The Midwest Geological Sequestration Consortium (MGSC) has begun injecting CO2 for the first 1 Mt demonstration of carbon sequestration in the U.S. The CO2 will be stored permanently in the Mt. Simon Sandstone more than a 2km beneath the Illinois surface at Decatur.
MGSC is one of seven regional partnerships created by the DOE to advance technologies nationwide for capturing and permanently storing greenhouse gases that contribute to global climate change.
The CO2 is being captured from the fermentation process used to produce ethanol at Archer Daniels Midland Company’s (ADM) corn processing complex.
Schlumberger Carbon Services is providing full project management for the design and construction of all wells associated with the storage and deep monitoring parts of the project. Drilling of the injection well in 2009 confirmed suitability of the site and was followed by a seismic survey, a geophysical monitoring well, and a pressure and fluid sampling (verification) well, all in 2010. Completion of the verification well was followed by two rounds of initial fluid sampling to thoroughly document pre-injection reservoir conditions.
