New geologic data for central Illinois

[October 10, 2012]
CHAMPAIGN -- The Illinois State
Geological Survey, a division of the Prairie Research Institute,
will release new seismic reflection data Wednesday for a continuous
120-mile east-west line from Meredosia to southwestern Champaign
County (see
map). It is the only seismic line known to have been collected
in that region of Illinois. Like ultrasound medical imaging, seismic
reflection uses sound waves to produce its images, but of rocks and
sediments in the earth's subsurface.

"This is higher quality technical data than we have ever had for
this part of Illinois," said Don McKay, director of the ISGS. "It
was funded with federal stimulus money, and we are releasing it now
to the private sector because of its potential value for energy
development." The seismic reflection survey is part of a U.S.
Department of Energy-sponsored research project and was originally
acquired to help evaluate the suitability of rocks in central
Illinois for large-scale storage of carbon dioxide produced by
electric generating plants and industrial processes such as biofuel
production. However, the seismic reflection data also can be used in
the exploration for oil and gas.
The seismic data were collected for the ISGS by WesternGeco, a
division of Schlumberger Limited, in order to characterize the
properties and thicknesses of sedimentary rocks that overlie
granitic basement.
The research project was funded by the U.S. Department of
Energy's National Energy Technology Laboratory and the Illinois
Department of Commerce and Economic Opportunity's Office of Coal
Development, through the Illinois Clean Coal Institute.
The ISGS will discuss and distribute the data Wednesday at the
headquarters of the Illinois Oil and Gas Association in Mount Vernon
to those preregistered. People unable to attend the event may
request the data online at

The Prairie Research Institute at the University of Illinois at
Urbana-Champaign is the home of the Illinois Natural History Survey,
Illinois State Archaeological Survey, Illinois State Geological
Survey, Illinois State Water Survey and Illinois Sustainable
Technology Center. The institute is a unique source of research,
expertise and data, providing a sound basis for independent
scientific analysis and decision-making. It was established by state
statute in 2008 to bring together these century-old institutions and
to sustain and expand their basic and applied research and service
roles. Prairie Research Institute scientists apply cutting-edge
science to grow the economy, promote public health and safety, and
steward the vast resources of Illinois. For more information, visit
