Anti-Gas Migration

AGM- 320 HT (Liquid)

AGM-320 is a synthetic polymer used to help prevent gas migration in deep and high temperature conditions. It delays the static gel strength of the cement and lowers the fluid loss of slurry. Unlike latex materials, AGM-320 doesn't need the stabilizer.

This additive controls fluid loss control and increases the slurry to an extent. Adding dispersant will reduce the viscosity of the slurry. AGM-320 can be used in fresh water and salt water cement slurries with temperatures between 40-180°C.

The recommended dosage is 0.5%-1.5% (Bwoc) depending on well’s temperature and solids to water ratio. In case of reducing the dosage it would be possible to achieve a better compressive strength.

AGM- 325 (Powder)

AGM-325 can form slight bubbles which distribute uniformly in cement slurry to compensate pressure decrease which results from gellification weightlessness and hydrating volume contraction, and enhance cementing strength of cement. Therefore, it can prevent oil, gas and water from migrating efficiently. AGM-325 can be used in fresh water and salt water cement slurries with temperatures between 37-150°C. Better expanding results can be achieved by mixing it without water instead of mixing with water.

The recommended dosage is 0.3%-0.6% (Bwoc) depending on well’s temperature and solids to water ratio. It is compounded by foamer, foam stabilizer and fluid loss control additive.
