The Capillary Suction Time TestTubing measures the relative flow capacity of a slurry of ground formation rock used to form an artificial core and it is an indication of clay swelling.
A rock sample with dispersible or swelling clays would have a lower pseudo permeability and will have a longer CST time while the one without clay or other fine particles would have a shorter retention time.
