Paper: Iron Minimizing Problems And Maximizing Treatment Effectiveness

The precipitation of iron compounds following well treatment is a common problem in most areas of Texas and New Mexico. This insoluble gelatinous precipitate is both an effective plugging agent and an emulsion stabilizing agent. Either condition damages permeability and greatly restricts production of oil and gas. In order to effectively deal with the problem, the chemistry and physical characteristics of iron as an ion and its subsequent reactions must be understood. Sources of iron, well conditions, types of iron control agents and their properties will be discussed and evaluated.
