摘要
This invention discloses a composition and a method of using the composition to cement a borehole penetrating a subsurface earth formation. The composition, the random polymerization product of two or three different vinyl-containing monomers including a vinylamide morpholine derivative, operates to reduce fluid loss from the cement slurry used to cement the borehole to the subsurface formation.
