The laboratory will be used primarily to test the sulfide stress cracking resistance of carbon steel alloys for oil wells and offshore drilling applications. Testing will be performed at DNV’s labs in Columbus, Ohio, and Norway and overseen by experts in fatigue of subsea equipment, bolting connections, cathodic protection, and instrumented tests. The paper discusses the main factors affecting CO2 corrosion, provides an assessment of what to look for in major equipment, and details recommended material of construction and corrosion mitigation/control methods. With the huge amount of water injection in the industry, the need is paramount for a more scientific approach to materials selection for tubing, especially CRAs. Software-based predictors similar to those developed for CO2 corrosion would improve the economical choice of CRAs.
