The purpose of all oil and gas production systems is to produce safely and economically, dehydrated crude oil and natural gas condensate, dehydrated natural gas, and clean disposable water. Successful corrosion inhibition systems must be designed and applied to alleviate corrosion effectively and reliably without adversely affecting the production
system. This paper details the process, including test results, to develop, apply and monitor a successful corrosion inhibition system for subsea oil and gas wells. KEY WORDS Corrosion, Corrosion inhibition, CO, Corrosion, Deepwater, Subsea, Offshore, Subsea pipelines, Subsea flowlines.
