Abstract

Authors: Bob Dennis, Gary Wood Schlumberger of Canada Corrosion control in the industry is essentially a cost containment excercise; the likely cost of a failure being balanced against the expenditure on a corrosion control program. All to often corrosion is not considered during the planning stages of a field and most corrosion programs result from an adverse inspection report or an actual failure. Cathodic protection systems are becoming the only realistic solution to most fields corrosion problems.
