About this data

One row per API number: every well on the Railroad Commission wellbore schedule, and every API number a drilling permit names. Operator, field, status, and dates are the schedule's where it lists the well, the latest permit's otherwise. Permits on file counts every permit and amendment. Texas reports production by lease, so a well shows the last month its lease reported and no volumes. Nothing is estimated.

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