Wellbore corrosion and failure assessment for CO2 EOR and storage: Two case studies in the Weyburn field

Both wellbores exhibited signs of corrosion, with corrosion ranging from small pits to complete penetration through the casing. Contributing factors to corrosion in these wells range from exposure to injected fluids, injected CO2, packer placements, formation fluid exposure, and the corrosive environment that is present in the perforated area of the well.
