The Effects of Carbon Dioxide Saturated Water on the Steel Tubing of a Well Abstract Carbon dioxide flooding is a commonly used method of recovering petroleum resources from a reservoir. Injection wells are used to pump carbon dioxide saturated water into a reservoir and are produced, along with the hydrocarbons, up the production well. Carbon dioxide is very corrosive when in contact with the steel tubing. The focus of this project was to study how quickly the carbon dioxide corrodes N-80 and J-55 steel tubing. In addition, a common corrosion inhibitor was used on the steel to investigate the effectiveness of the inhibitors on steel tubing. To accomplish this, a sample of the tubing was placed in a solution of carbon dioxide saturated water and a computer measured the rate of oxidation in the solution. Tafel plots were used to interpret and examine the data from the experiment. Biography
