How to read this page
The arithmetic is one multiplication per stream per month. Here it is, worked, on a real row from the table above.
May 2026 — as filed, then multipliedworked
Condensate 700 bbl × $106.41 = $74,487 Gas 10,817 Mcf × $ 3.05 = $32,947 ──────────────────────────────────────────────────── Month total $107,434
The volumes are the state's, unchanged
Every barrel and every Mcf on this page is a number the Railroad Commission of Texas published in its monthly production query. Nothing is modelled, estimated or filled in.
The dollars are a multiplication, not a valuation
Volume × a published monthly price. It is not what the operator was paid: it takes no account of a contract, a differential, a transportation deduction, or the share any one owner holds.
Oil and gas are priced differently
Oil is a Texas realisation — the crude oil first purchase price. Gas is a benchmark, because no free Texas wellhead gas series exists at any date. The prices page publishes the difference rather than correcting it away.
A lease is not a well
The state reports oil on lease and gas on well, and this page is the lease grain. 06/G/256414 is the state's own key, not one this site invented.
