''Chemical corrosion'' is caused by soluble organic acids within the produced formation water or carbon dioxide within gas in the reservoir. These agents react with the metal and cause severe pitting ([[:file:production-problems_fig3.png|Figure 3]]). The incidence and severity of this type of corrosion is increased with higher bottomhole temperatures. | ''Chemical corrosion'' is caused by soluble organic acids within the produced formation water or carbon dioxide within gas in the reservoir.
