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.
