Riteks RFL-4 is a high viscosity fluid loss polymer that easily disperses and dissolves to produce solutions of varying viscosities. It is a viscosifying fluid loss additive that provides consistent results, viscosity, water retention, and suspension additive. 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 fluidity maintenance, premature dehydration elimination, and annular bridging prevention in tight annuls. Most additives used in cementing are compatible with Riteks RFL-4 and helps provide good frictional properties during displacement.

Features and Benefits

• Controls fluid loss of cement from 80 to 360F BHCT
• Offers better control of slurry downhole by helping eliminate premature dehydration
• Functions effectively in slurries containing up to 18% NaCl or 5% KCl
• Helps protect water sensitive shales and can reduce premature bridging in annuli, which may be caused by dehydration
• Can reduce slurry water losses, thus maintaining more consistent viscosities and circulating pressures
• Helps control gas leakage while cement is setting
• Helps reduce premature dehydration in tubing and casing while perforations are squeezed
