WATER-DISPERSIBLE POLYMER POWDER COMPOSITIONS FOR CEMENTING IN SUBTERRANEAN FORMATION, THEIR MANUFACTURE AND USE
Water-dispersible polymer powder composition for use as additive in cementing in subterranean formations comprising at least particles of a styrene-butadiene polymer, a water-soluble polymer, and a non-ionic emulsifier, wherein the styrene-butadiene polymer particles are at least partly covered by and/or embedded in a composition comprising at least the water-soluble polymer, process of making such compositions, by spray-drying an aqueous dispersion comprising said particles of a styrene-butadiene polymer and a water-soluble polymer, wherein at least one non-ionic emulsifier is added before or after spray-drying, and the use of such water-dispersible polymer powder compositions for cementing in subterranean formations penetrated by at least a well bore.
