A study of corrosion in the mixing zone at the front of slugs has been carried out in a 10 cm internal diameter, horizontal, three-phase flow system using a light condensate oil and saltwater as liquids and carbon dioxide as the gas phase. Visual observations show that stratified water layers are apparent at the bottom of the pipe at oil compositions up to 60%. Pulses of gas bubbles are formed at high Froude numbers which impinge on the lower surfaces of the pipe. The corrosion rate increased with an increase in Froude number. This is due to the increases in wall shear stress, turbulence, and gas present at the bottom of the pipe as the Froude number increases. The presence of gas at the bottom of the pipe has a significant effect on the corrosion rate. It provides an erosion component to the corrosion processes. The corrosion rate can be related to pressure drop across the slug but average wall shear stress does not seem to be appropriate.
