Production

Month by month, from the state record

What the Railroad Commission says this oil lease produced. Oil is in barrels (bbl). Gas is in thousand cubic feet (mcf).

No production to chart

The state shows zero oil and zero gas for all 36 months we hold (Aug 2023 to Jul 2026). A lease that is shut in or newly reported looks like this. The ledger below lists each month.

Gas disposition

Where the gas went

Every month the operator tells the state where each mcf of gas went, using a code. The code decides how your gas is paid.

No gas disposition reported for this lease

The operator has not reported where the gas went in the months we hold.

Operator history

Who has run this lease

The operator runs the wells and pays your royalty. When the operator changes, payments often slip for a month or two.

The operator changed once, most recently in May 2026

If your statements skip or shrink around a change, ask the new operator's owner relations department whether the month is in suspense.

Your tract may share its production with neighbours in a pooled unit. The unit acres the operator uses to divide production can differ from the acreage on one permit.

33 wells are listed on this lease

Each well can have its own unit. The decimal for one well does not have to equal the decimal for another.

Check my decimal against the unit

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 BLOCK 31 UNIT sold each month.

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

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.

Ledger

36 months, newest first

Compare these numbers with your statements. Your share of a month is the “Oil sold” volume times your decimal. Scroll sideways on a phone.

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.
