Achieving successful acidizing in the oil and gas industry requires effective iron control. Ferrous and ferric iron contamination can lead to costly problems. These include reduced reservoir permeability and essential equipment.
Sunita Hydrocolloids Inc., USA (SHI) provides advanced iron control solutions. Our iron control in acid treatment helps maintain well integrity. It also 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. This 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. As pH rises after acidizing, insoluble iron compounds precipitate. Iron hydroxide and iron sulfides plug pore throats. The presence of ferric iron during acid treatments can lead to the precipitation of colloidal ferric hydroxide. This drastically reduces permeability.
The result is a significant decrease in production rates. Effective iron control strategies are therefore essential. The use of iron control additives is necessary in most acid treatments to remove free iron. They are also the sludge control agents that result in the prevention of sludges in contact with certain crude oils.
Sunita Hydrocolloids Inc., USA (SHI) utilizes advanced chelates 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.
Sunita Hydrocolloids Inc., USA (SHI) focuses on creating iron control in acid treatment that works in challenging conditions. Our chemical solutions are designed for thermal stability. They also maintain their effectiveness in strong acids found downhole.
The selection of the appropriate iron control agent is crucial. Consider parameters such as pH and temperature. Iron concentration and the specific acidizing fluid are also important. Partner with Sunita for advanced iron control.
