Cement Additives (function and definition) | .
Fluid Loss Control Additives. Fluid loss control additives are added to cement slurries for the following reasons: To reduce the possibility of dehydration opposite porous zones and consequently flash setting of the cement. Loss of fluid from the slurry will result in increasing slurry viscosity and gradient and higher circulating pressures. Excessive fluid loss will reduce slurry volume and ...Get Price
Fluid Loss Additives / Cementing Additives by Al .
Our Cement Fluid Loss Control Additives are Designed to Control The Filtration Rate of Many Water-Based Fluid Systems. 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 ...Get Price
cement additive - Schlumberger Oilfield Glossary
Cement additives may be broadly categorized as accelerators, retarders, fluid-loss additives, dispersants, extenders, weighting agents, lost circulation additives and special additives designed for specific operating conditions. Cement additives are commonly available in powder or liquid form, enabling some flexibility in how the cement slurry is prepared.Get Price
Polyamine fluid loss additive for oil well cements .
An aqueous cement composition is shown for cementing the annular space between a pipe and the surrounding bore in a well. The cement composition includes a hydraulic cement, water present in an amount effective to produce a pumpable slurry, a polyamine fluid loss additive, and a sulfonated polymer. By neutralizing the polyamine to a pH of approximately 7, improved free water and fluid loss ...Get Price
fluid-loss additive - Schlumberger Oilfield Glossary

Mechanistic study on carboxymethyl hydroxyethyl .
The working mechanism of carboxymethyl hydroxyethyl cellulose (CMHEC, M w 2.6 × 10 5 g/mol) as fluid loss control additive (FLA) for oil well cement was investigated. First, characteristic properties of CMHEC such as anionic charge amount, intrinsic viscosity in cement pore solution, and static filtration properties of cement slurries containing CMHEC were determined at 27°C and 70 bar.Get Price

Fluid Loss Control - an overview | ScienceDirect .
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. If sufficient water is lost, the cement either produces non ...Get Price
US4602685A - Non-retarding fluid loss additives .
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.Get Price

A talk about API Fluid Loss - Better Well Cementing .
Thinking about the fluid loss test, there is always some cement slurry loss of filtrate (water from the cement) but as the test progresses the rate of filtration reduces with time. This reduction is caused by the building of a filter cake, whose thickness depends on its own permeability. So, to answer the question, fluid loss allows to keep the water in the cement because it builds a barrier ...Get Price
