A remittance statement is the same arithmetic on every operator's paper, dressed up in different columns. Once you can see the pattern you can check a stub in a minute — and you will notice the month a well was left off or a deduction quietly doubled.
Volume and price. Barrels (oil) or mcf (gas) sold for the production month, and the price per unit. Multiply them and you have gross value for the well.
Your decimal interest. A number like 0.00234375, printed once per property. It is your fraction of the minerals × your royalty rate × the tract's share of the spacing unit. If the decimal changes without a letter explaining why, ask.
Taxes. Wyoming charges a severance tax on oil and gas production and the counties charge ad valorem (property) tax on the same production; both are withheld from royalty owners in proportion to their interest. They show up as separate lines and together commonly take a low-teens percentage off the top.
Deductions. Gathering, compression, processing, transportation and marketing. Whether these can be charged against your royalty at all depends on your lease language and the type of interest you hold, so read the lease before you accept them.
Net. Gross − taxes − deductions, times your decimal (or the decimal applied first — operators differ), summed over every well on the stub. It must equal the check.
Wyoming's royalty-payment statute (W.S. §§ 30-5-301 to 30-5-305) sets deadlines for the first payment after a well starts selling and for payments after that, and it provides interest when an operator pays late without a good reason. If a check is months overdue, a letter citing the statute usually gets a reply.
A spreadsheet with one row per stub line — well, month, volume, price, gross, tax, deductions, net — is the single best tool a royalty owner has. It makes 1099 season trivial, shows decline at a glance, and turns "the check seems small" into "well X paid 40% less than last month at the same price."
The 1099-MISC reports gross royalty before taxes and deductions, and it is by check date rather than production month. Reconciling it needs the year's stubs added up line by line.
It depends on the lease. Some Wyoming leases are 'cost-free' at the wellhead; many older ones are silent. Read the royalty clause and, if it is ambiguous, get advice before signing a division order that ratifies the deductions.
A statement from the operator of the decimal interest it believes you own in a well or unit. Signing it confirms the decimal for payment purposes; it does not change your title. Check the arithmetic against your fraction, royalty rate and tract acreage before you sign.
