Roark, D N; Nugent, A Jr; Bandlish, B K

In a process of cementing subterranean well formations employing an aqueous well cement slurry, this patent describes the improvement characterized in that the slurry contains a gelatinous material that tends to plug porous zones and minimize premature water loss from the well cement slurry when present in the subterranean well formation. The gelatinous material is formed by interaction in the presence of water between (i) a sulfonated polymer and (ii) a polymer of monoallylamine.
