GMA #1 (Gas Migration Additive)   Description: GMA #1 is a stable liquid polymer complex used to prevent gas or fluid migration from high pressure reservoirs into a cement column.   Application: This material also enhances fluid loss control and slurry dispersibility.This Gas Control Additive is in liquid form, and it effectively controls annular gas migration for the temperature range of 80°F to 450°F. It prevents gas buildup on the surface, prevents interzonal communication, and minimizes the need for costly repetitious remedial cementing.   Mixing: Prior to slurry preparation, mixing equipment must be thoroughly clean, and the drilling mud must be conditioned and removed mechanically and chemically (GLO chemical washes and spacers).   Requirements: The volume of GMA # 1 slurry required depends on the fracture gradient, gas pressure, and properties of the gas zone. A slurry volume that provides 300 to 600 ft of annular fill above the gas zone and 150 to 300 ft of annular fill below the gas zone is generally sufficient.   Packaging: 5-Gallon Pails 3.5 Gallons Net
