Oil and Gas Well Data and Maps

Every producing state publishes its own well records, and no two agencies organize them the same way. These posts explain where each state keeps its wells, permits, logs and production, how to read what you find there, and where the official tools stop.

Start with the API well number, the one identifier that follows a well across every agency system, and with how surface and bottomhole locations differ. From there the guides cover orphaned and abandoned wells, injection and disposal wells, royalty paperwork such as division orders, and the gas composition and heating value data that tie a well to what it produces. Wyoming and underground injection topics sit here until they have enough posts for hubs of their own.

Each guide is written against the agency's own tool, so it names the search fields that work, the records that system leaves out, and where the same well turns up in another database. Where the public data is thin, the posts say so rather than fill the gap.
