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.

99% of the gas went to a transmission line in the last 12 months

Flaring peaked at 66.6% of the gas in Dec 2024.

Transmission line (2)

Sold straight into a pipeline without processing. Processing fees on your statement would be worth asking about.

Flared (4)

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

Over the last 12 months, 0.5% of the gas was flared. 3 months went above 3%, which we mark in the ledger below.

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.

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 RAPIER 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.
