What owners ask about Darwin

When 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.

See your next three checks
Which Texas production tax rate applies?
The Texas Comptroller lists no approved exemption or reduced rate for this lease for August 2026, so the full 4.6% on oil and 7.5% on gas applies.
Source: Texas Comptroller, approved severance tax exemptions.
Check the tax on your stub
Who buys the oil and gas?
Oil: Bml, Inc. B gathers it. Gas from oil wells: Et Gathering & Processing LLC buys it; Energy Transfer Company gathers it. The buyer's price is what a royalty check is figured on.

See every buyer and past buyers
How many 1099s should an owner expect for 2025?
One company, Trilogy Operating, Inc., filed this lease's reports behind every 2025 check, so most owners get one form. The operator is not always the company that pays, so go by the name on the stubs.
