Fluid Loss Control Additives

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.

The Polytrol^® FL line of products are effective fluid loss control chemicals for use in differing conditions and requirements, such as high temperatures and high salt concentrations.

Polytrol® FL 29

Polytrol^® FL 29 is a dispersing fluid loss additive

For primary or squeeze operations through a wide temperature range up to 280 ºF
Acts as a mild retarder
It’s dispersing effect permits the design of low viscosity slurries. A separate dispersant may not be needed
Compatible with all classes of cement and a wide variety of typical cement additives
Appropriate for fresh or seawater, but not for slurries loaded with salt
Helps to keep the horsepower low by controlling viscosity and circulation pressures
Non-hazardous

Polytrol® FL 32

Polytrol^® FL 32 is a dispersing fluid loss additive

Excellent filtration control and flow properties in oilwell cement slurries up to 200 ºF
Permits the design of low-viscosity slurries
A very mild retarder, even at temperatures as low as 100 ºF
Specifically suited for shallow well cementing
Outstanding performance in salt concentrations up to 18%
Non-hazardous

Polytrol® FL 34

Polytrol^® FL 34 is a high-performance, non-retarding fluid loss additive

Excellent fluid loss control in oilwell cement slurries up to 400 °F
The non-retarding properties are also ideal in light cement compositions that often have extended thickening times
Excellent performance in salt concentrations up to 18%
Provides right angle set of cement slurries preventing gas migration into the cement column
Non-hazardous

Polytrol® FL 45

Polytrol^® FL 45 is a high-performance fluid loss additive

Excellent fluid loss control in oilwell cement slurries up to 400 °F
Very mild retarder, even at temperatures as low as 100 ºF
Specifically suited for shallow well cementing
Excellent performance in salt concentrations up to 18%
Provides right angle set of cement slurries preventing gas migration into the cement column
Specially compatible with dispersants and retarders
Non-hazardous

Polytrol® FL 56

Polytrol^® FL 56 is a high-performance dispersing fluid loss additive

Excellent fluid-loss control in high temperature wells
Especially effective when used in slurries with high salt concentration or slurries which may include a weighting agent
Performs well over a wide temperature range of up to 400°F or even above
Excellent performance in salt concentrations up to 18%
Does not tend to increase viscosity which also makes it ideal for slurries mixed with strength-stabilizing agents such as silica flour
In many cases there is no need for an additional dispersant
Non-hazardous
