All of the gas went to a processing plant in the last 12 months

Processing plant (3)

Sent to a gas plant that pulls out natural gas liquids. Your statement should show plant products, and may show processing fees.

Lease fuel (1)

Burned to run equipment on the lease. Not sold, so it pays no royalty. A few percent is normal.

Flared (4)

Burned off or vented, not sold. It pays no royalty. More than 3% in a month is worth watching.

None of the gas was flared in the last 12 months.

Unit and wells

480 acres on the newest permit

Acres and wells as the operator filed them on its Railroad Commission drilling permits. Your decimal is your net acres over the unit acres, so this is the number to hold your division order against.

An allocation well is on this lease

A well drilled across several tracts shares its production by an allocation formula, so the decimal is not always your acres over the unit acres. Ask the operator for the allocation formula and the tract factor for your land.

Estimator

Estimate your royalty for this lease

A rough check before you look at a statement: the state volumes times your decimal, priced at WTI and Henry Hub.

Estimator

What could your check be?

Your decimal interest is the small number on your division order that says what share of the whole lease (8/8ths) is yours. Type it in and we apply it to what the state says HAM C1 sold each month.

For example 0.00097656, or a fraction like 1/1024.

Dollars per barrel. Your statements show the gap your operator uses. Leave 0 to price oil at WTI.

Your estimate appears here

Enter your decimal to see an estimated royalty for each of the last 12 months this lease reported. Nothing you type leaves your browser.

An estimate, not your check

It ignores gathering and processing fees, taxes, plant products and the price your operator actually gets, so your statement will differ. Use it as a ceiling to compare against. Regional gas prices are often below Henry Hub.

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 Jul 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.
