Gas migration control additive for intermediate temperatures

D600G GASBLOK gas migration control additive creates an impermeable barrier that prevents annular gas migration into cement slurry during the critical hydration period.

The additive is an aqueous dispersion of latex particles with surfactants that improve dispersion and add stability. When formation gas enters the cement slurry, the latex particles coalesce to form a coherent, low-permeability plastic film that blocks further migration into the cement.
