Investigation Of The Influence Of Scaling On Corrosion Behavior Of Tubing In Oil Wells

Calciumiron carbonate and bariumstrontium sulfate are major scales in downhole condition of oil wells. Formation of scale in wellbore and inside tubulars not only reduces the production rate but also influences the corrosion of metallic materials. It is widely accepted that formation of some scales such as iron carbonate and iron sulfide help protection of metals form corrosion attacks. While some other scales do not offer protective properties due to their different physicochemical properties such as porosity and density. This paper discusses the common type of scales in oil wells and their possible influence on corrosion behavior of metallic infrastructure. The paper particularly focuses on ironcalcium carbonate and bariumstrontium sulfate.
