Precipitation of iron compounds can cause damage to the reservoir permeability or exacerbate sludging issues causing formation damage. Control of the iron with iron control agents is essential to ensure the prevention of formation damage.

These can both be utilized to prevent the mentioned effects; however BASF specializes in chelates chemistry and is able to offer a variety of chelates as iron control agents or sludge control agents.
