GENERAL DESCRIPTION: Fluid loss additive TRCF-252S is produced by copolymerization of ethylene monomers. Slurries with TRCF-252S have good rheology, anti-salt ability and slight dispersing effect. TRCF-252S is effective in a wide range of temperature. It is applicable for wide range of salt formations (salt concentrations of up to 36%) and high temperature wells. It is compatible with retarders, dispersants, and CaCl2.
