As global demand for oil and natural gas continue to grow the search for additional reservoirs has lead to operations more extreme environments. These environments can contain high concentrations of H2S dissolved in production fluids. The purpose of this study is to examine the effects of H2S concentration on the corrosion degradation of high strength low alloy steels over a range of temperature and basic pH conditions. In situ electrochemical measurements were performed in a well-stirred autoclave at temperatures from 20 to 200 °C. H2S concentrations were varied from about 1 % to just below 100 % saturation in water at 25 °C for pH ranging from 7 to 12. Linear polarization resistance electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation were employed to measure the corrosion properties and rates over time. The EIS results were used to examine the changes in charge transfer and mass transport behavior of the corrosion process over the varying conditions. Post-corrosion surface analyses and thermodynamic calculations were also performed to determine the nature of the corrosion films.
