IRON CONTROL

IC-AS-140N Ferric hydroxide causes formation damage and consequently reduces the permeability and is a potential problem during any acidizing treatment.
This iron control agent is used in a wide variety of applications where iron control is required. IC-AS-140N is the most economical and efficient chelating agent for controlling iron and can be used in all acid solutions including 15-28% HCl and HCl-HF systems. It controls Iron ions in the live and spent acid to help prevent the precipitation of iron in the acid solution. Surfactants and mutual solvents can be added to the acid solution in the normal way. The concentrations can be doubled when treating formations containing Siderite or a high concentration of soluble iron. The normal concentration is 5 to 30 gal/1,000 gal (0.5 to 3 Volume percent).
Iron control Prevents the precipitation of iron compounds from acid solutions, restoring permeability and therefore fluid production following acid stimulation treatments.
