Operational experience of using 13% Cr tubing are presented in this article with notable examples of its use as production tubing. The philosophy in deciding to move towards the use of 13% Cr steel tubulars is described based on either laboratory studies indicative of the need for a corrosion resistant alloy or high corrosivity of producing wells on carbon steel tubing. The experience is wide ranging from gas and oil production to sweet and sour conditions. The choice has proved extremely successful in controlling high corrosion in both gas and oil producing fields and in artificial lift oil wells.
