Well logs are the ones loaded into Petrora from the regulators' log indexes, so far for Texas, with more states and data sources to follow. A log's kind is the regulator's description of it; a digital log is a LAS file of curves. Each well's page lists its logs and links to the regulator for the files.

About this data

One row per API number from each state regulator's records, in one shared shape. Status and type are shown in the regulator's own words; the filters use one vocabulary. A well is tied to a formation through the field or pool it is completed in. Volumes appear where a state reports production by well, summed over the twelve months ending in that state's last reported month. Nothing is estimated.

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