Product Sheet SP-101 Water-Based-Mud Fluid Loss Control Additive
Reduces fluid loss in freshwater and seawater muds.
Water-based-mud fluid loss control additive
SP-101 water-based-mud fluid loss control additive is a medium-molecular-weight, anionic additive used to reduce fluid loss in freshwater and seawater muds. This synthetic additive has a high temperature limit and is not subject to bacterial degradation.

SP-101 additive is an effective additive for reducing fluid loss and stabilizing rheology in a wide range of water-based systems, including low-solids, nondispersed, and dispersed weighted systems. It is most effective in freshwater fluids that are low in soluble calcium. SP-101 additive is used most often in low-solids, nondispersed polymer systems such as the POLY-PLUS system and in high-temperature applications. Normal treatments range from 0.5 to 1 lbm/bbl [1.43 to 2.85 kg/m3].
A viscosity “hump” can occur in nondispersed or high-solids systems with the initial addition of SP-101 additive (when the concentration is low, ~0.1 lbm/bbl [0.29 kg/m3]). Subsequent treatments reduce this viscosity hump in clean, low-solids muds. SP-101 additive attaches to clay particles and helps to form a protective colloid on exposed shales and encapsulated cuttings.
SP-101 additive is also effective as a deflocculant and high-temperature stabilizer in low-solids systems at concentrations greater than 1 lbm/bbl [2.85 kg/m3]. Pilot tests are recommended prior to treating with SP-101 additive.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.
SP-101 additive is packaged in 50-lbm [22.7-kg] multiwall paper sacks. Store in a dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
