Your royalty statement is the single best document you own for getting an accurate estimate, if you know which lines to read.
Most owners get a royalty statement every month, glance at the check amount, and file it away. That statement is actually a dense, useful document, and three or four fields on it are exactly what a value estimate needs. This guide walks through a typical statement layout and shows you where to find the numbers that matter.
Layouts vary by operator, so field names will differ slightly, but the categories below appear on nearly every statement in one form or another.
Look for a field labeled decimal interest, interest owned, or division of interest. This is typically a long decimal, something like 0.00234567, representing your share of production from the well or unit. It is the single most important number on the page for an estimate, because it applies to every dollar of production before anything else is calculated.
If your decimal interest has changed from a prior statement, that usually signals a new well came online in the unit, diluting existing interests, or a title correction was processed. Either way it is worth noting.
Most statements break out oil in barrels and gas in mcf, along with a price received per unit for that month. Comparing this price against benchmark prices for the same period tells you whether the operator is getting reasonable market pricing or whether there is an unusually large gap that is worth asking about.
Volumes will move month to month with normal decline and with operational factors like downtime, so do not read too much into a single low month. A pattern across several months is more informative than any one statement.
Somewhere on the statement you will typically see deductions for gathering, transportation, processing, or compression, sometimes lumped together and sometimes itemized. These reduce your gross royalty down to a net payment, and the size of these deductions varies a lot by operator and by state, since some leases and some state laws limit what can be deducted from royalty.
If deductions look unusually large relative to your gross value, or if they appear for the first time on a well that has produced for years without them, that is worth raising with the operator directly.
Statements typically include a well name, an API number, and an internal property or owner number the operator uses to track your interest. Keep these on hand, since you will need them if you ever dispute a payment, request historical statements, or provide documentation to a buyer evaluating your interest.
If you own interests in multiple wells or units, each will typically appear as its own line or its own section on the statement, each with its own decimal interest and volumes.
A single statement tells a buyer very little. Six to twelve months of consistent statements, showing volumes, pricing, and payments over time, tells a much fuller story about how a well is actually performing and where it sits on its decline curve. If you are considering a sale, gathering a run of recent statements before you start the conversation puts you in a stronger position than handing over a single month and hoping it is representative. Many operators offer an online portal where past statements can be downloaded directly, which is usually faster than requesting paper copies by mail. If you switch to digital delivery, keep a habit of downloading each statement as it posts, since some portals only retain a limited history online before older records become harder to access.
