The ringed dot is this lease's well, 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 Ruby

When is the check for July 2026 due?
July 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 Sep 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 July 2026, so the full 4.6% on oil applies.
Source: Texas Comptroller, approved severance tax exemptions.
Check the tax on your stub
Who buys the oil and gas?
Oil: Enterprise Crude Oil LLC 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.
