The Production of Oil and Gas in Ohio (POGO) database, the most comprehensive oil and gas database ever assembled for Ohio, contains production data gathered directly from petroleum industry companies and individuals plus all of the production data gathered by the Division of Oil and Gas since 1983. All records in this data set have been matched against valid permits (or older well records). The POGO database contains over 1,300,000 yearly records for more than 83,000 wells. The yearly records include some data as old as 1921. The database also contains roughly 84,000 monthly production records. Standardized queries have been provided for the user as part of the Microsoft Access database application, including the ability to search by county, township, section, lot, producing formation, operator, API number, and various combinations of these attributes. User-defined queries also can be constructed. Decline curves and estimated ultimate recovery (EUR) calculations can be produced and printed on a well-by-well basis. Query results can be exported to Microsoft Excel for use with other software packages.
