The Petroleum Database Management System (PDMS) is a web application designed to distribute petroleum-related information from the Indiana Geological Survey (IGS). The database contains information on more than 70,000 petroleum-related wells drilled in Indiana. The data include information on well locations, completion zones, logs, operators, lease names, tests, hydrocarbon shows, samples, cores, geologic formations and tops, and much more. The PDMS is built around three modules: 1) the Well Record Tables; 2) the Map Viewer, which together with the Well Record Tables, provide two interfaces for viewing petroleum well information; and 3) the Fields and Production summaries, which summarize oil, gas, and gas storage fields, and historical oil production.
Well Record Tables
Well data are displayed in tables. Viewing and downloading well records is only possible in the Well Record Tables. The well data are organized in outline form where each well is identified by the IGS ID, a unique number that represents a unique location on the ground. The IGS ID provides the link between the Well Record Tables and the Map Viewer. Each well is subdivided in to a series of "events" that make up the well's history. Data for each well event are contained in subtables that are linked to that event.
The Map Viewer is an interface that displays interactive maps of petroleum well data. This map viewer is connected to the Well Record Tables when detailed information is needed.
Fields and Production
Summary information on oil, gas, and gas storage fields can be searched for by field name. Field production histories for oil fields are shown in tables and graphs.
Thanks to Indiana Oil and Gas Association
The Indiana Geological Survey appreciates a generous grant given by the Indiana Oil and Gas Association (InOGA) in 2009 in support of the Indiana Geological Survey's effort to scan the petroleum well records and to make them available online. InOGA's contribution funded the scanning and integration of all logs and documents of the Indiana "Type Log Wells," 356 wells which were selected by John B. Droste as the most geologically informative wells in Indiana based on their distribution, total depth, available geophysical log suites, and associated sample and core information where possible. The wells that make up this set are distributed around the state with an average of four wells per county. In most cases these constitute the deepest wells in the state and are often ones that have been used in other survey investigations and publications. A complete listing of these 356 wells can be obtained by checking the "Type Log Wells" box in the "Additional Search Options" portion on the "Well Search Menu" when using the Well Record Tables function on the PDMS home page. The wells are also shown in the Map Viewer by selecting the "Type Log Wells" option listed in the "Special Wells Section" of the Layers Menu.
