  • Non-retarding fluid loss additives for well cementing compositions
    Patent number: 4610306
    Abstract: A well bore cementing composition and method are shown in which a hydraulic cement, water and fluid loss additive are combined to form a cementing slurry. The fluid loss additive is a copolymer of a first monomer of dimethyl-diallyl ammonium chloride and a second anionic monomer. The monomer ratio of the non-ionic, water soluble monomer to the anionic monomer is in the range from about 85:15 to 95:5, and the copolymer has a molecular weight in the range from about 200,000 to 400,000.
    Type: Grant
    Filed: December 19, 1984
    Date of Patent: September 9, 1986
    Assignee: Hughes Tool Company

  • Non-retarding fluid loss additives for well cementing compositions
    Patent number: 4602685
    Abstract: A well bore cementing composition and method are shown in which a hydraulic cement, water and a non-retarding fluid loss additive are combined to form a cementing slurry. The non-retarding fluid loss additive is a copolymer of a first non-ionic water soluble monomer which resists hydrolyzing in a cement slurry and a second anionic monomer. The monomer ratio of the non-ionic, water soluble monomer to the anionic monomer is in the range from about 85:15 to 95:5, and the copolymer has a molecular weight in the range from about 200,000 to 400,000.
