Dispersants

Dispersants improve mixability properties of the cement slurry. They also act as rheology modifiers, reducing the viscosity at surface conditions without affecting downhole performance.

>> Low temperature dispersants

– for BHCT below 200F

Function: Dispersant

Application: Temperature up to 105 degC

Description: Red coloured, water soluble powder. (not restricted, non hazardous)

Primary purpose: Dispersant to reduce the viscosity of cement slurry and assist in the provision of low fluid loss values (in combination with FLAC additives). It can be used in concentrations from 0.3% to 2.0% of the cement make-up water.

Guidelines for use: This product is an anionic Polymer Keton resin and is used as a friction reducer or turbulent flow inducer (TIC), compatible with fresh and/or salt water systems.

It performs synergistically with PVA-type Fluidloss additives.

It is compatible with all classes of API cement.

>> High temperature dispersants

– for BHCT above 200F

Function: Dispersant

Application: High temperature

Description: Tan powder

Primary purpose: Low molecular weight polymeric dispersant which is effective at elevated temperatures in cement slurry mixtures to disperse and retard cement compositions.

Guidelines for use: Product acts as retarders and cement rheology stabilizer and is particularly effective at elevated temperatures. This additives can also prevent fluid loss and provide gas migration control when formulated.

Function: Dispersant

Application: High temperature

Description: Sulfonated polysterene

Primary purpose: Sulfonated polysterene, used as anti-static agent

Guidelines for use: Product acts as retarders and cement rheology stabilizer and is particularly effective at elevated temperatures. This additives can also prevent fluid loss and provide gas migration control when formulated.
