ABSTRACT:
A method of retarding the set time of a cement composition comprising providing a cement composition that comprises water and a cement, and retarding the set time of the cement composition by including a copolymer retarder in the cement composition, wherein the copolymer retarder comprises olefinically unsaturated non-acrylate sulfonate monomers and olefinically unsaturated carboxylic acid monomers. Methods of cementing in a subterranean formation also are provided.
