Distribution and Production of Oil and Gas Wells by State
Release date: January 7, 2011 | Next Release Date: To be determined
Distribution tables of oil and gas wells by production rate for all wells, including marginal wells, are now available for most states for the years 1995 to 2009. Graphs displaying historical behavior of well production rate are also available. To download data for all states and all years, including years prior to 1995, in an Excel spreadsheet XLS (4,000 KB).

The quality and completeness of data is dependent on update lag times and the quality of individual state and commercial source databases. Undercounting of the number of wells occurs in states where data is sometimes not available at the well level but only at the lease level. States not listed below will be added later as data becomes available.

The Distribution of Oil and Gas Wells and Production Project was undertaken by the Energy Information Administration, DOE to provide a database for analyses assessing the impact of technological development on marginal gas wells. The database, called the U.S.PetroSystem, was established in the spring of 2000 for the creation, maintenance and sharing of data used in the study of domestic and worldwide oil and gas resources, reserves, production, productive capacity, and their associated technologies and economics.
