The petroleum industry uses the Capillary Suction Timer to characterize shales and to optimize the electrolyte concentration in drilling fluids for minimizing its effect on shale formations.

Therefore, the apparatus automatically determines the capillary suction time (CST), which is the time taken by the filtrate ring to extend from a 32 mm to a 45 mm diameter. The typical time to …

The capillary Suction Time has been used since the 1970s as a quick and reliable method for characterizing sludge filterability and conditionability. It is sludge filterability that predominantly …

The Model 441 Capillary Suction Timer (CST) consists of a digital timer, sample cell, and a specially selected filter paper composed of unidirectional fibers. Aqueous samples are placed …

The Capillary Suction Timer, Model 440 measures the filtration rate of free water in a fluid. The instrument contains a control cabinet that houses a timer and connects to the test head with …

2024年11月6日 · The Capillary Suction Timer (CST) principle was developed at the Water Pollution Research Laboratory in Stevenage, England, for studying the filterability of sewage …

The capillary suction time test was developed to study the filter-ability of sewage sludge and evaluate the effects of pre-treatment chemicals and process conditions of sewage treatment. It …

The test results show the inhibitive effects of various salts and their concentrations on the dispersion of shale. Results can be graphed as time versus fluid type. Capillary suction time is …

Fluid Sensitivity Screening by Capillary Suction Time (CST) and Roller Oven (RO) Analysis. Measures the relative flow capacity of a slurry of ground formation rock used to form an …

CST simulates the shear and chemical forces present in drilling and completions to measure the hydrating properties of shale. For this test, the mixing time and shale-solids content are held …
