St. Peter Sandstone, Illinois Basin

Comments on Geologic Parameters

13 Rock/Water Reaction:

The St. Peter Sandstone is a mature quartz arenite that contains little or no silt and clay, except near its perimeter. Therefore, we conclude that the potential for rock/water reaction with high CO2 brine is low.
