Micro-CT imaging of capillary plate experiments on water-wet and mixed-wet heterogeneous sandstones

Description

The dataset contains micro-CT images for quasi-static oil- and waterflooding experiments performed on two sister heterogeneous sandstone samples, where one sample (20 mm in length and 6 mm in diameter) was water-wet, and another (13 mm in length and 6 mm in diameter) was chemically treated to be mixed-wet by immersing the sample in 25 ml of decane with 5 wt.% octadecyltrichlorosilane (OTS) and sonicating it in an ultrasonic bath for 5 minutes. After 24 hours, the sample was removed from the solution, followed by cleaning with isopropanol and drying. Scans were obtained using Environmental Micro-CT (EMCT) scanner at Ghent University’s Centre for X-ray Tomography (UGCT).
