Sources and disclaimer

Well locations come from the oil and gas regulator of each of the 12 states. The Oil and Gas Infrastructure Mapping (OGIM) database by Environmental Defense Fund and MethaneSAT seeded the site and still supplies Texas well names and operators. Each well record shows which source it came from.

Disclaimer: locations are approximate, may be out of date, and are not a survey. The regulator's own record is authoritative. Don't rely on this site for legal, safety or drilling decisions.
