Gas migration control additive
D700 HT GASBLOK gas migration control additive is an aqueous dispersion of latex particles with surfactants. It creates an impermeable barrier that prevents 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 low-permeability plastic film that blocks further migration into the cement.
