Achieving successful acidizing in the oil and gas industry requires effective iron control as ferrous and ferric iron contamination can lead to costly problems such as reduced reservoir permeability and damage to essential equipment.
Sunita Hydrocolloids Inc., USA (SHI) provides advanced iron control solutions. Our iron control in acid treatment helps maintain well integrity and maximizes the benefits of stimulation. Learn how our superior iron control can improve your operations.
Iron contamination poses a serious threat to acidizing operations. It originates from several sources in the wellbore – corrosion of tubulars releases free iron. Ferric hydroxide forms a precipitate that can block formation permeability, exacerbate sludging and reduce well productivity. Thus, precipitation of iron compounds and dissolution of iron minerals occur within the formation.
Iron scale also contributes to the problem. The presence of the two classes of iron ions – ferrous (Fe2+) and ferric (Fe3+) ions in spent acid causes formation damage. Iron hydroxide and iron sulfides plug pore throats. The presence of ferric iron during acid treatments leads to the precipitation of colloidal ferric hydroxide, which drastically reduces permeability.
The result is a significant decrease in production rates. Effective iron control strategies are therefore essential. They also help prevent sludge that results from the interaction of iron and crude oil.
Sunita Hydrocolloids Inc., USA (SHI) utilizes advanced chelant chemistry for superior iron control. We are a leading supplier of high performance iron control chemicals. Our product line features different types of iron control agents. Chelating agents like EDTA, DTPA and citric acid effectively bind iron. Reducing agents such as erythorbic acid help in the prevention of precipitation. Copper combined with iodine also catalyzes the reduction of ferric iron in acid treatments.
