Capillary Suction Time Test
Capillary Suction Time Test :
(n.) Drilling Fluids. A type of static filtration test for water-base drilling fluid that measures the filtration rate (time for free water to pass between two electrodes) using filter paper as the medium. It is used primarily to indicate filter-cake permeability, but data from the test have been used to study how clays and shales react in filter cakes and how brines of various types affect clays in a filter cake. Alt. form: capillary-suction-time test
