Sp-101

SP-101
SP-101 sodium polyacrylate copolymer is a medium-molecularweight,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 degradationTypical Physical PropertiesPhysical appearance- off- white to cream flakes (powder)Specific gravity- 1.05pH (1% solution)- 7Bulk density- 24.5 Ib/ft3 (392 kg/m3)ApplicationsSP-101 is an effective additive for reducing fluid loss and stabilizing rheology in a wide range of waterbase 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 is used most often in low-solids, non-dispersed polymer systems such as the POLY-PLUST 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" may occur in non-dispersed or high-solids systems with the initial addition of SP-101 (when the concentration is low, ~0.1 lb/bbl [0.29 kg/m3]). Subsequent treatments will reduce this viscosity "hump" in clean, lowsolids muds. SP-101 attaches to clay particles and helps to form a protective colloid on exposed shales and encapsulated cuttings. SP-101 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.AdvantagesReduces fluid loss and improves filter cake qualityThermally stable to >400OF (>204OC)Not subject to bacterial degradationStabilizes flow properties in hightemperature environments in excess of 400OF (204OC)LimitationsHighly anionic, precipitated by high concentrations of divalent cations such as calcium and magnesiumTotal hardness must be maintained below 320 mg/l with soda ashShould not be used in calcium systems such as lime, gyp or untreated seawater muds that have high concentrations of soluble calciumToxicity and HandlingBioassay information is available upon requestHandle as an industrial chemical, wearing protective equipment and observing the precautions as described on the Transportation and Material Safety Data Sheet (MSDS)Packaging and StorageSP-101 is packaged in 50-lb (22.7-kg), multi-wall, paper sacks.
