Fluid Loss Additives

BT-14S 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.

It can be used with seawater, and high concentrations of salt. There can be some slight retardation and dispersive at temperatures below 147.6°F (50°C) and strong dispersive. It can reduce the amount of retarder and dispersant in cement slurry. It is recommended to use (BT-14S dosage 0.65%BWOC) with BT-S1 (Suspending Aid dosage 0.3%BWOC). It is ideally suited for squeeze cementing particularly in coil tubing due to its non-gelation properties. In primary cementing, it functions as a gas migration control additive because of its non-gelation characteristics. It provides exceptional filtrate control when used with retarders at bottom hole circulating temperatures up to 410°F (210°C). BT-14S 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.
