Iron Control

Iron sulfide exists in all oilfield applications where oxygen and water reside. Left untreated, the iron can preciptate and interfere with the fluid system in stimulation applications. In production and pipeline applications, iron sulfide can significantly reduce production or flow, respectively. Innospec Oilfield Services offers iron control, either as a preventative or customized solution, depending upon survey results.


FeroCheck™ is a mild organic acid primarily used in acid stimulation to control iron generated from break down acids. FeroCheck is a reducing agent added to the treatment to reduce any iron (III) to iron (II) ions (ferric to ferrous) before they enter the formation. It also helps lower the pH level of the fluid, offsetting the effect of iron precipitation that can cause damage to the permeability of the formation.
