Table 6.

Summary of conducted CT scans for both, the imbibition-drainage and the ${CO}_{2}$ test. Each CT scan was complemented by low-frequency and ultrasonic velocity measurements. The ‘attempted’ column, annotated with numbers in brackets, represents the target saturation levels from the test protocol. The ‘measured’ column displays the actual saturation levels of the samples, determined after the CT scans.
