... to improve the oil recovery (Wright et al., 2018 ; Tian et al., 2017 ; Mansoori et al., 2018 ; Liu et al., 2016). Therefore, CO₂ corrosion of pipeline steel is an inevitable problem in the petrochemical industry. Although alloy steel could be used instead...

... pipeline steel. The weight loss tests were carried out in a 3 L autoclave, and effects of water cut and temperature on the CO₂ corrosion rate of X65 steel were studied. Electrochemical studies were carried out in a three-electrode electrochemical cell with the test temperature was 60°C...

...Jhonatan Jair Arismendi Florez; Jean Vicente Ferrari Purpose Among the many influencing effects that the medium has on the CO₂ corrosion of carbon steel, flow is one of the most important because it can determine the formation of corrosion product scales and its stabilisation, thus...

... out in a 3L autoclave, and effects of flow velocity, CO₂ partial pressure and water cut on the CO₂ corrosion rate of X65 steel were studied. Electrochemical studies were carried out in a three-electrode electrochemical cell with the test temperature of 60°C and CO₂...

... it can be calculated by Dalton’s law for partial pressures, which is shown as equation (7): CO₂ partial pressure is one of the main factors of the CO₂ corrosion, so calculating CO₂ partial pressure correctly is important for downhole tubing anticorrosion design...

.... Approximately 60 per cent of the failures in oilfields are related to CO₂ corrosion. This failure mechanism is related mainly to the low corrosion resistance of carbon steel and to lack of predictive models (Kermani, 1997). CO₂ corrosion has been reported as the most prevalent form...
