Abstract
The impact of CO2 on global warming has become a reality and major CO2 producers must take steps to address a 40% increase in concentration that has occurred globally since the early 1800’s. This study looked at the relationship between supercritical CO2 and sandstone reservoirs in the Illinois Basin. Specifically the Mt. Simon and St. Peter sandstone were studied and their characteristics were compared to data collected in the Tough-React model (Xu) response for a normalized sandstone. The data compared showed that with an increase in depth, the ion concentration increases allowing for more secondary mineralization to occur along with the formation of clays. Major minerals are present in both the Mt. Simon and St. Peter that raise concerns for sequestering CO2.
