Well cementing
A hydraulic well cementing composition is disclosed. The well cementing composition contains a hydraulic cement and a fluid loss additive. The fluid loss additive is the polymerization reaction product of a two vinylamide monomers, wherein the polymerization reaction is conducted in the presence of a molecular weight control agent. One of the vinylamide monomers includes a sulfonic acid function, the second vinylamide monomer does not include a sulfonic acid function. The fluid loss additive controls fluid loss at temperatures up to 350° F.
