Experience in the Use of 13% Cr Tubing in Corrosive CO2 Fields

Summary This paper discusses the following points in detail: the reasons for using 13% Cr steel tubing in corrosive offshore wells; the corrosion resistance to be expected with this material; the precautions to be taken both at the completion design stage and during practical implementation; the economic evaluation that can be made after 8 years of experience and that covers 140 wells; and the rationalized use of 13% Cr steel tubing based on early prediction of the corrosivity of future wells.
