From: An experimental study on the rate and mechanism of capillary rise in sandstone
Photographs of the three types of capillary rise experiments. a Experiment using a dried core without a lateral seal. b Experiment using a core with a lateral seal. Capillary rise was initiated after water in pores with a radius >10, >3, >1, or >0.36 μm was expelled. c Experiment for evaluating the height profile of water saturation. Left: during capillary rise; right: after samples are cut
