The datasets contain high resolution X-ray micro-tomographic images (raw, filtered and segmented) obtained after a drainage-imbibition cycle in a water-wet Ketton carbonate rock sample. Two subsets (SSa and SSb) were extracted from the tomographic images on which we have performed automatic effective contact angle measurements. Further details for image analysis can be obtained from: 1. Singh, K., Bijeljic, B. and Blunt, M.J. (2016).
