API Fluid Loss Test
API Fluid Loss Test :
(n.) Drilling Fluids. A test to measure static filtration behavior of water mud at ambient (room) temperature and 100-psi differential pressure, usually performed according to specifications set by API, using a static filter press. The filter medium is filter paper with 7.1 sq. in. filtering area. A half-size cell is sometimes used, in which case the filtrate volume is doubled. Syn: API fluid-loss test. Ant: High-Pressure, High-Temperature Filtration Test.
