Micro-computed tomography tiff stacks of a Mt. Simon core at residual conditions. The core is from a depth of 6,926 ft, the sub-sample tested is 0.25 inch diameter by 1 inch length. This data was used to complete contact angle measurements and analyze the influence of clay-rich regions in the pore space on residual trapping efficiency.

The sample porous medium is from Mt. Simon sandstone at a depth of 6700 feet. The formation is located at verification well number 2 of a study site in Decatur, Illinois where Illinois State Geological Survey carried out a pilot injection study to better understand the feasibility of full-scale carbon capture and storage (Finley, 2014). A core plug from the formation was scanned by micro-CT imaging technique at the National Energy Technology Laboratory (NETL) of...
