Oil and gas wells by state
2,975,896 well records from 22 state agencies, plus the deeper Texas record. Every figure below is the state's own — nothing is estimated, and a state that files no operator or no coordinate shows a gap rather than a guess.
Deep records
Texas holds far more than a well register — leases, production, operators, permits, the survey grid and the county appraisal rolls.
| State | What the site holds |
|---|---|
| Texas | Wells, leases, monthly production, operators, permits, fields, the Original Land Survey grid and mineral ownership |
Wells by state
One page per wellbore, from each agency's own register, with its counties listed. The last three columns say what that agency files: a blank is a field the state does not publish, not a field we failed to read.

A dash under Production means the state publishes no well-grain series this site can join to a well — not that its wells produced nothing. Nebraska, for one, files production against a lease or unit rather than a well, and attaching a lease’s volume to a single well would invent a number nobody filed.
Every record here comes from a free state agency feed. Nothing on this site is bought. Where a state publishes two well layers — Pennsylvania files conventional and unconventional separately — both are included and the page says which one a well came from.
