The database is searchable by county, township, operator, well status and type. Searches return results of 50 per page that include basic well information only. IDNR indicates hyperlinks should be available to view additional information and documents for individual wells, but that functionality is not working as of 1/1/2020. The full results of a search are downloadable in CSV format, however.
