Abstract:
1. A method of cementing in a subterranean formation, comprising: combining at least saltwater, a cement, a latex, a first latex stabilizer comprising a surfactant having the formula: wherein R is an alkyl group having in the range of from about 10 carbons to about 20 carbons, m is an integer in the range of from about 10 to about 40, X is OSO 3 or SO 3 , and M is a compatible cation, and a second latex stabilizer comprising an alcohol ether sulfate having the formula: wherein R 1 is an alkyl group having in the range of from about 4 carbons to about 12 carbons, n is an integer in the range of from about 1 to about 10, and M is a compatible cation to form a saltwater cement composition, wherein the first latex stabilizer and the second latex stabilizer are combined with the saltwater prior to combining the latex with the saltwater; introducing the saltwater cement composition into the subterranean formation; and allowing the saltwater cement composition to set in the subterranean formation.
