 3.125% of the gross revenue from the well, before any additional burdens are applied.
#Factoring in Burdens
In many cases, the base royalty decimal is not the final number that appears on the division order. Additional burdens may reduce your interest. If a prior owner reserved an overriding royalty interest when assigning the lease, or if there is a production payment carved out of your mineral estate, those burdens must be deducted to arrive at your true NRI.
For example, if there is a 0.005 overriding royalty interest burdening your tract, your NRI becomes:
NRI = 0.03125000 - 0.00500000 = 0.02625000
This is the decimal that should appear on your division order and that the operator uses to calculate your monthly payment.
#Understanding the Different Types of Interest
Division orders list several categories of ownership, and it is important to understand how they differ:
-
Royalty interest — The landowner's or mineral owner's share of production, free of the costs of drilling and operating the well. A royalty owner does not pay for well costs but receives a fraction of revenue as specified in the lease. In Texas, royalty rates typically range from 1/8 (12.5%) to 1/4 (25%), depending on the lease terms.
-
Working interest — The interest held by the party (or parties) responsible for drilling, completing, and operating the well. Working interest owners bear 100% of the costs of development and operations, and they receive whatever revenue remains after paying royalty owners and other burden holders. Working interest is not "free money" — it carries significant financial risk and ongoing expense obligations.
-
Overriding royalty interest (ORRI) — A royalty interest carved out of the working interest, not out of the mineral estate. Overriding royalties are typically created when a leaseholder assigns the lease to an operator and retains a small percentage of revenue as compensation. Like a royalty interest, an ORRI is free of operating costs. Unlike a royalty interest, it expires when the underlying lease expires.
Each of these interests appears as a separate decimal on the division order, and together they must account for 100% of the well's revenue — that is, all decimals on a division order should sum to 1.00000000.
#Why Division Orders Matter
#They Determine How Much You Get Paid
Your division order decimal is applied to every dollar of revenue the well generates for as long as you own your interest. Even a seemingly trivial error compounds relentlessly over time.
Consider this example: a well produces $50,000 per month in gross revenue. If your NRI is incorrectly stated as 0.03100000 instead of the correct 0.03200000 — a difference of just 0.001 — you are underpaid by $50 every single month. That is $600 per year. Over 30 years of production, which is not unusual for a well in the Permian Basin or Eagle Ford Shale, that single decimal error costs you $18,000. And that is on just one well. Mineral owners with interests in multiple wells can multiply the impact accordingly.
#They Are a Snapshot in Time
A division order reflects ownership as of a specific date. When ownership changes — through inheritance, sale, gift, or assignment — the operator should issue a new division order reflecting the updated interests. In practice, this does not always happen promptly. If a mineral owner passes away and the estate is probated, there can be a significant lag before the operator updates its records and issues revised division orders to the heirs. During that gap, payments may be suspended or directed to the wrong party.
#Signing Does Not Change Your Rights
This is one of the most misunderstood aspects of division orders in Texas, and it is worth stating clearly: under Texas Natural Resources Code Section 91.402(h), signing a division order does not amend, change, or otherwise affect your rights under your mineral deed or oil and gas lease. A division order is a statement of the operator's calculation of your interest — it is not a contract that alters the underlying terms of your ownership.
This statutory protection exists because, historically, some operators included language in division orders that attempted to modify lease terms, such as introducing post-production cost deductions that the lease did not authorize. The Texas Legislature addressed this by making clear that division orders cannot serve as instruments to change the substantive rights of interest owners. If you believe a division order misstates your interest, you should not refuse to sign it as a negotiation tactic — instead, sign it under protest and pursue correction through the operator's division order department.
#Common Division Order Problems
Even well-intentioned operators make mistakes in the division order process. Title to mineral interests in Texas and other producing states can be extraordinarily complex, involving chains of conveyance stretching back a century or more. The most common problems include:
#Incorrect Tract Descriptions or Acreage Calculations
If the division order analyst miscalculates the net acres attributable to your interest — perhaps by using the wrong survey or failing to account for a partial conveyance — your decimal will be wrong from the start. This is especially common in areas with irregular surveys or where tracts have been subdivided multiple times over generations.
#Failure to Account for Prior Conveyances or Reservations
Mineral estates in Texas are frequently severed from the surface estate, and mineral interests are often further subdivided through successive conveyances. If a prior owner reserved a fraction of the minerals when selling the surface, and the division order analyst misses that reservation in the chain of title, the resulting decimal will overstate one party's interest and understate another's.
#Probate Not Properly Reflected
When a mineral owner dies, their interest passes to heirs according to their will or, if there is no will, under the state's intestacy laws. Until the estate is probated and the operator receives documentation (such as letters testamentary, an affidavit of heirship, or a court order), the operator may not know how to allocate the deceased owner's interest. This can result in payments held in suspense indefinitely, or in division orders that still reflect the deceased owner's name long after the estate has been settled.
#Pooling or Unitization Not Properly Applied
When a well is drilled on a pooled or unitized tract, the division order must correctly reflect each owner's proportionate share within the unit. Errors arise when the unit boundaries are not properly delineated, when amendments to the pooling designation are overlooked, or when an owner's acreage is attributed to the wrong unit.
#Overriding Royalties Incorrectly Deducted
Overriding royalty interests must be deducted from the working interest, not from the royalty interest. If an ORRI is mistakenly applied as a burden against the mineral owner's royalty, the mineral owner's NRI will be understated and they will be underpaid.
#How to Verify Your Division Order
When you receive a division order — whether for a new well or following a change in ownership — do not simply sign and return it. Take the time to verify the decimal independently. The following five-step process will help you catch most common errors.
#Step 1: Review the Legal Description Against Your Deed
Compare the legal description on the division order (the survey name, abstract number, county, and tract description) to the legal description in your mineral deed or lease. They should match. If the division order references a different survey or abstract, that is an immediate red flag.
#Step 2: Verify the Unit Size and Your Proportionate Share
Confirm the total acreage of the drilling or pooling unit. Then verify how many net mineral acres you own within that unit. Your proportionate share is your net acres divided by the total unit acreage. If you are uncertain about the unit boundaries, request a copy of the pooling designation or unit plat from the operator.
#Step 3: Check for Burdens Against Your Title Abstract
Obtain your title abstract or title opinion and review it for any burdens on your interest — overriding royalties, production payments, or other encumbrances. These should be reflected in the division order calculation. If they are not, your decimal may be overstated (which will eventually be corrected, potentially resulting in a recoupment from future payments).
#Step 4: Confirm the Royalty Rate Matches Your Lease
Verify that the royalty rate used in the division order calculation matches what your lease specifies. If your lease provides for a 3/16 royalty and the division order was calculated using 1/8, your decimal is wrong.
#Step 5: Compare the Final Decimal to Your Own Calculation
Using the information gathered in the previous steps, calculate your own NRI:
(Your Net Mineral Acres / Total Unit Acres) x Royalty Rate - Any Burdens = Your NRI
If your calculation does not match the decimal on the division order, you have a discrepancy that needs to be resolved before you sign.
#What to Do If Your Division Order Is Wrong
Discovering an error on your division order is not uncommon, and the process for correcting it is well-established. Here is how to proceed.
#Contact the Operator in Writing
Send a written communication — email is acceptable, but a certified letter creates a verifiable record — to the operator's division order department. Identify the well by name and API number, state the decimal you believe is incorrect, provide your own calculation, and request a review. Be specific and factual.
#Provide Supporting Documentation
Attach copies of the relevant documents: your mineral deed, your lease, the pooling designation, and any title opinions or abstracts you have. The more documentation you provide upfront, the faster the operator can evaluate your claim. Division order analysts are working from the same chain of title you are — giving them the missing piece often resolves the issue quickly.
#Know Your Rights Under Texas Law
Texas Natural Resources Code Section 91.403 requires operators to respond to written inquiries from interest owners regarding payment within 30 days. If you have submitted a documented claim and the operator fails to respond within that statutory window, you have additional remedies available, including the right to pursue the matter through the Railroad Commission of Texas or through civil litigation.
#Consider Professional Help for Complex Issues
If the title issue is genuinely complex — involving contested heirship, multiple fractional conveyances, or disputes about the validity of prior instruments — you may need to engage a landman to run a fresh title check or retain a title attorney to issue an updated title opinion. The cost of professional title work is a worthwhile investment when the decimal error represents thousands of dollars in cumulative underpayment.

#Take Control of Your Division Order
Your division order is not just another piece of paperwork to sign and forget. It is the document that governs every royalty payment you will receive from a well for as long as you hold your interest. Verifying that your decimal is correct — and correcting it when it is not — is one of the highest-return activities available to any mineral owner.
The challenge is that manual verification requires gathering documents from multiple sources, performing precise calculations, and tracking changes over time across potentially dozens of wells. It is exactly the kind of detail-intensive, high-stakes work where human error is most likely and most costly.
