What this is
One of the sixteen delimited tables inside the monthly Production Data Query dump. RRC publishes the dump as a single archive; EZRRC publishes each table inside it separately so you can take the one you need instead of a 3.6 GB zip.
547,000 leases. This is the table that makes production data legible: it maps the oil/gas code, district and lease number key to the lease name, the operating company, the field and the well number, and flags leases that are off schedule or severed.
What you can do with it
Turn a lease key into a name, a field and an operator.
Find every lease an operator holds, and find leases that have been severed — the Commission's enforcement action for delinquent filings.
Gotchas
The severance flag means the lease has been severed for a compliance failure and cannot legally sell product. It is one of the most consequential columns in the catalog and it is a single character.
A lease number is only unique with the oil/gas code and the district in it. Oil lease 027587 in District 08 and gas lease 027587 in District 08 are different leases; so is oil lease 027587 in District 09.

join
|
text | — | RRC's INTERNAL district number, 01 to 14 plus 20 for statewide. This is not the district name the industry uses: internal 07 is District 6E, 08 is 7B, 09 is 7C, 10 is District 08, 11 is 8A, 13 is 09 and 14 is District 10. Join to the district directory rather than reading it as a label. | RRC district (internal number) |

lease_no
key
join
|
text | — | RRC lease number. Unique only within a district and a schedule, so a lease key is district + oil/gas code + lease number. | — |

|
text | — | Flag noting if a P-4 Severance was issued and is in effect. | — |
| 13 |
ingested_at
|
timestamptz | — | When the upstream pipeline last wrote this row. Not an RRC field — it is EZRRC's provenance stamp, and it is what the freshness badge is measured against. | — |
Code lookups used here
Every coded column in this dataset resolves to a real lookup table, so
a well code of G can be read as what it actually means.
RRC district (internal number) 14 values
Read by district_no
RRC's internal sequential district numbering, 01 to 14 plus 20 for statewide. The production data, the UIC database and the high-cost gas certifications all use this. Internal 07 is District 6E, 08 is 7B, 09 is 7C, 10 is District 08, 11 is 8A, 13 is 09 and 14 is District 10. There is no internal 12.

Oil or gas schedule 2 values
Read by oil_gas_code
Which schedule a lease is carried on. This is not decoration: an oil lease number and a gas lease number can be the same digits and mean different leases, so a lease key is only unique with this code and the district in it.
| Code | Means |
|---|---|
O |
Oil Carried on the oil proration schedule; lease numbers are oil lease numbers. |
G |
Gas Carried on the gas proration schedule; lease numbers are gas well IDs. |

What this joins to
The Railroad Commission never states these keys anywhere in the files. They are the reason the data is hard to use, so here they are with the exact columns on both sides.
PDQ Regulatory Lease Directory joins to PDQ Well Completion Directory on Oil gas code and District number and Lease number — one row here matches many rows there.
is produced by the wells
The wells that make up a lease. Texas reports oil production by lease, so this is as close as the production data gets to a well — it tells you which wells are on the lease, not what each one made.
pdq-regulatory-lease-directory.oil_gas_code = pdq-well-completion.oil_gas_code AND pdq-regulatory-lease-directory.district_no = pdq-well-completion.district_no AND pdq-regulatory-lease-directory.lease_no = pdq-well-completion.lease_no
PDQ Regulatory Lease Directory joins to PDQ Lease Production by Cycle on Oil gas code and District number and Lease number — one row here matches many rows there.
produced from the lease
Production rows carry a lease key and nothing else identifying. The regulatory lease directory is what turns that key into a lease name, an operator, a field number and a well number, and it is where the severance flag lives. Exact on all 5,000 sampled rows. The key is three columns, not one: the oil/gas code, the district and the lease number. Any two of them alone are ambiguous.
pdq-lease-cycle.oil_gas_code = pdq-regulatory-lease-directory.oil_gas_code AND pdq-lease-cycle.district_no = pdq-regulatory-lease-directory.district_no AND pdq-lease-cycle.lease_no = pdq-regulatory-lease-directory.lease_no
PDQ Regulatory Lease Directory joins to High Cost Gas on District number = District and Lease number = Lease number — one row here matches many rows there.
certifies the lease
The certification file and the production system agree on the district (both use the internal numbering) and on the zero-padded lease number, so those two columns join exactly — 4,998 of 5,000 sampled certifications find their lease. They do not agree on the oil/gas code: the certification file writes 'GAS' and the production system writes 'G', which is why that column is not part of the join. Every row here is gas. This is also the route to the field: the certification carries no field number, but the lease directory it lands on does.
high-cost-gas.district = pdq-regulatory-lease-directory.district_no AND high-cost-gas.lease_number = pdq-regulatory-lease-directory.lease_no
PDQ Regulatory Lease Directory joins to PDQ Lease Disposition by Cycle on Oil gas code and District number and Lease number — one row here matches many rows there.
disposed of production from the lease
The lease key resolved to a name, operator and field.
pdq-lease-disposition-cycle.oil_gas_code = pdq-regulatory-lease-directory.oil_gas_code AND pdq-lease-disposition-cycle.district_no = pdq-regulatory-lease-directory.district_no AND pdq-lease-disposition-cycle.lease_no = pdq-regulatory-lease-directory.lease_no
PDQ Regulatory Lease Directory joins to PDQ Onshore Lease Summary on Oil gas code and District number and Lease number — one row here matches many rows there.
summarises the lease
The onshore lease summary's key, resolved to the lease directory.
pdq-onshore-lease-summary.oil_gas_code = pdq-regulatory-lease-directory.oil_gas_code AND pdq-onshore-lease-summary.district_no = pdq-regulatory-lease-directory.district_no AND pdq-onshore-lease-summary.lease_no = pdq-regulatory-lease-directory.lease_no
