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 25 months we hold (Jan 2020 to Jan 2022). 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.

Wells

Wells on this lease

Every well the Railroad Commission links to oil lease 14165 in district 01. The API number is the state’s ID for a well.

No wells are linked to this lease in our data

Older leases and some gas wells are filed without well records. Production is still reported at lease level, so the charts and ledger on this page are unaffected.

Who buys and gathers

Who moves and buys this lease's production

The operator files a Form P-4 with the Railroad Commission naming the companies authorised to gather and buy the oil and gas. The buyer's price is the one your royalty is figured on.

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 HALFF & OPPENHEIMER 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.

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 Jan 2022?

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.
