About this data

Lease summaries from the RRC PDQ production dump: lifetime oil, gas, and casinghead, well count from completion reports, and the first and last month with a report. Lease reports leave the county blank; the county shown is the one the lease's completed wells are in, rebuilt nightly.

Developers: this page as JSON is GET /v1/data/leases/tx, documented in the API reference.
