SPERSENE CF

Chrome-free lignosulfonate deflocculant for all water-based muds

SPERSENE CF chrome‐free lignosulfonate compound is specially formulated to act as a deflocculant in virtually all water‐base mud systems. SPERSENE CF additive reduces and stabilizes viscosity and assists in reducing fluid loss.

Applications

SPERSENE CF additive is intended for use as a deflocculant and fluid loss additive in all types of water‐base systems. These include freshwater, seawater, saturated saltwater, lime and gyp base‐fluids. Laboratory tests and field usage show the deflocculating ability of the material in the presence of contaminants and increasing temperature.

SPERSENE CF additive is added easily to the mud system through the mud hopper. The required concentration of SPERSENE CF additive is a function of desired viscosity or fluid loss. Although SPERSENE CF additive does aid in reducing fluid loss, supplementary additives may be required to achieve a desired level of fluid‐loss control. Also, SPERSENE CF additive shows maximum effectiveness when the pH is controlled in the 9.0‐11.0 range.
