Gas disposition
Where the gas went
Since Apr 2026 the lease's gas goes to a transmission line instead of lease fuel
Where gas goes decides how it is paid: processed gas can carry plant products and processing fees, gas sold straight to a pipeline usually does not. Flaring peaked at 50.0% of the gas in Oct 2025.

SourceTexas Railroad Commission Production Data Query, gas disposition by code, lease 15844, district 01. Reported through Jul 2026.
Transmission line (2)
Sold straight into a pipeline without processing. Processing fees on your statement would be worth asking about.
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 11 months reported, 7.8% of the gas was flared. 5 months went above 3%, which we mark in the ledger below.

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.
