Product Sheet SP101 Water-Based-Mud Fluid Loss Control Additive
Used to reduce fluid loss in freshwater and seawater muds.
SP-101* sodium polyacrylate copolymer 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 copolymer is an effective additive for reducing fluid loss and stabilizing rheology in a wide range of water-base systems, including low- solids, non-dispersed 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, non-dispersed polymer systems such as the Poly-Plus* system and in high-temperature applications. Normal treatments range from 0.5 to 1 lb/bbl (1.43 to 2.85 kg/m3).
A viscosity “hump” can occur in non-dispersed or high-solids systems with the initial addition of SP-101 additive (when the concentration is low, ~0.1 lb/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 lb/ 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 Material Safety Data Sheet (MSDS).
SP-101 additive is packaged in 50-lb (22.7-kg), multi-wall, 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/or stacking.
