Verify the decimal on a division order before you sign it, or run the decimal on a check stub backward to find out how many net mineral acres you actually own.
Net acres ÷ unit acres × royalty rate. Use it to verify what the operator sent you.
If the decimal on your division order doesn't match, don't sign it yet. Here's why.
All you have is the decimal on a check stub or division order? Run it backward to your net mineral acres and net royalty acres.
NMA = decimal × unit ÷ royalty ÷ allocation. NRA = decimal × unit ÷ 1/8 ÷ allocation. On a multi-unit horizontal well, your decimal is scaled by the share of the lateral in your section; that share is the allocation factor, printed on the division order.
The usual culprits, in order: a multi-unit horizontal well scaling your decimal by an allocation factor, a different royalty rate than you assumed (check the lease, not your memory), fewer net acres than the family believed after generations of splits, or a plain operator error. The math itself is one line: net acres divided by unit acres times royalty. If your numbers will not reconcile with the operator's, our letter generator includes a decimal dispute letter, and the net mineral acres calculator helps you pin down the acreage side first.
Send us the division order or check stub and we will reconcile it against the county records, free, whether or not you ever sell. All thirteen tools live on the calculators page.
