D600G GASBLOK gas migration control additive is an aqueous dispersion of latex particles with surfactants. The additive 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 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.
Additionally, the additive creates a thin, low-permeability filtercake that reduces fluid loss from the cement slurry.
![D600G GASBLOK additive can be used in freshwater or saltwater from 150 to 350 degF [66 to 149 degC].](/-/media/images/ce/gas-migration-control/d600-g-gasblock-max.ashx?h=811&w=1000&la=en&hash=E7A6C56C709A0A2FEA7ABCBF4174C3AD)
