Modelling the role of acidic species on CO2 corrosion prediction

The presence of acetic acid (HAc) in formation water of oil and gas reservoirs has long been suspected to contribute to the CO2 corrosion rate. The prediction model has been developed based on mechanistic theories which is involved the fundamental of electrochemical reaction for partial cathodic and...
