The 405 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 12 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 Slaughter Estate Unit

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 low producing leases for this lease, from May 1, 2020. Its file does not give the rate, so we compare your stub with the full 4.6%. That is for August 2026.
Source: Texas Comptroller, approved severance tax exemptions.
Check the tax on your stub
Who buys the oil and gas?
Oil: Energy Transfer Company gathers it. Gas from oil wells: Occidental Permian Ltd. buys and 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, Occidental Permian Ltd., 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.

48 of the first 200 wells listed here are marked plugged in the Railroad Commission's wellbore records. 152 are not plugged. A plugged well is closed for good. A well that is not plugged can be put back on production, and its operator still owes the plugging.

SourceTexas Railroad Commission production records and full wellbore file. The first 200 by API number.

Other leases on these wells

The Railroad Commission files the same API numbers under one more lease too: a well keeps its number when it moves into a unit or is recompleted under another lease. A deed older than the unit may name one of them.

Who buys my oilOil price check

5,703.60 acres on the newest permit

  • Good to know

    The wells on this lease state different acreage

    The permits state between 604 and 5,704 acres. Use the acres from your own division order for the well you are paid on.

  • Good to know

    509 well completions are on file for this lease

    The count is of completions in the wellbore records, so a well completed more than once is counted each time. Each well can have its own unit. The decimal for one well does not have to equal the decimal for another.

  • 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.
