Fluid Loss - an overview | ScienceDirect Topics

API fluid loss values on neat cement slurries (where practically measurable) lie well above l000 mL. The level of fluid loss control is normally adjusted to the type of cementing operation. Values below 200 mL are usually preferred and sometimes may need to be ~ 50 mL or less.
