Fe-13Cr stainless steel is a corrosion resistant alloy (CRA) that is widely used in oil and gas production for equipment such as tubes in wells. The high temperature, high C02 and H2S partial pressures of typical production environments and the significant amounts of CI" containing water that is produced along with the hydrocarbons affects the corrosion processes. Fe-13Cr is used for tubes since it exhibits passivity and low corrosion rates in production environments. But, during production operations, it is often necessary to pump strong acids into the underground rock formation through the tubes to stimulate the field and increase productivity. This is done in order to dissolve deposits that clog pores in the rock formation, thus improving permeability and facilitating the flow of hydrocarbons. This is expected to significantly degrade the passivity and lead to increased corrosion.
