Imbibition in carbonate rocks: high-resolution time-resolved synchrotron X-ray micro-tomography

This movie shows a secondary imbibition process in which the wetting phase (brine) displaces the non-wetting phase (oil) in a carbonate rock sample (4 mm diameter) at reservoir pressure conditions. The brine and rock phases are not shown for effective visualization. The time-resolved tomographic images were acquired at Diamond Light Source, U.K. (Beamline I-13), with a voxel size of 3.28 µm and a time-step of 38 s.
