Cement/ Fluid Loss Contol

Fluid loss control additives are designed to reduce water loss from the slurry to the formation. This protects sensitive formations from damage and avoids premature dehydration of the slurry, giving better results in squeeze jobs. In a narrow annulus, if the loss of fluid to the formation is excessive, a layer of filtrate will build up on the walls causing reduced flow and increased friction pressures due both to the restricted flowpath and the higher viscosity of the slurry; in some cases this filtrate can bridge the annulus.
Some fluid loss control additives also act as gas migration control additives. These prevent gas from channelling through the slurry as it sets and the hydrostatic load is reduced.

CFL-109 is a powdered fluid loss additive for cement slurries and can be used in a wide range of cementing compositions by varying the concentration to give the required fluid loss value.	CFL-109
CFL-114 is a retarding, low fluid loss cement additive for use above 180F circulating temperature.	CFL-114
CFL-122 is a cement fluid loss additive developed for use over a wide range of temperatures and slurry types.	CFL-122
CFL-259 is a powdered fluid loss additive suitable for cement slurries containing salt (sodium chloride). The preferred temperature range for CFL-259 is below 140F BHCT, but it can be used successfully at much higher circulating temperatures.	CFL-259
CFL-260 is a fluid-loss control agent designed for use in cement slurries prepared with fresh water. CFL-260 can be used with any brand of cement. It can be used in the temperature range of 40 to 200°F (4 to 93°C), but exhibits a retarding effect at the low end of this range.	CFL-260
CFL-308 is a premium grade of CMHEC suitable for cementing work. It offers low water loss properties as well as retardation in both fresh and salt water slurries.CFL-308 is commonly used in low to medium temperature wells.	CFL-308
CFL-386 is a fluid loss and gas migration control product equivalent to Dowell Schlumberger's D600.	CFL-386
CFL-395 is a powdered fluid loss additive with only slight retarding properties for the slurry. It is primarily for use at low temperatures, i.e. BHCT of 180F/82C or less, but can be used at higher BHCTs.	CFL-395
CFL-450 is a mid to high range temperature fluid loss control additive for use in oilwell cement slurries.	CFL-450
CFL-56G is a fluid loss and gas control additive that controls fluid loss, bonding and filtrate viscosity by imparting cohesive and adhesive properties to cement slurries. CFL-56G can be used up to 200F.	CFL-056G
CFL-609 is a very effective fluid loss control agent that is effective at a wide range of temperatures from 60F to 300F in most types of cement slurry.	CFL-609
CFL-622 is a very effective fluid loss control agent that is effective at a wide range of temperatures from 60F to 300F in most types of cement slurry.	CFL-622
CFL-644 is a non-retarding fluid loss control agent that is effective at temperatures up to 400F in most types of cement slurry.	CFL-644
