Fluid Loss Additives - Halliburton
A fluid-loss additive made from synthetic polymer technology which is compatible with salt, seawater, and CaCl2 and effective up to 350°F (176.7°C) without over-retarding at temperatures as low as 80°F (26.7°C); it is not a strong dispersant so it can be used in normal and heavyweight slurries.
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.
Fluid Loss Control Additives - BASF
Cement slurries can lose water to permeable zones causing a number of problems, such as insufficient mud displacement, high viscosity, unwanted change of set-time, and lack of final compressive strength. Fluid loss additives reduce water loss through the cement filter cake, which makes them especially useful in squeeze cementing.
Why Cement Fluid Loss Additives Are Necessary - …
To convert the total amount of fluid loss into an API fluid loss value, three parameters are needed: the permeable formation area, the mudcake thickness and its permeability. Static: A maximum acceptable value of the thickness of the cake built-up during the waiting on cement …
Fluid Loss Additives - Aubin Group
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.

Fluid loss additives - ScienceDirect
Comparative tables of fluid loss additives can be found in the internet . Fluid loss additives are also called filtrate-reducing agents. Fluid losses may occur when the fluid comes in contact with a porous formation. This is relevant for drilling and completion fluids, fracturing fluids, and cement slurries.
OMNOVA Solutions - Cement Additives
Cement Additives. Our advanced liquid and dry cementing latices enhance several key cementing properties, allowing for simpler slurry designs. These additives can be used across a wide range of design densities to extend the slurry, enhance stability, control fluid loss, and mitigate gas migration.
Fluid Loss - an overview | ScienceDirect Topics
A fluid loss additive is described [57] that helps to achieve a desired fracture geometry by lowering the spurt loss and leak-off rate of the fracturing fluid into the surrounding formation by rapidly forming a filter cake with low permeability. The fluid loss additive is readily degraded after the completion of the fracturing process.

US5009269A - Well cement fluid loss additive and …
A fluid loss additive for addition to a cement slurry used in cementing a casing string in a wellbore. The additive reduces loss of water from the slurry into the formation, resulting in a better cement job. The additive is comprised of partially hydrolyzed polyvinyl acetate polymer, calcium sulfate, a crosslinker for the polymer, and optionally a defoamer.

Cement Slurry Laboratory Testing - Better Well …
Cement slurries employed in narrow annular gaps, < 3/4” clearance, might require lower fluid loss values. For squeeze cementing we define the fluid loss according to the stone objectives, the formation permeability, and the fluid injection rate. The following table provides a reference to select the required fluid loss …
Cement Additives (function and definition) | …
Excessive fluid loss will reduce slurry volume and give less cement fill. When squeeze cementing it is desired to get an effective squeeze against the entire formation and not just squeeze cement filtrate into it. Most fluid loss additives tend to viscosify the slurry and consequently, dispersants are often added at the same time to control ...
