Energy Resour. Technol. 2014;136(4):042908-042908-5. doi:10.1115/1.4027566 Figure Legend: CT images of 1 in. × 12 in. cement–sandstone composite cores. The brighter half is the cement while the darker half is the sandstone. Longitudinal and cross sectional views of the image reveal effective bonding between the cement and the rock before and after core flooding. White arrows show where cross section was taken from: (a) 0% mud contaminated core before core flood; (b) 10% mud contaminated core before core flood; L: Longitudinal view of composite core, C: Cross section of composite core.
