IRON CONTROL ADDITIVES

Controlling the precipitation of dissolved iron during acidizing treatments is important to prevent permeability reductions, formation of asphaltene sludges, and the development of iron stabilized emulsions. Shrieve's Iron sequestering agents maintain iron in solution and prevent it from precipitating as the acid spends.
