Medium-Temperature Applications

The D600G GASBLOK gas migration control cement additive for medium temperatures creates an impermeable barrier that prevents annular gas migration into the cement slurry during the critical hydration period. When formation gas enters the cement slurry, the latex particles coalesce to form a coherent, low-permeability plastic film that blocks migration.

The additive also controls gas migration by improving cement bond to the casing and formation interfaces, and it creates a thin, low-permeability filtercake to reduce fluid loss from the cement slurry.
