EAST KEYSTONE (SAN A HOLT UNIT)
Operated by FORMENTERA OPERATIONS LLC (P-5 276959) in the KEYSTONE (CONSOLIDATED) 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 38 leases and 425 wells, and the rule below applies to all of them.
A drilling unit in this field needs at least 10 acres. The field rule took effect on 2016-01-01.
The Commission's schedule remark for this field reads: “RULE.”
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 | 268,888 bbl | $14,856,307 |
| Casinghead gas | Production | 108,772 Mcf | $323,400 |
| Total | $15,179,707 | ||
Wells on this lease (76)
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 31.9390, -103.0016. A lease has no coordinate of its own — that point is the mean of its wells, and they span 2.1 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, 76 of 76 wells. Median 5,327 ft, with the middle half between 5,200 and 5,500 ft; the shallowest is 4,727 ft and the deepest 10,280 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, 76 of 76 wells, May 1974 – Sep 2025. 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 26.6 years across the 15 wells that filed both dates, with the middle half between 24.2 years and 42.5 years. A further 3 wells are excluded, because the last completion the Commission holds for them is dated after the plug date. Both dates are the latest of their kind on the wellbore record and they are filed separately, so the two need not run in order. The gap is the distance between two filed dates — it is not a statement of how long the well produced.

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 565 bbl × $106.41 = $60,122 Casinghead gas 3 Mcf × $ 3.05 = $9 ──────────────────────────────────────────────────── Month total $60,131
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/46985 is the state's own key, not one this site invented.
