ISGS to Release Seismic Reflection Survey Across Central Illinois

Map of 120-mile long seismic reflection survey across central Illinois

The Illinois State Geological Survey (ISGS), a division of the Prairie Research Institute at the University of Illinois Urbana-Champaign, recently acquired a new 120-mile long seismic reflection survey across central Illinois as part of a U.S. Department of Energy (U.S. DOE) sponsored research project to characterize reservoir rocks for geologic sequestration of carbon dioxide. The continuous east-west line extends from Meredosia to southwestern Champaign County (see accompanying map) and is the only seismic line known to have been collected in that region of Illinois.

These seismic data were collected and processed for the ISGS by WesternGeco, a division of Schlumberger, in order to characterize the properties and thicknesses of sedimentary rocks that overlie granitic basement. These data were originally acquired to evaluate areas suitable for large-scale sequestration (storage) of carbon dioxide produced by electric generating plants and industrial processes such as biofuel production. However, the seismic reflection data is also suitable for the exploration of oil and gas.

Because these data may provide a strong basis for petroleum exploration, the data will be released at a pre-announced time and place to all interested parties. The ISGS will discuss and distribute the data at 2:00 PM on October 10, 2012, at the headquarters of the Illinois Oil and Gas Association, 824 Illinois Highway 15 East, Mount Vernon, Illinois 62864. Persons present will receive a USB drive containing PDF-format copies of the seismic data as well as SEGY formatted data at no charge. Registration will be required via the ISGS website so that the number of copies of the data can be estimated. Data recipients will be required to sign a release of liability in order to receive the data. Persons unable to attend the data release event may request the data via the ISGS website at Such requests will be filled by either online downloading or via USPS mailings.
