Halad®-322 Fluid-Loss Additive

Controls fluid loss in low-temperature environments

Halliburton’s Halad®-322 fluid-loss additive is designed for wells with bottomhole circulating temperatures of 180°F (82°C) and below. Because the additive is also a dispersant, Halad-322 additive works best with slurries with good solids-suspension properties.

Halad-322 additive was designed for shallow wells where other additives can significantly retard compressive strength development. Halad-322 additive is a mild cement retardant, even at temperatures as low as 100°F (37.8°C).

Halad-322 additive is compatible with a wide range of slurries, including those containing 5% KCl, 3% CaCl and up to 18% NaCl by weight of water. The additive is easy to mix, and it enables operators to design low-viscosity slurries for turbulent-flow cementing.

Halad-322 additive can provide the following benefits:

  • Minimize horsepower requirements by controlling viscosity and circulation pressures.
  • Control gas migration and improve squeeze cementing results.
  • Protect water-sensitive formations.
  • Promote better bonds between casing and cement.
  • Maintain slurry density.
