Essential to successful geological sequestration of CO2 are sufficient sink capacity, adequate injection rate, integrity of the storage reservoir, and verification of safe, long-term storage. The development of the Illinois Basin – Decatur deep saline sequestration project is used to illustrate the workflow necessary for site selection, well design, permitting, and monitoring and verification of the injected CO2.

The Midwest Geological Sequestration Consortium (MGSC), Archer Daniels Midland Company (ADM), and Schlumberger Carbon Services collaborated to drill a 7,230 ft well and will inject and permanently store CO2 from the ADM ethanol plant at Decatur, Illinois. The Illinois Basin - Decatur project will inject one million metric tonnes of CO2 over a three year period into the Mt. Simon Sandstone. Numerous monitoring and verification methods are being used to evaluate the potential of carbon sequestration in the Illinois Basin. The target reservoir is the Cambrian Mt. Simon Sandstone, a thick sandstone reservoir with an overlying shale seal.

Regional, as well as local, geologic and geophysical characterization of the target reservoir is necessary for successful completion of a sequestration project. Because there are no penetrations into the Mt. Simon Sandstone within a 17-mile radius of the Decatur site, regional geology and more distant wells were used as a proxy for actual well data. Prior to drilling, seismic reflection data were used to help characterize the subsurface geology and to estimate drilling depths. Later, 3D reflection seismic and vertical seismic profiles will be used to monitor and verify the location of the injected CO2.

The environmental monitoring program began in spring 2008 and will continue throughout the project. The injection well to the Precambrian granite basement was drilled and cased in February-May-2009. Injection of CO2 will begin in early 2011 and will continue through 2013, followed by two additional years of monitoring.
