Stirring Fluid Loss Manual
100031980 Revision F 7
1 Introduction
The Stirring Fluid Loss Assembly simulates filtration at downhole conditions in a
wellbore. This test instrument determines the volume of fluid loss (filtrate) from a
cement slurry, water-based mud or fracturing fluid at a set temperature and pressure.
The test results are used to evaluate the fluid-loss control properties.
By controlling the fluid loss during cementing operations, the cement job will be
more successful. Adding various chemicals to a cement slurry will minimize fluid
loss. If fluid is lost, then cement viscosity and hydration rate will increase and
circulation rate will decrease.
The advantage of this instrument is that slurry preconditioning and testing are
performed in the same cell, eliminating the need to cool or transfer hot test slurry,
possibly changing the properties of the test slurry.
The Stirring Fluid Loss Assembly is designed for conformance with relevant
standards and practices as published by API Subcommittee 10 on Well Cements.
