Initial results show Mt. Simon Sandstone in Macon County is suited to carbon storage
Preliminary results from a stratigraphic characterization well drilled in December 2018 by the Illinois State Geological Survey (ISGS) and collaborators near Mt. Auburn, Illinois, indicate that the Mt. Simon Sandstone at this location has excellent reservoir characteristics for storage of CO2. The T. R. McMillen #2 well is part of the CarbonSAFE Illinois–Macon County project, which is intended to establish the feasibility of storage of 50 million tonnes or more of CO2.
