The BROOKELAND (AUSTIN CHALK, 8800) field

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 488 leases and 597 wells, and the rule below applies to all of them.

A drilling unit in this field needs at least 160 acres. The field rule took effect on 2009-10-22.

The Commission's schedule remark for this field reads: “ACRES. DOCKET EFFECTIVE 10-22-09.”

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
Condensate	Disposition	56,408 bbl	$1,903,370
Gas	Production	1,013,373 Mcf	$4,168,255
Total			$6,071,626

Every month this lease reported (167)

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.

Jul 2011 — as filed, then multipliedworked

Condensate           171 bbl  × $ 94.14 =    $16,098
Gas                    0 Mcf  × $  4.52 =         $0

────────────────────────────────────────────────────
Month total                                  $16,098

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/167871 is the state's own key, not one this site invented.
