The first royalty check is a moment most mineral owners look forward to — until they try to read the statement attached to it. A typical royalty remittance looks like an accounting spreadsheet designed by people who preferred not to be understood: product codes, decimal interest, gross value, severance tax, and a column of deductions with names like "GPC" or "T&F." This guide walks through each piece.
The check amount is only the end of the calculation. Understanding what happened before it tells you whether you were paid correctly — and whether you've been leaving money on the table every month.
Your decimal interest: the most important number on the page
Near the top of the statement you'll find a decimal like 0.00520833. This is your royalty interest — the fraction of all production revenues from your well that flows to you. It's calculated from your net mineral acres in the unit, the total unit acreage, and your lease royalty rate. A small error here — a clerical mistake, a miscalculated unit boundary — cuts your check by a fixed percentage forever. Every new owner should verify this number against their division order and their lease before depositing anything.
Gross value and how it becomes net value
The gross value line shows what the gas or oil sold for before any deductions. The gap between gross value and what lands in your check is where the complexity lives:
- —Severance tax — a state production tax (Pennsylvania charges 1.8% of market value via its impact fee structure; West Virginia charges 5% for gas, 5% for oil). This is legitimate and appears on every statement.
- —Post-production deductions — gathering, compression, processing, and transportation costs between the wellhead and the sales point. Whether operators can charge these to royalty owners depends almost entirely on your lease language. Many PA and WV owners are paying these without realizing their lease may prohibit it.
- —Marketing or administrative fees — a softer category. Some are legitimate; others are padding. An unusually large "admin" line deserves a written request for detail.
Product codes and BTU adjustments
Gas wells produce multiple products, and each gets its own line: dry gas (GAS), natural gas liquids stripped at the processing plant (NGLs, C3, iC4, nC4, C5+), and sometimes condensate. If your area produces wet gas — as much of southwestern Pennsylvania and West Virginia does — the NGL lines can represent significant value. Missing or incorrectly calculated NGL royalties are one of the most common sources of underpayment. If you see only a single "GAS" line on a wet-gas well, ask why.
BTU content also matters: higher-BTU gas can sell at a premium. Your statement may show a BTU adjustment factor; if the raw Mcf volume looks right but the value seems low, the BTU figure is worth checking against the operator's monthly test reports.
Volume: are the Mcf numbers believable?
Your check covers a specific calendar month, and the volume line shows how many Mcf (thousand cubic feet) of gas — or barrels of oil — the well produced that month, attributed to your interest. Production from new horizontal wells often falls rapidly in the first year, so month-to-month variation is expected. What isn't expected: a volume that seems implausibly low for a well you know has been producing, or a month that goes missing entirely. Operators are required to report production volumes to state regulators; in Pennsylvania those records are public. If the volume on your check doesn't match the state's production data, something is wrong.
What to do if the numbers don't add up
- —Request a written explanation of any deduction you don't recognize. The operator is required to provide one.
- —Pull the state production data for your well and compare volumes. Pennsylvania DEP and West Virginia DEP both publish well-level production records.
- —Compare your decimal interest to the decimal on your division order. A mismatch is an error in your favor or against you.
- —Look at twelve months of statements, not one. Underpayment patterns — a deduction that grows over time, NGL volumes that disappear — are easier to see across a run of months than in a single check.
If something looks wrong and you can't get a straight answer from the operator, that's the work we do at Oliver Natural Resources: compare your statements against production data, audit your lease terms against the deductions being taken, and — when underpayment is clear — pursue what you're owed. A royalty audit costs you nothing unless we recover money. Request one here or call us. Call us before you sign anything — including any settlement of a royalty dispute.
