IRON CONTROL

IC-AS-140N Ferric hydroxide causes formation damages 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. IC-AS-140N ions in the live and spent acid to help preventing 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).
IC-AS-140N Prevents the precipitation of iron compounds from acid solutions, restoring permeability and therefore fluid production following acid stimulation treatments.

Features

IC-AS-140N additives in oil and gas wells stimulation can be used as one of the following three ways:

• As a chelating agent.
• As a reducing agent and.
• As a pH control agent.

IC-AS-140 is a chelating agent and iron control agent which is effective in a wide range of acid solutions and down whole temperatures.

Properties and use

Benefits

This additive is used primarily in acid stimulation treatment fluids to prevent precipitation of ferric hydroxide [Fe (Ill)] as the pH of the fluid rises. These types of iron control also are used to control and reduce the amount of induced asphaltene sludge during acidizing oil wells.

• It is an effective iron-control material.
• It is suited for acidizing associated with disposal and Injection wells where an iron deposit is present.
• The system can be used in the stimulation of oil and gas producing Wells.
• Soluble in both acid and water.
• Compatible with all acid additives.
• Easy to mix and handle.
• Control iron hydroxide to pH 3.

Packing

AS-140N is packed in 220 liters. Standard polyethylene drum.

Storage conditions

AS-140N should be stored in tightly closed containers indoors and maintained in normal temperature. In these conditions, the product is stable for 2 years from its production date.
