Riteks VAE-RS powders are water redispersible vinyl acetate-ethylene copolymer powders that are readily dispersible in water and form stable emulsions to impart excellent fluid loss for fluids. These powders give enhanced gas migration control to cement slurries, with a minute effect on extending slurry set times. They help in reducing permeability with improved particle-to-particle bonding, improved cement durability during perforation and increased cement longevity. VAE-RS powders also provide improved adhesion, flexural and tensile strength, abrasion resistance, water retention, plasticity and workability.
RFL-70X is a cementing additive that controls flow and fluid loss properties at bottom-hole circulating temperatures up to 210°F (99°C). Typical loading levels of up to 1 percent is normally sufficient at temperatures between 75°F and 200°F (24°C to 93°C) to help reduce fluid loss to 50cc. At temperatures up to 350°F (177°C), this additive can also provide free water control, chemical resistance, shear bonding properties, and thermal shock reduction.
Riteks RFL-4 is a fluid loss additive is that is easily dispersed and dissolved to produce solutions of varying viscosities. RFL-4 is used as a viscosifying fluid loss additive that provides consistent results, viscosity, water retention, and has great suspension qualities. Riteks RFL-4 is a free-flowing, granular powder that dissolves readily in water to give clear, smooth solutions, which exhibit a pseudoplastic flow behavior. Riteks RFL-4 is ideal for circulating long columns of cement slurry on primary casing jobs and for deep liner cementing. It helps maintain fluidity, eliminate premature dehydration, and prevent annular bridging in a tight annulus when cementing is performed form 80°F to 360°F. Riteks RFL-4 is compatible with most additives used in cementing, and also helps provide good frictional properties during displacement
