The 6 ringed dots are this lease's wells, each where the Railroad Commission's map puts it. The other dots are wells and drilling permits of the last 24 months on the land around it; the counts are for everything in the picture, which is about 6 miles across. The thin brown lines are the original land surveys; where there is room, a survey carries its abstract number, the number deeds and division orders cite.

From the state record

What owners ask about Act E

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.
Source: Railroad Commission production reports; Texas Natural Resources Code §91.402.
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: Valero Marketing and Supply Co. gathers it. Gas from oil wells: Enterprise M B Midstream LLC buys it; Enterprise Products Operating LLC gathers it. The buyer's price is what a royalty check is figured on.
Source: Railroad Commission Form P-4, gatherers and purchasers.
See every buyer and past buyers
How many 1099s should an owner expect for 2025?
One company, Diamondback E&P LLC, 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.

520.20 acres on the newest permit

  • Worth asking

    An allocation well is on this lease

    A well drilled across several tracts shares its production by an allocation formula, so the decimal is not always your acres over the unit acres. Ask the operator for the allocation formula and the tract factor for your land.

  • Worth asking

    A Rule 37 case is listed

    The RRC permit records list a Rule 37 case. This does not establish your royalty share. Ask for the permit and unit plat for your well.
