About this data

One row per API number from the RRC permit record, with the permit count, deepest permitted depth, and latest permit. The production flag and last reported month come from PDQ lease reports on the leases the well is completed on; volumes are not shown here because Texas reports them by lease, not by well. Rebuilt after each daily permit load.

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