Fluid Loss Additive

BT-F500S is a water-soluble synthetic polymer with strong dispersive properties in powder form，which can control fluid loss through Adsorption and aggregation reducing pore size and enhancing viscosity of water phase.

BT-F500S fluid loss additive is nonretarding, which makes it ideal for lightweight cementing compositions that typically have long thickening times. The additive promotes good compressive strength at low temperatures, and it performs well in seawater and fresh water.

It can be used with seawater, and high concentrations of salt. Specially designed for the application in low density cement slurry system.Generates thickening effect on the cement slurry and enhances cement slurry’s suspension stability. cement slurry system is stable with little free fluid. It provides exceptional filtrate control when used with retarders at bottom hole circulating temperatures up to 410°F (210°C). BT-F500S may be used for fluid loss control in any API class cements (A, C, G, H or cement blends). It may be used with other cement additives such as Oil Energy’s dispersants, retarders and defoamers.
