How to read this page
Questions owners ask
What is a decimal interest?
It is your share of the whole lease, written as a decimal. A 1/4 royalty on 5 net acres in a 1,280-acre unit is 1/4 × 5 ÷ 1,280 = 0.00097656. Your division order states yours.
How do I use this page to check a royalty check?
Take the “Oil sold” volume for the month the check covers and multiply it by your decimal. The answer should match the barrels on your statement. If it does not, upload the statement and we will show where the two differ.
Why is the newest month Jun 2026?
The Railroad Commission publishes production two to three months after the fact and revises recent months. We re-pull the latest three months on every update.
Does this page show what my check should be?
No. It shows what the state recorded. Prices, fees and taxes depend on your lease and on what your operator gets for the oil and gas. The estimator gives a ceiling to compare against.
