Gas migration control additive for high temperatures

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.

Temperature range: 250 to 350 degF [121 to 177 degC]
Slurry density range: 8 to 23 ppg [960 to 2,760 kg/m3]
