O'BRIEN A
Operated by ROFF OPERATING COMPANY, LLC (P-5 724620) in the BREEDLOVE (SPRABERRY) field. Every figure below is a volume the Railroad Commission published, multiplied by a monthly price you can check.
The Railroad Commission's own record for the field this lease produces from, including the spacing rule that governs how close together its wells may be drilled.
These are facts about the field, not about this lease. The field holds 37 leases and 62 wells, and the rule below applies to all of them.
A drilling unit in this field needs at least 80 acres.
The register flags this field for hydrogen sulphide. That is a poisonous gas that occurs naturally in some formations. The flag is a property of the field as the Commission records it. It is not a measurement taken at this lease, and it is not a statement that gas is escaping anywhere.
The Commission's schedule remark for this field reads: “OP. 80 ACRE DIAG. 3250”
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 | 20,507 bbl | $1,435,738 |
| Casinghead gas | Production | 32,302 Mcf | $212,937 |
| Total | $1,648,675 | ||
Every month this lease reported (76)
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 360 bbl × $105.96 = $38,146 Casinghead gas 8 Mcf × $ 4.33 = $35 ──────────────────────────────────────────────────── Month total $38,180
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. 08/O/37571 is the state's own key, not one this site invented.
