Drilling begins in Illinois CO2 storage test
Storage, Feb 20 2009 (Carbon Capture Journal)
- The Midwest Geological Sequestration Consortium (MGSC) has begun drilling the injection well for their large-scale CO2 injection test in Decatur, Illinois.
The project will capture CO2 from the Archer Daniels Midland (ADM) ethanol production facility in Decatur and inject it in a deep saline formation more than a mile underground.
Starting in early 2010, up to one million metric tonnes of CO2 from the ADM ethanol facility will be compressed and injected in the Mt. Simon Sandstone formation, at a depth between 6,000 and 7,000 feet, over a three-year period.
In January 2009, ADM — in collaboration with the Illinois State Geologic Survey at the University of Illinois, which leads the MGSC — was issued an Underground Injection Control permit by the Illinois Environmental Protection Agency for the injection well.
Obtaining the permit is significant because it allows the consortium to proceed with drilling, making the MGSC the first DOE Regional Partnership to begin drilling a development phase injection well. The drilling is expected to take about 2 months to complete.
Following injection, a comprehensive monitoring program will be implemented to ensure that the injected CO2 is safely and permanently stored. The position of the underground CO2 plume will be tracked, and deep subsurface, groundwater, and surface monitoring around the injection site will be conducted. The monitoring program will be evaluated yearly and modified as needed.
