Queryable CSV
One row per lease with the first and last production cycle it ever reported.

Free. You will be asked to confirm an email address before the files are built — that is the only gate, and it is there so we can tell you when a large export is ready.
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.
1.1 million leases with the earliest and latest production cycle recorded for each. It is the index you want before touching the 76 million row cycle table.
What you can do with it
Find leases that started producing in a given month, leases that have stopped, and the productive life of any lease — without scanning the full production history.
Gotchas
The min and max cycles are stored as integers in YYYYMM form, so 202601 is January 2026 and arithmetic on them is not date arithmetic.
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.

key
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. | — |
| 4 |
operator_no
join
|
text | — | The operator's six-digit RRC P-5 organization number. Join to the P-5 Organization dataset for the company's name, address and P-5 status. | — |

field_no

lease_name

text | — | Lease name as filed. | — |

operator_name

field_name

text | — | Field name. | — |
| 12 |
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

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 Lease Summary (master) joins to PDQ Lease Production by Cycle on Oil gas code and District number and Lease number — one row here matches many rows there.
summarises the monthly production
The summary gives a lease's first and last production cycle; the cycle table gives every month in between. Read the summary first if you are about to scan 76 million rows.
pdq-lease-summary.oil_gas_code = pdq-lease-cycle.oil_gas_code AND pdq-lease-summary.district_no = pdq-lease-cycle.district_no AND pdq-lease-summary.lease_no = pdq-lease-cycle.lease_no
