Over the past decade the knowledge related to predicting internal pipeline corrosion for both sweet and sour environments has dramatically improved. Advancement in understanding the corrosion mechanisms related to CO2 corrosion environments include expanding the range of temperatures from as low as 1°C up to 250°C expanding the range of CO2 partial pressure up to supercritical and defining the chemo-mechanical forces which occur at the pipe wall and may lead to localized corrosion. Advancement in the understanding of corrosion mechanisms related to H2S corrosion environments include the development of an electrochemical model for H2S corrosion the effect of H2S on the corrosion product that will form on mild steel and the implications towards an increased chance of localized corrosion whenever H2S is present. Even though a lot has been learned over the past decade the demand for more research continues. As the knowledge base for predicting the influence of corrosive environments on production pipelines increase so do the advancements in drilling technology which expose these systems to more extreme environmental conditions.

Mild steel specimens (API 5L X65) were pretreated to form a pyrrhotite layer on the surface using high temperature sulfidation in oil, then exposed to a range of aqueous CO2 and H2S corrosion environments, leading to initiation of localized corrosion.
