8 Corrosion Mitigation by the Use of Inhibitor Chemicals Available to Purchase

The most commonly used approach to manage the threat of internal metal loss corrosion of carbon and low alloy steels (CLASs) exposed to produced fluids containing acid gases is treatment with a corrosion inhibitor. For such applications, corrosion inhibitors have been the primary corrosion control option for over 60 years. In the early 1950s the discovery that high molecular weight, long-chain organic molecules behaved as corrosion inhibitors revolutionised the upstream oil and gas industry, providing the ready and flexible ability to effectively treat sweet and sour systems and therein greatly extend the use of CLASs.
