Gas migration control additive for intermediate temperatures

D600G GASBLOK gas migration control additive is an aqueous dispersion of latex particles with surfactants. It creates an impermeable barrier, preventing annular gas migration into the cement slurry during the critical hydration period. When formation gas enters the slurry, the latex particles coalesce to form a coherent, low-permeability plastic film that blocks further migration into the cement. The additive also controls gas migration by improving the cement bond to the casing and formation interfaces.

Creation of a thin, low-permeability filtercake that reduces fluid loss from the cement slurry is an added advantage. D600G GASBLOK additive is suitable for temperatures ranging from 150 to 300 degF [66 to 149 degC].
