For effective geological sequestration of CO_2, it is critical to understand the processes associated with CO_2 movement and trapping in reservoirs, which requires a proper understanding of a diverse set of heterogeneous geologic properties. A highly-resolved data set from the Cambrian lower Mt. Simon sandstone reservoir (Unit A) in Decatur, Illinois, was used in a new approach to analyzing the variance of permeability and porosity. Newly interpreted bedding types, along with other factors, including grain size, and presence of bleached alterations, were considered in the analysis of variance. The results reveal that the factors contributing most to the sample variance …
