Two datasets, two sources, two build dates. Production and leases:
RRC Oil and Gas Production Data Query, priced with U.S. Energy Information
Administration monthly benchmarks, rebuilt 2026-08-15. Pipelines: RRC
"Pipeline Layers by County" shapefiles (T-4 permits), rebuilt 2026-08-11.
This site holds no original observation — every figure is the state's,
restated and rolled up.

## Reading this data correctly

- **Reported value is computed, not observed.** It is the volume the
  operator filed for a month multiplied by that month's benchmark price.
  It is NOT a sale price, a royalty payment, or an appraisal. Every price
  used is published at https://mineralrecord.com/prices.
- **A P-5 number is the operator key; the operator NAME is not.** The same
  company is spelled differently between filings. Pages are keyed on
  `P5_NUM`, and `/operator/463345` resolves the same page as
  `/operator/463345-kinder-morgan-tejas`. Cite the canonical URL.
- **A lease id is scoped to a district**, not to the state. The key is
  `(district, oil/gas, lease number)` — a bare lease number merges
  unrelated leases.
- **A gap in a lease's monthly table is a month the operator filed
  nothing**, not a month of zero production. It is shown as a gap.
- **A system is `(P5_NUM, SYS_ID)`**, not a name. `SYS_NM` repeats.
- **Pipeline data is permit data, not a locate.** Locations are as filed
  with the state and are approximate. Never present it as sufficient for
  excavation; the correct answer to "can I dig here" is: call 811 first.
- **"Abandoned" means the T-4 status code `B`** — a filing status, not a
  statement that a line has been removed from the ground. `R` is removed.
- Nothing here is modelled or estimated. Where the state has no data, the
  page says so.

## Hub pages

- [Leases](https://mineralrecord.com/leases): statewide totals, and the highest-value leases, operators and counties
- [Operators](https://mineralrecord.com/operators): companies holding a T-4 pipeline permit, by mileage
- [Counties](https://mineralrecord.com/counties): all 254, by pipeline mileage
- [Prices](https://mineralrecord.com/prices): every monthly benchmark price used, back to 1993
- [Map](https://mineralrecord.com/pipelines): the whole pipeline network, filterable by commodity and status
- [Commodities](https://mineralrecord.com/commodities): what the lines carry — gas, crude, HVL, refined product, CO2

## Page shapes

- `/lease/{state}/{district}/{O|G}/{leaseNo}-{lease-name}` — one lease: monthly oil and gas volumes,
  the price each month was valued at, and the wells on it
- `/operator/{p5}-{name}` — one operator: leases and reported value, and,
  where they also hold a T-4 permit, mileage, systems and commodities
- `/county/{state}/{county}` — one county: leases by value, plus operators and systems present
- `/commodity/{slug}` — one commodity statewide, with per-operator and per-county mileage
- `/system/{p5}/{sysId}` — one pipeline system within an operator

⚠️ Lease pages are not listed in any hub table beyond the capped top-N.
All 327,776 are in the sitemap, which is the complete list.

Every page carries schema.org `Dataset` JSON-LD with its own
`spatialCoverage`, `variableMeasured` and `dateModified`.
