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.

58% of the gas went to a processing plant in the last 12 months

Flaring peaked at 54.3% of the gas in Aug 2025.

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.

Over the last 12 months, 20.2% of the gas was flared. 22 months went above 3%, which we mark in the ledger below.

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 MZYK NORTH UNIT 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.

FAQ

Questions about MZYK NORTH UNIT

Who operates the MZYK NORTH UNIT lease?

The Railroad Commission lists Caturus Energy, LLC (operator number 103593) as the operator of this lease in Karnes County, Texas. The operator history on this page shows earlier operators and when the record changed.

How much has the MZYK NORTH UNIT lease produced?

The lease reported 114,427 bbl of oil and 182,111 mcf of gas in the last 12 months through Jul 2026. Monthly figures for 27 months are in the ledger on this page, taken from the Railroad Commission's production data.

Does this page show who owns the royalty?

No. Railroad Commission records show who operates a lease and what it reported, not who owns the minerals or receives royalty. Your division order and royalty stub name the lease and your decimal interest.

How do I check my royalty stub against this lease?

Multiply the lease's volume for a month by your decimal interest and compare it with the barrels and mcf on your stub for the same month. The two are seldom identical, since sales and reporting months can differ, but a large gap is worth a question to the operator.
