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.
A chemical additive used to control the loss of fluid to the formation through filtration. In cementing operations, loss of the aqueous phase can severely affect the performance of the slurry and set cement. In almost any operation, loss of fluid to the reservoir formation carries a
The measured amount, multiplied by 2, is the fluid loss of that particular cement slurry. This is the standard way of measuring static fluid loss. In some cases, the slurry will leak off all the fluid before the 30 minutes and then just blow air through.

In Petroleum Engineer's Guide to Oil Field Chemicals and Fluids (Second Edition), 2015. 2.1.4 Testing of fluid loss additives. Fluid loss prevention is a key performance attribute of drilling fluids. For water-based drilling fluids, significant loss of water or fluid from the drilling fluid into the formation can cause irreversible change in the drilling fluid properties, such as density and
Loss of fluid from a slurry design, can have serious effects on many key slurry parameters and cement placement. When a fluid loss additive is included in a cement slurry design, it will help maintain desired characteristics and properties such as rheology, thickening time, density and compressive strength.

A well bore cementing composition and method are shown in which a hydraulic cement, water and a non-retarding fluid loss additive are combined to form a cementing slurry. The non-retarding fluid loss additive is a copolymer of a first non-ionic water soluble monomer which resists hydrolyzing in a cement slurry and a second anionic monomer.
Fluid Loss Control Additives. As cement is pumped across a permeable rock surface under pressure, cement filtrate, or water is lost or squeezed out of the cement into the rock. Cement fluid loss must be controlled to obtain the right rheological properties for placing the cement and to ensure a good cement bond to pipe and formation.
The fluid loss additives, which are one of the three main additives on the oil cement slurry, can effectively reduce the fluid loss of oil cement slurry in the field condition and can also increase the viscosity and improve the stability of oil cement slurry [1, 2].

Tianjin Kelioil Engineering Material and Technology Co., Ltd. is a national high-tech enterprise specializing in the mass production of oilfield cementing additives
Nov 06, 2016· Static fluid loss per se; Static fluid loss happens while the slurry is liquid once it starts setting (> 30BC) filtration is quickly reduced until it stops. For deep wells, more than 5000 meters, a lower FL control could be required to ensure cement slurry stability at bottom hole conditions (FL additive provides viscosity and prevent
BASF’s state-of-the-art cement dispersants improve the slurry rheology such that long range pumping is greatly improved and at the same time water-reduced cement slurries are possible. Fluid loss additives, which are stable against high temperatures and concentrated salt solutions, ensure a reliable cementing job under difficult conditions.

Gerke
A fluid-loss test determines the relative effectiveness of a cement slurry to retain its water phase or to lose a portion of its water phase as a filtrate to the formation. Insufficient fluid loss control can result in the cement slurry dehydrating and bridging off the annulus, preventing the slurry from being pumped to its final location and
