Flocele™ lost-circulation cement additive helps control lost circulation. It consists of 3/8-in or 3/4-in cellophane flakes. It is effective at bottomhole temperatures (BHTs) between 60°F and 260°F (16°C and 127°C). Typical additive concentrations are 1/8 to 1/2 lb/sk of cement. Flocele additive is used in lightweight to normal density slurries.
Flocele additive can provide the following benefits:
Provides excellent bridging properties to help seal off lost circulation zones
Does not appreciably change the thickening time of the cement slurry
Does not affect the compressive strength of the cement
Does not chemically interfere with the cement slurry
