MAMMOTH B
Operated by WILDFIRE ENERGY OPERATING LLC (P-5 923444) in the AGUILA VADO (EAGLEFORD) field. Every figure below is a volume the Railroad Commission published, multiplied by a monthly price you can check.
What this lease produced, and what it was worth
Oil and condensate are valued on the volume the state records as disposed of; gas and casinghead gas on the volume produced. They are different columns of different files, and the difference is not cosmetic.
| Stream | Basis | Volume | Value |
|---|---|---|---|
| Oil | Disposition | 536,018 bbl | $43,862,659 |
| Casinghead gas | Production | 264,706 Mcf | $1,184,111 |
| Total | $45,046,770 | ||

Volume × price = value, one row per cycle. The price columns are the same series published on the prices page — nothing here is modelled.

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.
Oil 4,490 bbl × $106.41 = $477,781 Casinghead gas 2,675 Mcf × $ 3.05 = $8,148 ──────────────────────────────────────────────────── Month total $485,929
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. 05/O/4442 is the state's own key, not one this site invented.
