Cement slurry fluid-loss-control additives (FLAs) -

2015-6-25  Factors affecting the use of fluid-loss-control additives (FLA) Neat cement slurries normally exhibit an uncontrolled API fluid loss of at least 1,500 cm 3 /30 min. This value is excessive for most cementing operations, where permeable formations are encountered or where long columns of cement

Fluid Loss in cement slurries for oil well applications

2021-1-23  Hence, for a cement slurry you plan to use for example inside a casing, fluid loss is not a relevant factor in the design. Now, fluid loss property of a cement slurry is also connected to free water and stability of the slurry, so for a useful cement slurry even inside casing, good fluid loss (normally, meaning low) is indirectly a factor.

Fluid Loss Control - an overview ScienceDirect Topics

Fluid loss control additives are employed for maintaining a constant water/solid ratio in cement slurries downhole by controlling the rate of water loss to adjacent permeable zones through suitable viscosification; otherwise the cement slurries would lose water by filtration into these zones. This filter loss may be static or dynamic.
