PRESTON, SAM R.
Operated by PARKER & PARSLEY DEVELOPMENT CO. (P-5 640889) in the SPRABERRY(TREND AREA DEAN-WLFCP) 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 | 10,037 bbl | $175,258 |
| Casinghead gas | Production | 22,865 Mcf | $0 |
| Total | $175,258 | ||
22,865 Mcf of this lease's gas, across 2 months, carries no value here. No free Texas wellhead gas price exists before 1997, so those months are left out of the total rather than valued at zero. The total above is therefore a floor, not an estimate.
Wells on this lease (14)
Every wellbore the Railroad Commission records against this lease key, with the depth, the last completion and the plug date exactly as filed. A well with no plug date is not stated to be producing — the state files no such flag.
These wells centre on 31.7137, -101.8285. A lease has no coordinate of its own — that point is the mean of its wells, and they span 1.7 miles.
What these wells add up to
Every figure below is counted over all of this lease's wells, not over the rows listed above. The Railroad Commission files two facts about a well's state — a plug date and a proration-schedule flag — and a well can carry both, so they are published as separate counts and never merged into a status.
What the state filed about each well
A plug date is the date the Commission recorded the wellbore as sealed with cement and abandoned. It is the only end-of-life fact Texas files. There is no "active" flag on a well, so this page does not print one — a well with no plug date is not stated to be producing.
How deep they were drilled
Total depth in feet, 14 of 14 wells. Median 9,200 ft, with the middle half between 9,100 and 9,425 ft; the shallowest is 9,000 ft and the deepest 12,503 ft. The median is published rather than the mean, because a single mis-keyed depth moves a mean and cannot move a median.
When they were last completed
Last completion by decade, 13 of 14 wells, Oct 1985 – Oct 2019. This is the LAST completion filed on each wellbore, not the first — a well recompleted in 2019 counts once, in the 2010s.
Last completion to plug: a median of 17.5 years across the 13 wells that filed both dates, with the middle half between 2.3 years and 30.6 years. The gap is the distance between two filed dates. It is not a statement of how long the well produced.

The API number is the state's, prefixed 42 for Texas. A well is matched to this lease by the lease key the Commission files on the wellbore record, so a well that has moved between leases appears under each one it was filed against.

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 5,496 bbl × $ 17.90 = $98,378 Casinghead gas 11,298 Mcf × no price — ──────────────────────────────────────────────────── Month total $98,378
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/20120 is the state's own key, not one this site invented.
