COMPOSITIONS AND METHODS FOR REDUCING FLUID LOSS IN WELL CEMENTING SLURRIES
A well cementing composition comprises an aqueous fluid, portland cement, styrene-butadiene latex and styrene sulfonate-maleic acid copolymer. The styrene sulfonate-maleic acid copolymer has a molecular weight between 5,000 g/mol and 25,000 g/mol. The composition may be placed in a subterranean well during a primary cementing or a remedial cementing operation.
