  • Fluid Loss in cement slurries for oil well applications

    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.
