Iron control additives

Product Information

IC-2

IC-2 is an iron control additive that reduces ferric iron in live acid and sequesters dissolved iron in spent acid. IC-2 is recommended for use in 15% hydrochloric acid blends up to a maximum temperature of 80°C (176°F).

Advantages

• Dispersible and non-reactive with additives at temperatures up to 80°C (176°F)
• Will not precipitate out in the absence of dissolved iron.
• Capable of sequestering in excess of 5000 ppm ferric iron dependent on additive concentration.

IC-3

IC-3 is an iron control additive that chelates dissolved ferric iron in spent acid. As a chelating agent, IC-3 can be used as an iron control in gas wells and condensate wells that do not pose an asphaltene precipitation issue. Ferric iron re-precipitates from acid once the pH rises above 1.8. IC-3 will prevent the precipitation of ferric iron that is solubilized into the acid during the treatment, therefore preventing damage to the formation. IC-3 is active at any temperature up to 200°C (392°F).

Advantages

• Dispersible and non-reactive with additives at all temperatures
• Does not decompose at elevated temperatures
• Will not precipitate out in the absence of dissolved iron
• Capable of chelating in excess of 5,000 ppm ferric iron dependent on additive concentration
• Can be used in HCl solutions up to 28% concentration

IC-8

IC-8 is an iron control additive that quickly reduces ferric iron in both live and spent acid. Ferric iron is often dissolved into solution during acidizing when the acid contacts treating iron, tubing/casing, and iron based minerals/scales. Ferric iron can cause damage in acidizing by two mechanism; sludging of oil and precipitation of ferric hydroxide. IC-8 is active at temperatures to 110°C (230°F).

Advantages

• Dispersible and non-reactive with acid additives
• Capable of reducing up to 30,000 ppm ferric iron dependent on additive concentration
• Catalysts are not needed at lower acid strength
• Non corrosive
• Can be used in HCl solutions up to 28% concentration
