17,111 wells on file. Open this county on the map.
Production is reported to us by state regulators. New Mexico and New York report per wellbore. Texas and Kansas report per lease, so for those states a well-level figure is exact only where the lease has a single wellbore; otherwise it is the lease total divided across its wellbores. 9,787 of 17,111 wells here have production on file. Full methodology and sources.
Depth range is measured from the wells on file, not a regional average.
