What owners ask about Thunderstruck
01When is the check for August 2026 due?
August 2026 is the newest month the state has posted for this lease. Texas law gives the payor until 60 days after the end of the sale month for oil and 90 for gas: the oil by Oct 30, 2026 and the gas by Nov 29, 2026, unless the lease sets another time.
Source: Railroad Commission production reports; Texas Natural Resources Code §91.402.
The Texas Comptroller lists flared gas for this lease, from Dec 1, 2018. Its file does not give the rate, so we compare your stub with the full 7.5%. That is for August 2026.
Oil: Stakeholder Ms Crude Oil Pl LLC, Oasis Transp & Marketing Corp. and Sentinel Transportation, LLC gather it. Gas from oil wells: Stakeholder Gas Services, LLC buys it; Stakeholder Gas Utility, LLC gathers it. The buyer's price is what a royalty check is figured on.
Source: Railroad Commission Form P-4, gatherers and purchasers.
Two companies filed this lease's reports behind 2025 checks: Steward Energy II, LLC and Burk Royalty Co., Ltd.. An owner paid by more than one of them gets a form from each. The operator is not always the company that pays, so go by the names on the stubs.
