Cement slurries with salt-tolerant fluid loss additives and methods relating thereto
A cement slurry suitable for use in the presence of high salt concentrations may include a base fluid and dry components that include: a cementitious material, a pozzolanic material, a salt additive, and a salt-tolerant fluid loss additive. The salt-tolerant fluid loss additive may be at least one of the following zwitterionic polymers: (1) a copolymer of at least one anionic monomer and at least one cationic monomer, (2) a copolymer of at least one anionic monomer, at least one cationic monomer, and at least one zwitterionic monomer, (3) a homopolymer of a zwitterionic monomer, or (4) a copolymer of at least one zwitterionic monomer.
