The 15 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.

1 lease in Martin County in the same field or with the same operator carries the Cyclops 1-30 name. Operators often name the leases on one family's land alike, with a letter or unit number after the name. Sharing a name proves no tie: your division order says which ones pay you.

What owners ask about Cyclops 1-30 Unit 2

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: Medallion Operating Company, LLC gathers it. Gas from oil wells: Oneok Midland Midstream, LLC buys it; Enlink Permian, LLC gathers it. The buyer's price is what a royalty check is figured on.

How many 1099s should an owner expect for 2025?
Two companies filed this lease's reports behind 2025 checks: Endeavor Energy Resources L.P. and Diamondback E&P LLC. 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.

  • Good to know

    15 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.
